HELIOS-Retrieval: An Open-source, Nested Sampling Atmospheric Retrieval Code, Application to the HR 8799 Exoplanets and Inferred Constraints for Planet Formation
Baptiste Lavie, João M. Mendonça, Christoph Mordasini +7
We present an open-source retrieval code named HELIOS-Retrieval (hereafter HELIOS-R), designed to obtain chemical abundances and temperature-pressure profiles from inverting the me…
No hydrogen exosphere detected around the super-Earth HD97658 b
Vincent Bourrier, David Ehrenreich, George King +5
The exoplanet HD97658b provides a rare opportunity to probe the atmospheric composition and evolution of moderately irradiated super-Earths. It transits a bright K star at a modera…
Atmospheric characterization of Proxima b by coupling the Sphere high-contrast imager to the Espresso spectrograph
C. Lovis, I. Snellen, D. Mouillet +17
Context. The temperate Earth-mass planet Proxima b is the closest exoplanet to Earth and represents what may be our best ever opportunity to search for life outside the Solar Syste…
Sparse aperture masking at the VLT II. Detection limits for the eight debris disks stars Pic, AU Mic, 49 Cet, Tel, Fomalhaut, g Lup, HD181327 and HR8799
L. Gauchet, S. Lacour, A. -M. Lagrange +4
Context. The formation of planetary systems is a common, yet complex mechanism. Numerous stars have been identified to possess a debris disk, a proto-planetary disk or a planetary…
An evaporating planet in the wind: stellar wind interactions with the radiatively braked exosphere of GJ436 b
Vincent Bourrier, Alain Lecavelier des Etangs, David Ehrenreich +2
The warm Neptune GJ436b was observed with HST/STIS at three different epochs in the stellar Ly-alpha line, showing deep, repeated transits caused by a giant exosphere of neutral hy…
Strong XUV irradiation of the Earth-sized exoplanets orbiting the ultracool dwarf TRAPPIST-1
Peter J. Wheatley, Tom Louden, Vincent Bourrier +2
We present an XMM-Newton X-ray observation of TRAPPIST-1, which is an ultracool dwarf star recently discovered to host three transiting and temperate Earth-sized planets. We find t…
