Characterization of Low-mass, Wide-separation Substellar Companions to Stars in Upper Scorpius: Near-infrared Photometry and Spectroscopy
François-René Lachapelle, David Lafrenière, Jonathan Gagné +4
We present new 0.9-2.45 m spectroscopy (), and , , , , photometry, obtained at Gemini North, of three low-mass brown dwarf companions on wi…
Dust cloud lightning in extraterrestrial atmospheres
Christiane Helling, Moira Jardine, Declan Diver +1
Lightning is present in all solar system planets which form clouds in their atmospheres. Cloud formation outside our solar system is possible in objects with much higher temperatur…
Spectroscopy across the brown dwarf/planetary mass boundary - I. Near-infrared JHK spectra
J. Patience, R. R. King, R. J. De Rosa +5
With a uniform VLT SINFONI data set of nine targets, we have developed an empirical grid of J,H,K spectra of the atmospheres of objects estimated to have very low substellar masses…
The influence of non-isotropic scattering of thermal radiation on spectra of brown dwarfs and hot exoplanets
R. J. de Kok, Ch. Helling, D. M. Stam +2
(abridged) We calculate near-infrared thermal emission spectra using a doubling-adding radiative transfer code, which includes scattering by clouds and haze. Initial temperature pr…
Detecting Planets around Very Cool Dwarfs at Near Infrared Wavelengths with the Radial Velocity Technique
Florian Rodler, Carlos del Burgo, Soeren Witte +4
Context. Radial velocity monitoring of very cool dwarfs such as late M- and hot L-dwarfs has become a promising tool to search for rocky planets as well as to follow-up planetary c…
Discovery of a ~23 Mjup Brown Dwarf Orbiting ~700 AU from the Massive Star HIP 78530 in Upper Scorpius
David Lafrenière, Ray Jayawardhana, Markus Janson +3
We present the discovery of a substellar companion on a wide orbit around the ~2.5 Msun star HIP 78530, which is a member of the 5 Myr-old Upper Scorpius association. We have obtai…
