The Impact Of Stellar Flares On The Atmospheric Escape of Exoplanets Orbiting M stars I: Insights From The AU Mic System
The X-rays and Extreme Ultraviolet (XUV) emission from M stars can drive the atmospheric escape on planets orbiting them. M stars are also known for their frequent emission of stellar […]

Superflares Are Less Harmful To Exoplanets Than Previously Thought
Superflares, extreme radiation bursts from stars, have been suspected of causing lasting damage to the atmospheres and thus habitability of exoplanets. A newly published study found evidence that they only […]

Effect Of Stellar Flares on Planetary Habitability
Scientists funded in part by the NASA Astrobiology program are providing new insights into how terrestrial planets are affected by coronal mass ejections (CMEs) early in the formation of a […]
