were replaced by new 'Focus Meetings'. Astronomy in Focus XXIXA
presents the most relevant contributions from the Focus Meetings
together with summaries of all the accepted papers and posters. It
covers the meetings on the following areas: dynamical problems in
extrasolar planet science; astronomical heritage; scholarly
publishing in astronomy; statistics and exoplanets; the exploration
of small worlds; ground and space astrophysics and heliophysics;
laboratory astrophysics; brightness variations of the Sun and
Sun-like stars; astronomy for development; and mitigating the
threats of light pollution and radio frequency interference. The
publications Astronomy in Focus XXIXA (together with its companion,
XXIXB), the proceedings of the six main Scientific Symposia and
Reports on Astronomy: Commission Legacy Reports, fully cover the
XXIX IAU General Assembly.
This book gives an in-depth analysis of the physical phenomena of
thrust production by laser radiation, as well as laser propulsion
engines, and laser-propelled vehicles. It brings together into a
unified context accumulated up-to-date information on laser
propulsion research, considering propulsion phenomena, laser
propulsion techniques, design of vehicles with laser propulsion
engines, and high-power laser systems to provide movement for space
vehicles. In particular, the reader will find detailed coverage of:
designs of laser propulsion engines, operating as both
air-breathing and ramjet engines to launch vehicles into LEOs;
Assembly of vehicles whereby laser power from a remote laser is
collected and directed into a propulsion engine; and, the
laser-adaptive systems that control a laser beam to propel vehicles
into orbits by delivering laser power through the Earth's
atmosphere. This book is essential reading for researchers and
professionals involved in laser propulsion.
Voted the Best Space Book of 2018 by the Space Hipsters The
dramatic inside story of the epic search and recovery operation
after the Columbia space shuttle disaster. On February 1, 2003,
Columbia disintegrated on reentry before the nation's eyes, and all
seven astronauts aboard were lost. Author Mike Leinbach, Launch
Director of the space shuttle program at NASA's John F. Kennedy
Space Center was a key leader in the search and recovery effort as
NASA, FEMA, the FBI, the US Forest Service, and dozens more
federal, state, and local agencies combed an area of rural east
Texas the size of Rhode Island for every piece of the shuttle and
her crew they could find. Assisted by hundreds of volunteers, it
would become the largest ground search operation in US history.
This comprehensive account is told in four parts: Parallel
Confusion Courage, Compassion, and Commitment Picking Up the Pieces
A Bittersweet Victory For the first time, here is the definitive
inside story of the Columbia disaster and recovery and the
inspiring message it ultimately holds. In the aftermath of tragedy,
people and communities came together to help bring home the remains
of the crew and nearly 40 percent of shuttle, an effort that was
instrumental in piecing together what happened so the shuttle
program could return to flight and complete the International Space
Station. Bringing Columbia Home shares the deeply personal stories
that emerged as NASA employees looked for lost colleagues and
searchers overcame immense physical, logistical, and emotional
challenges and worked together to accomplish the impossible.
Featuring a foreword and epilogue by astronauts Robert Crippen and
Eileen Collins, and dedicated to the astronauts and recovery search
persons who lost their lives, this is an incredible, compelling
narrative about the best of humanity in the darkest of times and
about how a failure at the pinnacle of human achievement became a
story of cooperation and hope.
Owing to the increased accuracy requirements in fields such as
astrometry and geodesy the general theory of relativity must be
taken into account for any mission requiring highly accurate orbit
information and for practically all observation and measurement
techniques. This book highlights the confluence of Applied
Mathematics, Physics and Space Science as seen from Einstein's
general theory of relativity and aims to bridge the gap between
theoretical and applied domains. The book investigates three
distinct areas of general relativity: Exact solutions of the
Einstein field equations of gravitation. Dynamics of near-Earth
objects and solar system bodies. Relativistic orbitography. This
book is an updated and expanded version of the author's PhD thesis
which was awarded the International Astronomical Union PhD prize in
Division A: Fundamental Astronomy. Included is a new introduction
aimed at graduate students of General Relativity and extended
discussions and results on topics in post-Newtonian dynamics and
general relativistic spacecraft propagation.
This book presents the cold side of the Universe illustrated by the
rest-frame, far-infrared emission with Atacama Large
Millimeter/submillimeter Array (ALMA). The author constructed the
largest-ever ALMA sample and dataset, which enables them to
identify very faint, rest-frame, far-infrared dust continuums as
well as the carbon fine-structure line emission from distant
galaxies that have been missed in previous surveys. The
observational findings described in this book reveal for the first
time where and how much of the star formation, traced by the
rest-frame far-infrared emission, is ongoing, from inter-stellar
and circum-galactic media to cosmic structures. Moreover, since
some of the findings are unexpected and as such challenge the
current galaxy formation models, the book provides exciting
questions that should be addressed in the next decades.

Cosmology is the study of the origin, size, and evolution of the
entire universe. Every culture has developed a cosmology, whether
it be based on religious, philosophical, or scientific principles.
