Since the Chandrasekhar limit is always at 1.4 solar masses, this would explain why Type Ia supernovae always have the same ...

Astronomers have long predicted that two orbiting white dwarfs are the cause of most type 1a supernova explosions. While the pair are in close orbit, the heavier of the two theoretically accumulates ...

"Discovering that the two stars are separated by just 1/60th of the Earth-Sun distance, I quickly realised that we had discovered the first double white dwarf binary that will undoubtedly lead to a ...

Type Ia supernovae originate in binary star systems—systems where two stars orbit each other. In one possible scenario, there are two stars approximately the same size—let's say about the size ...

Using the Hubble Space Telescope and an array of other instruments, astronomers have probed supernova wreckage in the Large ...

The white dwarfs have a combined mass of around 1.56 times the sun's mass — a ... dwarf binary that will undoubtedly lead to a type 1a supernova." Simulations show how the supernova's multiple ...

Supernovae are divided into two basic physical types, Ia and II. Type Ia is caused by thermal runaway, and type II supernovae are caused by core collapse. Because the supernova "family tree" was ...

Using the Australia Telescope Compact Array (ATCA) and Parkes 64-m telescope, an international team of astronomers has ...

Washington resident Jeff Thornburg has an impressive and lengthy resume, and now his company has a new type of space vehicle: The Supernova.

A pair of white dwarfs, located just 150 light-years from Earth, appears doomed to die in a type 1a supernova that will shine brighter than anything currently visible in the night sky. But ...

"A Type Ia supernova occurs when a white dwarf in a binary ... As this material accumulates on the white dwarf, the dead star's mass approaches 1.4 times that of the sun, the so-called ...
