The effects of stellar activity cycles on planetary atmospheric escape and the HeI 1083nm transit signature
Andrew P. Allan, Aline A. Vidotto, Jorge Sanz-Forcada +1
The HeI 1083nm transit signature is commonly used in tracing escaping planetary atmospheres. However, it can be affected by stellar activity, complicating detections and interpreta…
Helium escape signatures are generally strongest during younger ages but this age dependence is lost in the diversity of observed exoplanets
Andrew P. Allan, Aline A. Vidotto
Highly irradiated exoplanets undergo extreme hydrodynamic atmospheric escape, due to their high level of received XUV flux. Over their lifetime, this escape varies significantly, m…
Non-Detections of Helium in the Young Sub-Jovian Planets K2-100b, HD 63433b, & V1298 Tau c
Munazza K. Alam, James Kirk, Leonardo A. Dos Santos +10
We search for excess in-transit absorption of neutral helium at 1.083 m in the atmospheres of the young (<800 Myr) sub-Jovian (0.2-0.5 ) planets HD 63433b, K2-100b, a…
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 metastab…
