Discovery of a wide companion near the deuterium burning mass limit in the Upper Scorpius association
V. J. S. Bejar, M. R. Zapatero Osorio, A. Perez-Garrido +5
We present the discovery of a companion near the deuterium burning mass limit located at a very wide distance, at an angular separation of 4.6+/-0.1 arcsec (projected distance of ~…
Simultaneous Multi-Wavelength Observations of Magnetic Activity in Ultracool Dwarfs. II. Mixed Trends in VB10 and LSR1835+32 and the Possible Role of Rotation
E. Berger, G. Basri, J. E. Gizis +8
[Abridged] As part of our on-going investigation of magnetic activity in ultracool dwarfs we present simultaneous radio, X-ray, UV, and optical observations of LSR1835+32 (M8.5), a…
Discovery of new nearby L and late-M dwarfs at low Galactic latitude from the DENIS database
N. Phan-Bao, M. S. Bessell, E. L. Martin +9
We report new nearby L and late-M dwarfs (d_phot <= 30 pc) discovered in our search for nearby ultracool dwarfs (I-J >= 3.0, later than M8.0) at low Galactic latitude (|b| < 15 deg…
Lithium in LP 944-20
Ya. V. Pavlenko, H. R. A. Jones, E. L. Martin +3
We present a new estimate of the lithium abundance in the atmosphere of the brown dwarf LP 944-20. Our analysis is based on a self-consistent analysis of low, intermediate and high…
Space Velocities of L- and T-type Dwarfs
M. R. Zapatero Osorio, E. L. Martin, V. J. S. Bejar +3
(Abridged) We have obtained radial velocities of a sample of 18 ultracool dwarfs (M6.5-T8) using high-resolution, near-infrared spectra obtained with NIRSPEC and the Keck II telesc…
