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…
Understanding stellar activity-induced radial velocity jitter using simultaneous K2 photometry and HARPS RV measurements
M. Oshagh, N. C. Santos, P. Figueira +15
One of the best ways to improve our understanding of the stellar activity-induced signal in radial velocity (RV) measurements is through simultaneous high-precision photometric and…
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…
A cautionary tale: limitations of a brightness-based spectroscopic approach to chromatic exoplanet radii
H. M. Cegla, C. Lovis, V. Bourrier +2
Determining wavelength-dependent exoplanet radii measurements is an excellent way to probe the composition of exoplanet atmospheres. In light of this, Borsa et al. (2016) sought to…
