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…
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 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…
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…
