CARMENES input catalogue of M dwarfs V. Luminosities, colours, and spectral energy distributions

C. Cifuentes, J. A. Caballero, M. Cortes-Contreras +15

The relevance of M dwarfs in the search for potentially habitable Earth-sized planets has grown significantly in the last years. In our on-going effort to comprehensively and accur…

Polarisation of very-low-mass stars and brown dwarfs

B. Goldman, J. Pitann, M. R. Zapatero Osorio +4

Ultra-cool dwarfs of the L spectral type (Teff=1400-2200K) are known to have dusty atmospheres. Asymmetries of the dwarf surface may arise from rotationally-induced flattening and…

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 ~…

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…

A multiwavelength radial velocity search for planets around the brown dwarf LP 944-20

E. L. Martin, E. Guenther, M. R. Zapatero Osorio +2

The nearby brown dwarf LP 944-20 has been monitored for radial velocity variability at optical and near-infrared wavelengths using the VLT/UVES and the Keck/NIRSPEC spectrographs,…

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…
