Mass lower limit of white dwarf

Webthe relationship between their Radius and total Mass and as a final result, the limit mass known as the Chandrasekhar Mass. Founded by Subrahmanyan Chandrasekhar in the early 30’s this limit mass of about 1.4MJ became fun-damental for the understanding of the final stages of massive stars and gave a glimpse over new fields of astrophysics. 1.
