Until now, important research on the historical records of comets
and meteor showers from China, Japan, and Korea has remained the
exclusive preserve of those with expertise in the relevant
languages. With a compilation like the present volume the authors
hope to ameliorate that situation. Applying the same rigorous
selection criteria and style of presentation as in the previous
catalogue, assembled and translated here are some 1,500 additional
observations of comets and meteor showers from China, Japan, and
Korea spanning nearly three millennia. With the publication of this
volume, most of the important historical records of East Asian
astronomical observations are now accessible in English. The
introductions and appendices provide all the required information
on specialized terminology, recording conventions, and nomenclature
the reader will need to make use of the records. In addition to
being an invaluable resource for professional astronomers, East
Asian astronomical records have materially aided the research of
scholars in fields as diverse as mythology, medieval iconography,
ancient chronology, and the oral history of pre-literate societies.
The book should be of great interest to cultural astronomers, as
well as to those engaged in historical and comparative research.
This book reports on the extraordinary observation of TeV gamma
rays from the Crab Pulsar, the most energetic light ever detected
from this type of object. It presents detailed information on the
painstaking analysis of the unprecedentedly large dataset from the
MAGIC telescopes, and comprehensively discusses the implications of
pulsed TeV gamma rays for state-of-the-art pulsar emission models.
Using these results, the book subsequently explores new testing
methodologies for Lorentz Invariance Violation, in terms of a
wavelength-dependent speed of light. The book also covers an
updated search for Very-High-Energy (VHE), >100 GeV, emissions
from millisecond pulsars using the Large Area Telescope on board
the Fermi satellite, as well as a study on the promising Pulsar
Wind Nebula candidate PSR J0631. The observation of VHE gamma rays
is essential to studying the non-thermal sources of radiation in
our Universe. Rotating neutron stars, also known as pulsars, are an
extreme source class known to emit VHE gamma rays. However, to date
only two pulsars have been detected with emissions above 100 GeV,
and our understanding of their emission mechanism is still lacking.
This book includes the proceedings of the conference "Problems of
the Geocosmos" held by the Earth Physics Department, St. Petersburg
State University, Russia, every two years since 1996. Covering a
broad range of topics in solid Earth physics and solar-terrestrial
physics, as well as more applied subjects such as engineering
geology and ecology, the book reviews the latest research in
planetary geophysics, focusing on the interaction between the
Earth's shells and the near-Earth space in a unified system. This
book is divided into four sections: * Exploration and Environmental
Geophysics (EG), which covers two broad areas of environmental and
engineering geophysics - near-surface research and deep geoelectric
studies; * Paleomagnetism and Rock Magnetism (P), which includes
research on magnetostratigraphy, paleomagnetism applied to
tectonics, environmental magnetism, and marine magnetic anomalies;
* Seismology (S), which covers the theory of seismic wave
propagation, Earth's structure from seismic data, global and
regional seismicity and sources of earthquakes, and novel seismic
instruments and data processing methods; and * Physics of
Solar-Terrestrial Connections (STP), which includes magnetospheric
phenomena, space weather, and the interrelationship between solar
activity and climate.
This book presents a global and synthetic vision of planetology -
the study of objects in the Solar System. In the past several
decades, planetology has undergone a real revolution, marked in
particular by the discovery of the Kuiper belt beyond Neptune, the
discovery of extrasolar planets, and also by the space exploration
of ever more distant objects. Today, it is at the crossroads of
many disciplines: astronomy, geophysics, geochemistry and biology.
The Solar System 1 deals with the Solar System as a whole, offering
a general presentation of the objects that compose it and its place
in the galaxy. It also deals with planetary systems, exoplanets and
the interaction of Solar System objects with interplanetary medium.
Finally, it analyzes the telluric and giant planets.
The only small, popular book on the important subject of ancient
calendars.
The study of heavenly cycles is common to most ancient cultures.
The ancient Egyptians, Chinese, and Babylonians all tried to make
sense of the year. But it fell to the later Mesoamerican Maya to
create a series of calendars that could be cross referenced. In
doing so, the Maya discovered many strange numerical harmonics.
Their lunar calendar was extremely accurate--far more so than the
Greek Metonic cycle; they tracked Venus to an accuracy of less than
a day in five hundred years and their tables could have been used
to predict eclipses seven hundred years in the future. This book
will provide a much needed compact guide to the Mayan calendar
systems as well as covering the essentials of calendar development
throughout the world.
