Results of the new observations, published April 9 on the arXiv preprint server, indicate that the system harbors a massive pulsating white dwarf. Cataclysmic variables (CVs) are binary star ...

White dwarf pair likely to become Type 1a supernova Stars orbit each other in 14 hours, tightening over time Supernova will aid cosmic distance measurements ...

WASHINGTON, April 8 — Astronomers have spotted two hefty white dwarf stars - highly compact stellar embers - orbiting close together that appear destined to die in an extraordinarily violent quadruple ...

Compact objects other than neutron stars are capable of producing bright radio emission.

Studying them helps scientists understand how stars like our sun evolve and die. Astronomers know that some white dwarf binaries (a pair of stars orbiting each other) develop magnetic fields and some ...

In this picture, we capture the binary in the moment where the first white dwarf has just exploded, hurtling material towards its nearby companion which is on the cusp of explosion too. This event ...

One white dwarf will siphon matter off the other, triggering a rare “1a” supernova with four separate explosions. The growing white dwarf will first explode at the point where it is gathering ...

If experts know how bright something should be, and they measure how bright it appears, they can determine out how far away it is. These explosions happen when a white dwarf, which is already an ultra ...

That capability sets the stage for fresh computer experiments comparing two very different star systems. After a Sun‑like star sheds its outer layers, its core contracts into a white dwarf that is ...
