Chandrasekhar is a key concept in the study of stellar evolution, particularly the transition from the main sequence to the red giant stage. It refers to the work of the Indian astrophysicist Subrahmanyan Chandrasekhar, who made significant contributions to our understanding of the physical processes that govern the fate of stars as they age. Chandrasekhar's research focused on the maximum mass a star can have and still remain stable as a white dwarf, a dense remnant of a star that has exhausted its nuclear fuel. This critical mass, now known as the Chandrasekhar limit, is a crucial factor in determining the evolutionary path of a star and its ultimate fate.
congrats on reading the definition of Chandrasekhar. now let's actually learn it.
