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…
Revisiting the potassium feature of WASP-31b at high-resolution
Neale P. Gibson, Ernst J. W. de Mooij, Thomas M. Evans +4
The analysis and interpretation of exoplanet spectra from time-series observations remains a significant challenge to our current understanding of exoplanet atmospheres, due to the…
Exonephology: Transmission spectra from a 3D simulated cloudy atmosphere of HD209458b
S. Lines, J. Manners, N. J. Mayne +8
We present high resolution transmission spectra, calculated directly from a 3D radiative-hydrodynamics simulation that includes kinetic cloud formation, for HD209458b. We find that…
An absolute sodium abundance for a cloud-free 'hot Saturn' exoplanet
Nikolay Nikolov, David K. Sing, Jonathan J. Fortney +20
Broad absorption signatures from alkali metals, such as the sodium (Na I) and potassium (K I) resonance doublets, have long been predicted in the optical atmospheric spectra of clo…
Helium in the eroding atmosphere of an exoplanet
J. J. Spake, D. K. Sing, T. M. Evans +20
Helium is the second-most abundant element in the Universe after hydrogen and is one of the main constituents of gas-giant planets in our Solar System. Early theoretical models pre…
A Framework for Prioritizing the TESS Planetary Candidates Most Amenable to Atmospheric Characterization
Eliza M. -R. Kempton, Jacob L. Bean, Dana R. Louie +40
A key legacy of the recently launched TESS mission will be to provide the astronomical community with many of the best transiting exoplanet targets for atmospheric characterization…
Observational Techniques With Transiting Exoplanetary Atmospheres
David K. Sing
Transiting exoplanets provide detailed access to their atmospheres, as the planet's signal can be effectively separated from that of its host star. For transiting exoplanets three…
The Transiting Exoplanet Community Early Release Science Program for JWST
Jacob L. Bean, Kevin B. Stevenson, Natalie M. Batalha +99
The James Webb Space Telescope (JWST) presents the opportunity to transform our understanding of planets and the origins of life by revealing the atmospheric compositions, structur…
