Chemical abundances of late-type pre-main sequence stars in the -Orionis cluster
J. I. González Hernández, J. A. Caballero, R. Rebolo +4
The young -Orionis cluster is an important location for understanding the formation and evolution of stars, brown dwarfs, and planetary-mass objects. Its metallicity, although b…
CLOUDS search for variability in brown dwarf atmospheres
B. Goldman, M. C. Cushing, M. S. Marley +21
Context: L-type ultra-cool dwarfs and brown dwarfs have cloudy atmospheres that could host weather-like phenomena. The detection of photometric or spectral variability would provid…
The substellar mass function in sigma Orionis. II. Optical, near-infrared and IRAC/Spitzer photometry of young cluster brown dwarfs and planetary-mass objects
J. A. Caballero, V. J. S. Béjar, R. Rebolo +8
We investigate the mass function in the substellar domain down to a few Jupiter masses in the young sigma Orionis open cluster (3+/-2 Ma, d = 360^+70_-60 pc). We have performed a d…
A search for substellar members in the Praesepe and sigma Orionis clusters
B. M. Gonzalez-Garcia, M. R. Zapatero Osorio, V. J. S. Bejar +4
(Abridged). We have conducted deep photometric searches for substellar members of the Praesepe (0.5-1 Gyr) and sigma Orionis (3 Myr) star clusters using the Sloan i' and z' filters…
Proper motion Pleiades candidate L-type brown dwarfs
G. Bihain, R. Rebolo, V. J. S. Bejar +3
We present results of an optical and near-infrared (IR) 1.8 deg^2 survey in the Pleiades open cluster to search for substellar objects. From optical I-band images from the CFHT and…
S Ori J053825.4-024241: A Classical T Tauri-like object at the substellar boundary
J. A. Caballero, E. L. Martín, M. R. Zapatero Osorio +4
We present a spectrophotometric analysis of S Ori J053825.4-024241, a candidate member close to the substellar boundary of the young (1-8 Myr), nearby (~360 pc) sigma Orionis star…
