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…
The SOPHIE search for northern extrasolar planets. XVI. HD 158259: A compact planetary system in a near-3:2 mean motion resonance chain
N. C. Hara, F. Bouchy, M. Stalport +32
Since 2011, the SOPHIE spectrograph has been used to search for Neptunes and super-Earths in the Northern Hemisphere. As part of this observational program, 290 radial velocity mea…
WASP-52b. The effect of starspot correction on atmospheric retrievals
Giovanni Bruno, Nikole K. Lewis, Munazza K. Alam +13
We perform atmospheric retrievals on the full optical to infrared () transmission spectrum of the inflated hot Jupiter WASP-52b by combining HST/STIS, WFC3 IR…
Multi-season optical modulation phased with the orbit of the super-Earth 55 Cnc e
S. Sulis, D. Dragomir, M. Lendl +13
Context. 55 Cnc e is a transiting super-Earth orbiting a solar-like star with an orbital period of 17.7 hours. In 2011, using the MOST space telescope, a quasi-sinusoidal modulatio…
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…
