Wind of Change: retrieving exoplanet atmospheric winds from high-resolution spectroscopy
J. V. Seidel, D. Ehrenreich, L. Pino +5
Context. The atmosphere of exoplanets has been studied extensively in recent years, using numerical models to retrieve chemical composition, dynamical circulation or temperature fr…
Transmission Spectroscopy of WASP-79b from 0.6 to 5.0 m
Kristin S. Sotzen, Kevin B. Stevenson, David K. Sing +18
As part of the PanCET program, we have conducted a spectroscopic study of WASP-79b, an inflated hot Jupiter orbiting an F-type star in Eridanus with a period of 3.66 days. Building…
Revised mass-radius relationships for water-rich rocky planets more irradiated than the runaway greenhouse limit
Martin Turbet, Emeline Bolmont, David Ehrenreich +5
Mass-radius relationships for water-rich rocky planets are usually calculated assuming most water is present in condensed (either liquid or solid) form. Planet density estimates ar…
Optical phase curve of the ultra-hot Jupiter WASP-121b
V. Bourrier, D. Kitzmann, T. Kuntzer +28
We present the analysis of TESS optical photometry of WASP-121b, which reveal the phase curve of this transiting ultra-hot Jupiter. Its hotspot is located at the substellar point,…
The detection and characterisation of 54 massive companions with the SOPHIE spectrograph -- 7 new brown dwarfs and constraints on the BD desert
F. Kiefer, G. Hébrard, J. Sahlmann +35
Brown-dwarfs are substellar objects with masses intermediate between planets and stars within about 13-80Mjup. While isolated BDs are most likely produced by gravitational collapse…
The Hubble PanCET program: An extensive search for metallic ions in the exosphere of GJ 436 b
L. A. dos Santos, D. Ehrenreich, V. Bourrier +15
(Abridged) The quiet M2.5 star GJ 436 hosts a warm Neptune that displays an extended atmosphere that dwarfs its own host star. Predictions of atmospheric escape in such planets sta…
