With so much of our current understanding of the universe based on Type 1a supernovae data, a good deal of current research is focused upon just how standard these supposed standard candles are. To date, the weight of analysis ...

(PhysOrg.com) -- Astronomers have turned up the first direct proof that "standard candles" used to illuminate the size of the universe, termed Cepheids, shrink in mass, making them not quite as standard as once thought. The ...

For all their enormous size and furious energies, stars are remarkably simple. Knowing just their mass and the smattering of elements heavier than hydrogen we can predict their lives from cradles to grave. But every now and ...

Type Ia supernovae happen when a white dwarf, the "corpse" of a star similar to the Sun, absorbs material from a twin star until it reaches a critical mass—1.4 times that of the Sun—and explodes. Because of their origin, ...

The research group from the University of Tokyo and Keio University discovered that a Type Ia supernova occurs after its companion star evolves into a faint helium white dwarf in many cases, given the fact that the white ...
