Addition: With a mass of 1.02 M☉, Sirius B is estimated at 5 M☉ during its main-sequence. Formula: T=(M/L)*10k(where k is the percentage of H in mass that can be burnt dring main-sequence) Roche: r1/A=(0.49q^(2/3))/(0.6q^(2/3)+ln(1+q(^1/3))) (where q=M1/M2) Sirius A will lose 1.4 M☉ during the Red Giant period. However, Sirius B is unlikely to transform into a type-1a supernova due to its distance to Sirius A. The key uncertainties are the speed at which mass is lost from the giant Sirius A, whether the material that lands on the white dwarf explodes on contact, and whether enough mass can be collected by the white dwarf to get close to the Chandrasekhar limit. In order to explode as a supernova, the white dwarf must increase its mass to close to 1.4 times the mass of the Sun, known as the Chandrasekhar limit. It seems unlikely that it will be able to do this unless the wind from the AGB star is even slower than expected, especially as the orbit of the two stars will widen(oops I forgot) as mass escapes from the system as a whole. Even if the white dwarf were to capture this much mass. --https://astronomy.com/magazine/ask-as... 39.
