Astrophysics (ePub)

This book describes how physics and chemistry are used in
process of determining nature of various astronomical objects.
Celestial mechanics describes how physics is applied in order to
determine the positions and motions of astronomical objects.
Described studies related to large scale structures of the
universe are described in physical cosmology. However, they are
not a part of astrophysics. In astrophysics it is described how
chemistry and physics are applied to figure out the nature of
certain astronomical objects. Astrophysics is a branch of
astronomy (
Astronomy + Physics = Astrophysics). Various
principles from physics and chemistry are described in
astrophysics. These principles are useful in ascertaining the
nature of heavenly bodies, instead of their positions or motion
behavior. Following objects are studied under this particular
field:
Sun
Stars
Galaxies
Extrasolar planets
Interstellar medium
Cosmic microwave
Background
Many things related to this field and their area of studies
would be described in this book. It is going to be short and
sweet even multiple books are not enough to cover whole
concept of astrophysics at once. Book will start by describing
the history of astrophysics. In the history, all important names,
foundation of basic concepts would be covered. It will really be
helpful for fresher since all basic concepts would be described
and explained well. Astrophysics are usually learned or studied
in two categories or sectors. First one is observational
astrophysics and second one is theoretical astrophysics. Both of
them are equally important since theoretical knowledge is
important when one tries to apply these concepts practically. In
the same way, there is not meaning of learning theories that
has no use in practical implementation. In this book, both
sectors are described in individual chapters. In those chapters,
each important concept of these two sectors will be covered.
Popularization is another important concept of astrophysics. It is
also covered in a separate chapter. Overall, this book is a
complete package for understanding basic concepts of
astrophysics. Despite of this basic tag, these concepts are not
that easy to understand since astrophysics is a hybrid concept
of astronomy and physics.
