Astronomers using NASA's TESS data discovered a red dwarf star with a big gas giant exoplanet, defying planet formation theories.

CW Leonis, a massive red giant star, is in the final throes of its life, undergoing a violent transformation as it nears the end of its stellar life cycle. Located in the constellation Leo, this star ...

Well, it might be a binary white dwarf system—fast-spinning white dwarfs are sometimes found locked in binary systems with other low-mass stars.

A giant exoplanet is surprisingly chill given how close it is to its red dwarf star — perhaps because the star is so little.

That bodes poorly for the existence of long-term life on exoplanets orbiting red dwarfs, which also happen to be the most plentiful type of star.

The TRAPPIST-1 system is a science-fiction writer’s dream. Seven Earth-sized worlds orbit a red dwarf star just 40 light-years away. Three of those worlds are within the habitable zone of the star.

No type of star is as common in the cosmos as red dwarfs, but the conditions there are harsh for exoplanets. Nevertheless, some could probably hold atmospheres.
