Foundations of Astrophysics

Astrophysics is a specialized branch of astronomy that applies the principles of physics and chemistry to explore the intrinsic nature of astronomical objects, focusing on their fundamental properties rather than just their positions or motion in space. This field explores a wide range of celestial bodies, including stars, galaxies, extrasolar planets, and the cosmic microwave background. Astrophysics seeks to determine key attributes of these objects--such as luminosity, density, temperature, chemical composition, and emitted radiation. The field is majorly divided into two main areas: observational astrophysics, which focuses on collecting and analyzing observational data, and theoretical astrophysics, which uses physical models to explain observable phenomena. This book provides comprehensive insights into the field of astrophysics. The various sub-fields along with technological progress that have future implications are glanced at. The book is appropriate for those seeking detailed information in this area.
