Discovery of a young planetary mass companion to the nearby M dwarf VHS J125601.92-125723.9
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 previously unrecognizedExpand

CARMENES input catalogue of M dwarfs - II. High-resolution imaging with FastCam
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 the CARMENESExpand

On the HU Aquarii planetary system hypothesis
In this paper, 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) deviations between theExpand

Binary frequency of planet-host stars at wide separations: A new brown dwarf companion to a planet-host star
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 the Southern skyExpand

A low-mass triple system with a wide L/T transition brown dwarf component: NLTT 51469AB/SDSS 2131−0119
We demonstrate that the previously identified L/T transition brown dwarf SDSS J213154.43-011939.3 (SDSS 2131-0119) is a widely separated (82.3'', $\sim$3830 au) common proper motion companion to theExpand

USco1621 B and USco1556 B: Two wide companions at the deuterium-burning mass limit in Upper Scorpius
(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 and Infrared SurveyExpand

Constraints on the substellar companions in wide orbits around the Barnard's Star from CanariCam mid-infrared imaging
We have performed mid-infrared imaging of Barnard's Star, one of the nearest stars to the Sun, using CanariCam on the 10.4 m Gran Telescopio Canarias. We aim to investigate an area within 1-10 arcsecExpand

A deep WISE search for very late type objects and the discovery of two halo/thick-disc T dwarfs: WISE 0013+0634 and WISE 0833+0052
A method is defined for identifying late T and Y dwarfs in WISE down to low values of signal-to-noise. This requires a WISE detection only in the W2-band and uses the statistical properties of theExpand

Benchmark brown dwarf companions as exoplanets analogues
Directly imaged substellar companions around stars are key objects for better understanding the formation and evolution of brown dwarfs and massive planets, as we can infer physical properties likeExpand
