Stars and Stellar Evolution

In this lesson, we will be exploring the characteristics of stars, their life cycles and the evolutionary processes that shape them. We will start by looking at the different characteristics of stars, including size, mass, temperature and luminosity. Then, we will delve into the Hertzsprung-Russell diagram, an important tool in understanding the properties of stars and their evolutionary stages. We will also discuss spectral classification and how it is used to understand the composition and temperature of stars. Furthermore, we will explore the different classification of stars and the life cycle of stars, including the birth, main sequence, red giant, and supernova stages.
