Stellar parameters for TRAPPIST-1
Valerie Van Grootel, Catarina S. Fernandes, Michaël Gillon +10
TRAPPIST-1 is an ultracool dwarf star transited by seven Earth-sized planets, for which thorough characterization of atmospheric properties, surface conditions encompassing habitab…
Refraction in exoplanet atmospheres: Photometric signatures, implications for transmission spectroscopy, and search in Kepler data
Dennis Alp, Brice-Olivier Demory
Refraction deflects photons that pass through atmospheres, which affects transit light curves. Refraction thus provides an avenue to probe physical properties of exoplanet atmosphe…
High-precision multi-wavelength eclipse photometry of the ultra-hot gas giant exoplanet WASP-103 b
L. Delrez, N. Madhusudhan, M. Lendl +14
We present sixteen occultation and three transit light curves for the ultra-short period hot Jupiter WASP-103 b, in addition to five new radial velocity measurements. We combine th…
Retrieval Analysis of the Emission Spectrum of WASP-12b: Sensitivity of Outcomes to Prior Assumptions and Implications for Formation History
Maria Oreshenko, Baptiste Lavie, Simon L. Grimm +9
We analyze the emission spectrum of the hot Jupiter WASP-12b using our HELIOS-R retrieval code and HELIOS-K opacity calculator. When interpreting Hubble and Spitzer data, the retri…
Temporal evolution of the high-energy irradiation and water content of TRAPPIST-1 exoplanets
V. Bourrier, J. de Wit, E. Bolmont +13
The ultracool dwarf star TRAPPIST-1 hosts seven Earth-size transiting planets, some of which could harbour liquid water on their surfaces. UV observations are essential to measure…
Two massive rocky planets transiting a K-dwarf 6.5 parsecs away
Michael Gillon, Brice-Olivier Demory, Valerie Van Grootel +14
HD 219134 is a K-dwarf star at a distance of 6.5 parsecs around which several low-mass planets were recently discovered. The Spitzer space telescope detected a transit of the inner…
