Overview

Analysis reveals that M-dwarf flares have limited influence on atmospheric evaporation in sub-Neptunes and Earth-sized planets.

Key Points

  • Flares lead to less than a factor of 2 increase in atmospheric mass loss, when planets are nearest to the star.
  • Relative mass loss is greater for planets at larger orbital separations during flaring events and during quiescence.
  • Employing photoionization hydrodynamics, our analysis captures the dynamics of atmospheric escape under varying flare activity.
  • Characteristic flare energy maximizes the fractional contribution to flare-driven mass loss for affected planets.
