Magnetic Interaction of Stellar Coronal Mass Ejections with Close-in Exoplanets: Implication on Planetary Mass Loss and Ly-α Transits
Coronal Mass Ejections (CMEs) erupting from the host star are expected to have effects on the atmospheric erosion processes of the orbiting planets. For planets with a magnetosphere, the embedded […]
