https://doi.org/10.1007/978-1-4302-0086-4We have so far covered topics that describe how a star forms, how the mass of stars can be determined by observing binary-star systems, and how long it takes to become a star. Now we shall discuss how long a star will remain on the main sequence and then look at what happens due to changes in its internal structure.
