A supernova is one way that a star can end its life, ... The crucial question is thus to know whether the white dwarf can manage to gain weight despite the outburst, that is, if some of the matter taken from the companion stays on the white dwarf, so that it will eventually become heavy enough to explode as a supernova.

ESA’s XMM-Newton orbiting X-ray telescope has uncovered the first close-up of a white dwarf star that could explode into a type Ia supernova within a few million years. ... Most likely, the white dwarf has grown to its unusual mass by stealing gas from its companion star, a process known ... I meant a Supernovae Type 1 !!

The "Type I" supernovae arise when the white dwarf star member of a binary system accretes so much matter from its companion that it is tipped over the 1.4M Chandrasekar limit. ... 1) If the core which remains has a mass <~3M , it will become a neutron star/pulsar like the Crab pulsar. ... binary system evolving to type I supernova...

When gas become super-compressed, particles bump right up against ... White dwarfs form as the outer layers of a low-mass red giant star puff out to make a planetary nebula. Since the lower mass stars make the white dwarfs, this type of remnant is the most common endpoint for stellar evolution. ... Novae and Supernovae Type I...

Because the overwhelming majority of stars in the universe — including the Sun — will end their lives as white dwarfs, studying the pulsations (i.e., ... Last year, University of Arizona astronomers Patrick Dufour and James Liebert discovered a third type of white dwarf star, still more rare. For reasons that are...

A rare new kind of star may have been discovered. It is much like the white dwarf our own sun should eventually become—save for a mysterious shroud of carbon ash. ...

ESA’s XMM-Newton orbiting X-ray telescope has uncovered a celestial Rosetta stone: the first close-up of a white dwarf star, circling a companion star, that could explode into a particular kind of supernova in a few million years. ... The explosion of a white dwarf is the leading explanation for type Ia supernovae,

Supernovae are classified as Type I if their light curves exhibit sharp maxima and then die away smoothly and gradually. The model for the initiation of a Type I supernova is the detonation of a carbon white dwarf when it collapses under the pressure of electron degeneracy.

White dwarf supernovae ... They quite likely overlap the masses of planets. Planets are by current definition made from the "bottom up," accumulated from dust in disks surrounding new stars, while stars (including brown dwarfs) are made from the "top ... But here even the definitions become confused and might overlap as well.