In this book, the evolution of the scientific understanding of the
Universe in Western tradition is traced from the early Greek
philosophers to the most modern 21st century view. After a brief
introduction to the concept of the scientific method, the first
part of the book describes the way in which detailed observations
of the Universe, first with the naked eye and later with
increasingly complex modern instruments, ultimately led to the
development of the "Big Bang" theory. The second part of the book
traces the evolution of the Big Bang including the very recent
observation that the expansion of the Universe is itself
accelerating with time.
This book describes some of the frontier problems of cosmology: our
almost total ignorance of what the Universe is made up of, the
mystery of its origin and its end. The book starts with a
description of the historical events that led to the construction
of the Big Bang model together with the stages that transformed the
Universe from a very hot place to a very cold one, full with the
structures that we observe today. These structures (stars,
galaxies, etc.) constitute only 5% of the contents of the Universe.
Concerning the remaining 95%, dubbed dark matter and dark energy,
we know very little, and we have only indirect evidence of their
existence. The text describes the story and the protagonists who
showed the need for the existence of this 'missing matter', the
observations, and puzzles they had to solve to understand that dark
matter was not ordinary matter. The book describes the hunt for
dark matter, carried out with instruments operating in space, on
the Earth's surface, and in laboratories built in the bowels of the
Earth. It also describes dark energy, which manifests itself in the
accelerated expansion of the Universe, and appeared only a few
billions of years ago. The book discusses why dark energy must
exist and what its existence implies, especially for the future and
the end of our Universe.
This monograph develops an innovative approach that utilizes the
Birman-Schwinger principle from quantum mechanics to investigate
stability properties of steady state solutions in galactic
dynamics. The opening chapters lay the framework for the main
result through detailed treatments of nonrelativistic galactic
dynamics and the Vlasov-Poisson system, the Antonov stability
estimate, and the period function $T_1$. Then, as the main
application, the Birman-Schwinger type principle is used to
characterize in which cases the "best constant" in the Antonov
stability estimate is attained. The final two chapters consider the
relation to the Guo-Lin operator and invariance properties for the
Vlasov-Poisson system, respectively. Several appendices are also
included that cover necessary background material, such as
spherically symmetric models, action-angle variables, relevant
function spaces and operators, and some aspects of Kato-Rellich
perturbation theory. A Birman-Schwinger Principle in Galactic
Dynamics will be of interest to researchers in galactic dynamics,
kinetic theory, and various aspects of quantum mechanics, as well
as those in related areas of mathematical physics and applied
mathematics.
This book provides a guide to engineering successful and reliable
products for the NewSpace industry. By discussing both the
challenges involved in designing technical artefacts, and the
challenges of growing an organisation, the book presents a unique
approach to the topic. New Space Systems Engineering explores
numerous difficulties encountered when designing a space system
from scratch on limited budgets, non-existing processes, and great
deal of organizational fluidity and emergence. It combines
technical topics related to design, such as system requirements,
modular architectures, and system integration, with topics related
to organizational design, complexity, systems thinking, design
thinking and a model based systems engineering. Its integrated
approach mean this book will be of interest to researchers,
engineers, investors, and early-stage space companies alike. It
will help New Space founders and professionals develop their
technologies and business practices, leading to more robust
companies and engineering development.
A glass is disordered material like a viscous liquid and behaves
mechanically like a solid. A glass is normally formed by
supercooling the viscous liquid fast enough to avoid
crystallization, and the liquid-glass transition occurs in diverse
manners depending on the materials, their history, and the
supercooling processes, among other factors. The glass transition
in colloids, molecular systems, and polymers is studied worldwide.
This book presents a unified theory of the liquid-glass transition
on the basis of the two band model from statistical quantum field
theory associated with the temperature Green's function method. It
is firmly original in its approach and will be of interest to
researchers and students specializing in the glass transition
across the physical sciences.
Visual Astronomy introduces the basics of observational astronomy,
a fundamentally limitless opportunity to learn about the universe
with your unaided eyes or with tools such as binoculars,
telescopes, or cameras.
Everyone knows that there are things no one can see, for
example, the air you're breathing or a black hole, to be more
exotic. But not everyone knows that what we can see makes up only 5
percent of the Universe. The rest is totally invisible to us.
The invisible stuff comes in two varieties--dark matter and
dark energy. One holds the Universe together while the other tears
it apart. What these forces really are has been a mystery for as
long as anyone has suspected they were there, but the latest
discoveries of experimental physics have brought us closer to that
knowledge. Particle physicist Dan Hooper takes his readers, with
wit, grace, and a keen knack for explaining the toughest ideas
science has to offer, on a quest few would ever have expected: to
discover what makes up our dark cosmos.
Structure and Evolution of Single Stars: An introduction is
intended for upper-level undergraduates and beginning graduates
with a background in physics. Following a brief overview of the
background observational material, the basic equations describing
the structure and evolution of single stars are derived. The
relevant physical processes, which include the equation of state,
opacity, nuclear reactions and neutrino losses are then reviewed.
Subsequent chapters describe the evolution of low-mass stars from
formation to the final white dwarf phase. The final chapter deals
with the evolution of massive stars.
