Orbital misalignment of the Neptune-mass exoplanet GJ 436b with the spin of its cool star
Vincent Bourrier, Christophe Lovis, Hervé Beust +12
The angle between the spin of a star and its planets' orbital planes traces the history of the planetary system. Exoplanets orbiting close to cool stars are expected to be on circu…
Search for water vapor in the high-resolution transmission spectrum of HD189733b in the visible
R. Allart, C. Lovis, L. Pino +3
Ground-based telescopes equipped with state-of-the-art spectrographs are able to obtain high-resolution transmission and emission spectra of exoplanets that probe the structure and…
Strong HI Lyman- variations from the 11 Gyr-old host star Kepler-444: a planetary origin ?
V. Bourrier, D. Ehrenreich, R. Allart +8
Kepler-444 provides a unique opportunity to probe the atmospheric composition and evolution of a compact system of exoplanets smaller than the Earth. Five planets transit this brig…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) I. Detection of hot neutral sodium at high altitudes on WASP-49b
A. Wyttenbach, C. Lovis, D. Ehrenreich +13
High-resolution optical spectroscopy during the transit of HD 189733b, a prototypical hot Jupiter, allowed the resolution of the Na I D sodium lines in the planet, giving access to…
