NYUAD study finds stellar flares can lead to the diminishment of a planet's habitability

In a new study, a team led by research scientist Dimitra Atri of the Center for Space Science at NYU Abu Dhabi (NYUAD) identified which stars are most likely to host habitable exoplanets based on the calculated erosion rates of the planetary atmospheres.

In the paper titled “Stellar flares versus luminosity: XUV-induced atmospheric escape and planetary habitability,” published in the journal Monthly Notices of Royal Astronomical Society: Letters, Atri and graduate student Shane Carberry Mogan have presented the process of analyzing flare emission data from NASA’s Transiting Exoplanet Survey
