Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron—less than 1/40,000th of the sun.
Red dwarfs make up the vast majority of stars in the galaxy. Such ubiquity means they host the majority of rocky exoplanets ...
In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the ...

Could Dyson spheres exist around red dwarf stars? Study explores where astronomers might find them
Researchers explore Dyson spheres around red dwarf stars, detailing infrared signatures, equilibrium temperatures, and ...
This artist’s impression shows a sunset seen from the super-Earth Gliese 667 Cc. Astronomers have estimated that there are tens of billions of such rocky worlds orbiting faint red dwarf stars in the ...
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, ...
That thinning likely resulted from two stars merging and burning off outer layers during the collision. This rare white dwarf merger left a stripped remnant with a nearly pure hydrogen atmosphere yet ...
