Dealing with astrophysics derived from the radiation emitted by
radioactive atomic nuclei, this book describes the different
methods used to measure cosmic radio-isotopes. It demonstrates how
this astronomical window has contributed to the understanding of
the sources and the chemical evolution of cosmic gas. Reference
materials and explanations are included for students in advanced
stages of their education. Nuclear reactions in different sites
across the universe lead to the production of stable and unstable
nuclei. Their abundances can be measured through different methods,
allowing to study the various nuclear processes taking place in
cosmic environments. Nucleosynthesis is the cosmic formation of new
nuclear species, starting from hydrogen and helium resulting from
the big bang origins. Stars create and eject synthesized nuclei
during their evolution and explosions. Incorporation of the new
interstellar composition into next-generation stars characterises
the compositional (chemical) evolution of cosmic gas in and between
galaxies. Radioactive species have unique messages about how this
occurs. Since the first Edition of this book published in 2011 with
the title Astronomy with Radioactivities, long-awaited new direct
observations of supernova radioactivity have been made and are now
addressed in two updated chapters dealing with supernovae. In this
second Edition, the advances of recent years beyond one-dimensional
treatments of stellar structure and stellar explosions towards
3-dimensional models have been included, and led to significant
re-writings in Chapters 3-5. The sections on the Solar System
origins have been re-written to account for new insights into the
evolution of giant molecular clouds. The chapter on diffuse
radioactivities now also includes material measurements of
radioactivities in the current solar system, and their
interpretations for recent nucleosynthesis activity in our Galaxy.
Significant new results on gamma-rays from positron annihilations
have been accounted for in that chapter, and led to new links with
nucleosynthesis sources as well as interstellar transport
processes. A new chapter now provides a description of interstellar
processes often called 'chemical evolution', thus linking the
creation of new nuclei to their abundance observations in gas and
stars. The experimental / instrumental chapters on nuclear reaction
measurements, on gamma-ray telescopes, and pre-solar grain
laboratories have been updated. Moreover, new windows of astronomy
that have been opened up in recent years have been included in the
discussions of the multi-messenger approach that broadens the basis
for astrophysical insights.
