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.
