USco1621 B and USco1556 B: Two wide companions at the deuterium-burning mass limit in Upper Scorpius
Patricia Chinchilla, Víctor J. S. Béjar, Nicolas Lodieu +6
(Abridged) Our aim is to identify analogues of gas giant planets, as companions at wide separations of very young stars. To identify these objects, we cross correlated the Visible…
Cloud Atlas: Weak color modulations due to rotation in the planetary-mass companion GU Psc b and 11 other brown dwarfs
Ben W. P. Lew, Dániel Apai, Yifan Zhou +10
Among the greatest challenges in understanding ultra-cool brown dwarf and exoplanet atmospheres is the evolution of cloud structure as a function of temperature and gravity. In thi…
Spectral library of age-benchmark low-mass stars and brown dwarfs
E. Manjavacas, N. Lodieu, V. J. S. Béjar +3
In the past years, some extremely red brown dwarfs were found. They were believed to have low surface gravity, but many of their spectral characteristics were similar to those of h…
A new take on the low-mass brown dwarf companions on wide-orbits in Upper-Scorpius
Simon Petrus, Mickaël Bonnefoy, Gaël Chauvin +10
The Upper-Scorpius association (5-11 Myr) contains a unique population of low-mass (M<30 MJup) brown-dwarfs. The detailed relative characterization of their physical properties (ma…
Cloud Atlas: Variability in and out of the Water Band in the Planetary-mass HD 203030B Points to Cloud Sedimentation in Low-gravity L Dwarfs
Paulo A. Miles-Páez, Stanimir Metchev, Dániel Apai +11
We use the Wide Field Camera 3 on the {\sl Hubble Space Telescope} to spectrophotometrically monitor the young L7.5 companion HD~203030B. Our time series reveal photometric variabi…
Cloud Atlas: Rotational Spectral Modulations and potential Sulfide Clouds in the Planetary-mass, Late T-type Companion Ross 458C
Elena Manjavacas, Daniel Apai, Ben W. P. Lew +11
Measurements of photometric variability at different wavelengths provide insights into the vertical cloud structure of brown dwarfs and planetary-mass objects. In seven Hubble Spac…
