INTRODUCTION
INTRODUCTION
The goal of this book is to frame astrophysics as a scientific discipline in its own right.
Often squeezed between astronomy and cosmology, astrophysics, i.e. the physical study of celestial objects, runs the risk of becoming a kind of chapter in these sectors.
Instead, it has quite special characteristics.
Unlike astronomy, it doesn't just catalog and be descriptive, it probes the inner workings of stellar and galactic functioning.
Unlike cosmology or the study of black holes, it investigates neither the origins of the Universe nor global or singular spacetime.
Obviously, astrophysics owes a lot to these disciplines and it is for this reason that the first chapter of this book (and partly also the last) will have a purely astronomical descriptive character.
As for the points of contact with cosmology, only a brief hint is given during the exposition of stellar and galactic evolution.
For the rest, the book focuses on the main celestial objects, especially stars and galaxies, probing their equations, the physical and chemical processes that govern them.
To understand what is stated, it is not necessary to know the general theory of relativity (as is the case for cosmology), but it is enough to have a smattering of classical physics, at least at the university level.
Even a knowledge, albeit limited, of nuclear and particle physics would not be disdainful, since the nuclear processes that take place in stars are very similar to what we try to reproduce in particle accelerators present in laboratories around the world.

THE SOLAR SYSTEM
THE SOLAR SYSTEM
The planet we live on, the Earth, is located within a planetary system that surrounds a star, called the Sun.
The mass of this star makes up 99.9% of the total mass of the solar system.
