The planck mass and the chandrasekhar limit
Webb20 feb. 2015 · 6. Chandrasekhar's most notable work was the astrophysical Chandrasekhar limit. The limit describes the maximum mass of a white dwarf star, ~1.44 solar masses, or equivalently, the minimum mass which must be exceeded for a star to ultimately collapse into a neutron star or black hole . Webb25 mars 2024 · The Chandrasekhar limit (tndrekr) is the maximum mass of a stable white dwarf star. The limit was first indicated in papers published by Wilhelm Anderson and E. C. Stoner, and was named after Subrahmanyan Chandrasekhar, the Indian astrophysicist who independently discovered and improved upo

DB said: 299 792/617 km/s = approx. 485.88, so now if a mass of 1.989 e30 kg has an escape velocity of 617 km/s then: 1.989 e30 kg x 485.88 = 9.66 e32 kg (a pretty much exact mass of an object that can barely emit light.)

Webb10 apr. 2024 · Your understanding is more-or-less right about the Chandrasekhar mass. The maximum mass is likely to be a little lower than $1.4 M_{\odot}$ because collapse or explosion may be triggered by either General Relativistic instabilities, inverse beta decay or by pyconuclear reactions, that all commence when the (central) density reaches $\sim …
