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 ...

Using NASA’s IXPE, astronomers captured an unprecedented view of a white dwarf star actively feeding on material from a companion. The data revealed giant columns of ultra-hot gas shaped by the star’s ...

ASKAP J1832-0911 is a long-period radio transient (LPT) object, which emits radio waves in periods of tens of minutes. But it is also the first LPT known to emit X-rays. This mysterious object could ...

NASA’s IXPE captures the first X-ray polarization data from a white dwarf system, detailing observations of EX Hydrae and ...

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, ...

NASA’s IXPE has become the first observatory to measure a white dwarf star. It used its X-Ray polarization to reveal the ...

This artist’s concept depicts a smaller white dwarf star pulling material from a larger star, right, into an accretion disk.

Pulsars are highly magnetised, rotating neutron stars that emit beams of radiation detectable from Earth, while many pulsars coexist in binary systems with companion stars. In these systems, the ...

Astronomers have traced the origin of a colossal white dwarf to a catastrophic crash between two dead stars, turning a quiet ...

"The diversity of ways that white dwarf stars can blow up is much greater than previously expected." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

There are a lot of ways for dead stars to blow their tops. Astronomers discovered this explosive diversity when they assessed ...
