Effects of planetary day-night temperature gradients on He 1083 nm transit spectra
Fabienne Nail, Antonija Oklopčić, Morgan MacLeod
A notable fraction of helium observations probing the evaporating atmospheres of short-period gas giants at 1083~nm exhibit a blueshift during transit, which might be indicative of…
