About 8,150 light-years from Earth, a white dwarf star named Gaia22ayj has intrigued astronomers. Its unusual behavior, ...

The hunt for habitable planets beyond the Solar System just became more difficult. A study posted today on the arXiv server suggests that the same factors that make planets near M-dwarf stars easy ...

Solar flares can reshape exoplanet atmospheres within days, affecting temperature, winds, and potential habitability.

A new article describes the detrimental impact of stellar wind on the atmosphere of exoplanets.

Astronomers have discovered the "missing link" connecting the death of sunlike stars to the birth of white dwarf stellar remnants, in the form of a "teenage vampire" white dwarf.

Astronomers have discovered a record-breaking burst of energy coming from deep space, tracing it to a binary system containing a tiny red dwarf star and a dead stellar remnant called a white dwarf.

A celestial object discovered decades ago is actually twins orbiting each other, a new study confirms. Scientists have puzzled over the object known as Gliese 229B, the first known brown dwarf ...

An international team of astronomers reports the discovery of a new giant exoplanet around an M-dwarf star (GEMS). The newfound GEMS, designated TOI-5573 b, is comparable in size to Saturn and its ...

Typically, this rapid stream of particles astronomers call stellar wind should blow off from the white dwarf as a by-product of the star’s fast spinning right after the supernova explosion.

Hubble has homed in on a nearby star called R Aquarii, which is throwing out material for billions of miles around it.

However, this merger left behind a white dwarf. The spinning white dwarf was expected to create a stellar wind (a fast-flowing stream of particles) immediately after its formation.
