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…

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…

Fully scalable forward model grid of exoplanet transmission spectra

Jayesh M. Goyal, Hannah R. Wakeford, Nathan J. Mayne +3

Simulated exoplanet transmission spectra are critical for planning and interpretation of observations and to explore the sensitivity of spectral features to atmospheric thermochemi…

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…

The 3D thermal, dynamical and chemical structure of the atmosphere of HD 189733b: implications of wind-driven chemistry for the emission phase curve

Benjamin Drummond, Nathan J. Mayne, James Manners +5

In this paper we present three-dimensional atmospheric simulations of the hot Jupiter HD~189733b under two different scenarios: local chemical equilibrium and including advection o…
