New model explains how inspiraling dead stars can explode at a rate high enough to match the number of Type Ia supernovae seen in universe A new mathematical model created by astrophysicists at the ...

Study models how an ultra-compact double white dwarf binary ends
Researchers have used stellar evolution simulations to trace the future of ATLAS J1138-5139, an ultra-compact double white ...
Astronomers have found a remarkable pair of stars that may finally prove a long-debated theory. Described in the journal Nature Astronomy, this duo offers the strongest evidence yet that type 1a ...
Type Ia supernovae are critical tools in astronomy, since they all appear to explode with the same intensity, allowing us to use their brightness as a measure of distance. The distance measures ...
Type Ia supernovae represent the dramatic thermonuclear explosions of white dwarf stars, typically triggered in binary systems by processes such as accretion from a companion or the merger of two ...
The future of yellow dwarf stars, like our sun, is determined almost entirely by their mass. The most massive stars, about eight to 12 times heftier than the sun, can explode as supernovae, leading to ...
Add Yahoo as a preferred source to see more of our stories on Google. This image, taken with ESO’s Very Large Telescope (VLT), shows the supernova remnant SNR 0509-67.5. These are the expanding ...

2 isolated dead stars emit X-rays that defy current models
Two isolated white dwarfs, each lacking the companion star that conventional astrophysics says should fuel high-energy ...
Stars often die with a final burst of beauty. For the first time, astronomers have captured visual proof that a star can explode not once, but twice before fading forever. Using the European Southern ...
White dwarf stars represent the evolutionary endpoints of medium- and low-mass stars, comprising the dense, electron-degenerate cores left after nuclear fuel exhaustion. In binary systems, ...
A burst of X-rays from 8 billion years ago may be the first clear evidence of a white dwarf torn apart by a black hole. "Our computational simulations show that the combination of the tidal forces of ...
