Silicate Precursor Silane detected in Cold Low-Metallicity Brown Dwarf
Jacqueline K. Faherty, Aaron M. Meisner, Ben Burningham +28
Within 20 pc of the Sun there are currently 29 known cold brown dwarfs, sources with measured distances and an estimated effective temperature between that of Jupiter (170K) and ~5…
New constraints on the presence of debris disks around G 196-3 B and VHS J125601.92-125723.9 b
O. V. Zakhozhay, M. R. Zapatero Osorio, V. J. S. Bejar +10
We obtained deep images of G 196-3 B and VHS J1256-1257 b with the NOrthern Extended Millimeter Array (NOEMA) at 1.3 mm. These data were combined with recently published Atacama La…
Strong H emission in the young planetary mass companion 2MASS J0249-0557 c
P. Chinchilla, V. J. S. Béjar, N. Lodieu +2
Aims: Our objective is the optical and near-infrared spectroscopic characterisation of 2MASS J0249-0557 c, a recently discovered young planetary mass companion to the Pictoris…
Maintaining the Ephemeris of 20 CoRoT Planets: Transit Minimum Times and Potential Transit Timing Variations
Hans J. Deeg, Peter Klagyivik, J. D. Armstrong +11
We present 33 transit minimum times of 20 transiting planets discovered by the CoRoT mission, which have been obtained from ground-based observations since the mission's end in 201…
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…
Discovery of a young planetary mass companion to the nearby M dwarf VHS J125601.92-125723.9
Bartosz Gauza, Victor J. S. Béjar, Antonio Pérez-Garrido +5
In a search for common proper motion companions using the VISTA Hemisphere Survey and 2MASS catalogs we have identified a very red (J-Ks=2.47 mag) late-L dwarf companion of a previ…
Binary frequency of planet-host stars at wide separations: A new brown dwarf companion to a planet-host star
N. Lodieu, A. Perez-Garrido, V. J. S. Bejar +5
The aim of the project is to improve our knowledge on the multiplicity of planet-host stars at wide physical separations. We cross-matched approximately 6200 square degree area of…
On the HU Aquarii planetary system hypothesis
Krzysztof Gozdziewski, Ilham Nasiroglu, Aga Slowikowska +11
In this work, we investigate the eclipse timing of the polar binary HU Aquarii that has been observed for almost two decades. Recently, Qian et al. attributed large (O-C) deviation…
