Exploring the substellar temperature regime down to ~550K
Ben Burningham, D. J. Pinfield, S. K. Leggett +15
We report the discovery of three very late T dwarfs in the UKIRT Infrared Deep Sky Survey (UKIDSS) Third Data Release: ULAS J101721.40+011817.9 (ULAS1017), ULAS J123828.51+095351.3…
Structural and compositional properties of brown dwarf disks: the case of 2MASS J04442713+2512164
H. Bouy, N. Huelamo, C. Pinte +15
In order to improve our understanding of substellar formation, we have performed a compositional and structural study of a brown dwarf disk. We present the result of photometric, s…
Are isolated planetary-mass objects really isolated? A brown dwarf-exoplanet system candidate in the sigma Orionis cluster
J. A. Caballero, E. L. Martin, P. D. Dobbie +1
The recent detection by direct imaging of three giant planets at wide separation (50-250 AU) from their primaries has raised the question about the ``true isolation'' of planetary-…
Spectroscopic rotational velocities of brown dwarfs
M. R. Zapatero Osorio, E. L. Martin, H. Bouy +3
We have obtained projected rotation velocities (vsini) of a sample of 19 ultracool dwarfs with spectral types in the interval M6.5-T8 using high-resolution, near-infrared spectra o…
Multiplicity of very low-mass objects in the Upper Scorpius OB association: a possible wide binary population
H. Bouy, E. L. Martin, W. Brandner +5
We report the initial results of a VLT/NACO high spatial resolution imaging survey for multiple systems among 58 M-type members of the nearby Upper Scorpius OB association. Nine pa…
Dynamical Masses of the Binary Brown Dwarf GJ 569Bab
M. R. Zapatero Osorio, B. L. Lane, Ya. Pavlenko +3
We have obtained new images and high-resolution (R ~ 22400) near-infrared (1.2400-1.2575 micron) spectra of each component of the brown dwarf binary GJ 569Bab using the Adaptive Op…
