RX J0648.0–4418 is a shrinking white dwarf star spinning every 13 seconds The star gains mass from its companion, nearing the Chandrasekhar limit This binary system may witness a supernova explosion ...

Simulations have shown that while the primary white dwarf can explode, the secondary may not always ignite, leading to different observable characteristics in the resulting supernova[5].

SN 2024PI is special because it's classified as a Type Ia supernova. A white dwarf, which is an incredibly dense, small "dead" star (about the size of a planet), must exist before this special ...

The SN 1181 remnant is not the usual supernova remnant. It has a “zombie star” at its heart. This is a dense, dead star called a white dwarf that triggers a thermonuclear explosion resulting in a ...

Using the Gran Telescopio Canarias (GTC) and the Apache Point Observatory (APO), an international team of astronomers has detected 19 pulsation modes in an ultra-massive white dwarf known as WD ...
