An extensive spectroscopic time series of three Wolf-Rayet stars -- II. A search for wind asymmetries in the dust-forming WC7 binary WR137
N. St-Louis, C. Piaulet, N. D. Richardson +39
We present the results of a four-month, spectroscopic campaign of the Wolf-Rayet dust-making binary, WR137. We detect only small-amplitude, random variability in the CIII5696 emiss…
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…
CARMENES input catalogue of M dwarfs II. High-resolution imaging with FastCam
M. Cortes-Contreras, V. J. S. Bejar, J. A. Caballero +12
Aims: We search for low-mass companions of M dwarfs and characterize their multiplicity fraction with the purpose of helping in the selection of the most appropriate targets for th…
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…
