Hubble PanCET: An extended upper atmosphere of neutral hydrogen around the warm Neptune GJ 3470 b
V. Bourrier, A. Lecavelier des Etangs, D. Ehrenreich +16
GJ 3470b is a warm Neptune transiting an M-dwarf star at the edge of the evaporation desert. It offers the possibility of investigating how low-mass, close-in exoplanets evolve und…
Spectrally resolved helium absorption from the extended atmosphere of a warm Neptune-mass exoplanet
R. Allart, V. Bourrier, C. Lovis +7
Stellar heating causes atmospheres of close-in exoplanets to expand and escape. These extended atmospheres are difficult to observe because their main spectral signature - neutral…
Observability of hydrogen-rich exospheres in Earth-like exoplanets
Leonardo A. dos Santos, Vincent Bourrier, David Ehrenreich +1
(Abridged) The existence of an extended neutral hydrogen exosphere around small planets can be used as an evidence for the presence of water in their lower atmosphere but, to date,…
The HST PanCET Program: Hints of Na I & Evidence of a Cloudy Atmosphere for the Inflated Hot Jupiter WASP-52b
Munazza K. Alam, Nikolay Nikolov, Mercedes Lopez-Morales +16
We present an optical to near-infrared transmission spectrum of the inflated hot Jupiter WASP-52b using three transit observations from the Space Telescope Imaging Spectrograph (ST…
WASP-166b: a bloated super-Neptune transiting a V = 9 star
Coel Hellier, D. R. Anderson, A. H. M. J. Triaud +21
We report the discovery of WASP-166b, a super-Neptune planet with a mass of 0.1 Mjup (1.9 Mnep) and a bloated radius of 0.63 Rjup. It transits a V = 9.36, F9V star in a 5.44-d orbi…
An optical transmission spectrum for the ultra-hot Jupiter WASP-121b measured with the Hubble Space Telescope
Thomas M. Evans, David K. Sing, Jayesh Goyal +24
We present an atmospheric transmission spectrum for the ultra-hot Jupiter WASP-121b, measured using the Space Telescope Imaging Spectrograph (STIS) onboard the Hubble Space Telesco…
