The Physics of Stars and Their Astronomical Identification

ABSTRACT

In this study of the physics of stars and their astronomical identification, It is evident that stars undergo certain physical processes as they live through their life cycle.

How gravity, magnetic field and nuclear fusion play a role in stellar evolution is explained extensively. This research describes the structure and evolution of stars.

The structure and evolution of a star is determined by the laws of Hydrostatic equilibrium, energy transport and generation and conservation of energy while the mass of the star is the governing factor in the evolution and structure of the star and determines its properties.

Also, stellar spectra is discussed in this work. Different elements absorb different wavelengths of light. The spectrum of a star lets us know what elements are in the star.

Finally, stars and how they are identified astronomically is also discussed as different stars have different astronomical identification.

INTRODUCTION

The study of stars is of very crucial value in astronomy as the stars are a fundamental unit of galaxies, which are very important building blocks of the universe.

The physics of this stars is a relevant area that needs to be covered in order to uncover what causes stars to behave the way they behave when they are formed, during their life time and when they die.

The structure and evolution of a star is determined by the laws of Hydrostatic equilibrium, energy transport and generation and conservation of energy.

The mass of the star is the governing factor in the evolution and structure of the star and determines its properties.

This study will enable one to understand the physical science behind the life cycle of stars and their astronomical identification, as it covers the physical processes (Hydrostatic equilibrium, conservation of energy, energy transport) that occur during their lifetime. The basic units of luminous matter in the whole universe are the stars.

A star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). It is therefore important to study and to know the astrophysics behind the formation, the life, the explosion or death of stars and also their astronomical identification and properties.
