Curves of growth for transiting exocomets: Application to Fe II lines in the Beta Pictoris system
T. Vrignaud, A. Lecavelier des Etangs, F. Kiefer +4
This study introduces the exocomet curve of growth, a new method to analyse the variable absorptions observed in Pictoris spectrum and link them to the physical properties of t…
Exocomets size distribution in the Pictoris planetary system
A. Lecavelier des Etangs, L. Cros, G. Hébrard +8
The star Pictoris harbors a young planetary system, which is characterized by the presence of a gaseous and dusty debris disk, at least two massive planets and many minor bodie…
HST PanCET program: Non-detection of atmospheric escape in the warm Saturn-sized planet WASP-29 b
L. A. dos Santos, V. Bourrier, D. Ehrenreich +10
(Abridged) Short-period gas giant exoplanets are susceptible to intense atmospheric escape due to their large scale heights and strong high-energy irradiation. This process is thou…
Determining the true mass of radial-velocity exoplanets with Gaia: 9 planet candidates in the brown-dwarf/stellar regime and 27 confirmed planets
Flavien Kiefer, Guillaume Hébrard, Alain Lecavelier +3
Mass is one of the most important parameters for determining the true nature of an astronomical object. Yet, many published exoplanets lack a measurement of their true mass, in par…
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…
Detection of Nitrogen gas in the Pictoris circumstellar disk
P. A. Wilson, R. Kerr, A. Lecavelier des Etangs +4
The debris disk surrounding Pictoris has a gas composition rich in carbon and oxygen, relative to solar abundances. Two possible scenarios have been proposed to explain this en…
