Astrophysics is
the branch of astronomy that employs the principles of physics and chemistry
"to ascertain the nature of the heavenly bodies, rather than their
positions or motions in space." Among the objects studied are the Sun,
other stars, galaxies, extrasolar planets, the interstellar medium and the
cosmic microwave background. Astrophysics is a very broad subject;
astrophysicists typically apply many disciplines of physics, including
mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum
mechanics, relativity, nuclear and particle physics, and atomic and molecular
physics.
In the present
book, fifteen typical literatures about Astrophysics published on
international authoritative journals were selected to introduce the worldwide
newest progress, which contains reviews or original researches
on electrodynamics, astronomy, cosmology, ect. We hope
this book can demonstrate advances in Astrophysics as well as give
references to the researchers, students and other related people.
