GTC Osiris spectroscopic identification of a faint L subdwarf in the UKIRT Infrared Deep Sky Survey
N. Lodieu, M. R. Zapatero Osorio, E. L. Martin +2
We present the discovery of an L subdwarf in 234 square degrees common to the UK Infrared Telescope (UKIRT) Infrared Deep Sky Survey Large Area Survey Data Release 2 and the Sloan…
CARMENES: Calar Alto high-Resolution search for M dwarfs with Exo-earths with a Near-infrared Echelle Spectrograph
A. Quirrenbach, P. J. Amado, H. Mandel +55
CARMENES, Calar Alto high-Resolution search for M dwarfs with Exo-earths with a Near-infrared Echelle Spectrograph, is a study for a next-generation instrument for the 3.5m Calar A…
Optical linear polarization in ultra cool dwarfs: A tool to probe dust in the ultra cool dwarf atmospheres
R. Tata, E. L. Martin, S. Sengupta +3
Aims.Recent studies have detected linear polarization in L dwarfs in the optical I band. Theoretical models have been developed to explain this polarization. These models predict h…
Infrared radial velocities of vB 10
M. R. Zapatero Osorio, E. L. Martin, C. del Burgo +2
We present radial velocities of the M8V-type, very low-mass star vB 10 that have been obtained at four different epochs of observations between 2001 and 2008. We use high-resolutio…
A census of very-low-mass stars and brown dwarfs in the sigma Orionis cluster
N. Lodieu, M. R. Zapatero Osorio, R. Rebolo +2
(ABRIDGED) We have analysed the near-infrared photometric data from the Fourth Data Release (DR4) of the UKIRT Infrared Deep Sky Suvey (UKIDSS) Galactic Clusters Survey (GCS) to de…
Physical parameters of T dwarfs derived from high-resolution near-infrared spectra
C. del Burgo, E. L. Martin, M. R. Zapatero Osorio +1
We determine the effective temperature, surface gravity and projected rotational velocity of nine T dwarfs from the comparison of high-resolution near-infrared spectra and syntheti…
Lucky Imaging of M subdwarfs
N. Lodieu, M. R. Zapatero Osorio, E. L. Martin
The knowledge of the binary properties of metal-poor and solar-metallicity stars can shed light on the potential differences between the formation processes responsible for both ty…
