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…
MIRACLES: atmospheric characterization of directly imaged planets and substellar companions at 4-5 m. I. Photometric analysis of Pic b, HIP 65426 b, PZ Tel B and HD 206893 B
Tomas Stolker, Sascha P. Quanz, Kamen O. Todorov +6
Directly imaged planets and substellar companions are key targets for the characterization of self-luminous atmospheres. Their photometric appearance at 4-5 m is sensitive to th…
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 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…
A spectral survey of an ultra-hot Jupiter: Detection of metals in the transmission spectrum of KELT-9 b
H. J. Hoeijmakers, D. Ehrenreich, D. Kitzmann +16
Context: KELT-9 b exemplifies a newly emerging class of short-period gaseous exoplanets that tend to orbit hot, early type stars - termed ultra-hot Jupiters. The severe stellar irr…
The CORALIE survey for southern extrasolar planets XVIII. Three new massive planets and two low mass brown dwarfs at separation larger than 5 AU
E. L. Rickman, D. Ségransan, M. Marmier +36
Context. Since 1998, a planet-search around main sequence stars within 50~pc in the southern hemisphere has been carried out with the CORALIE spectrograph at La Silla Observatory.…
