Evolution of helium triplet transits of close-in gas giants orbiting K-dwarfs
Andrew P. Allan, Aline A. Vidotto, Carolina Villarreal D'Angelo +2
Atmospheric escape in exoplanets has traditionally been observed using hydrogen Lyman- and H- transmission spectroscopy, but more recent detections have utilised the metast…
