Two close binaries across the hydrogen-burning limit in the Praesepe open cluster
N. Lodieu, C. del Burgo, E. Manjavacas +7
We present Keck I/OSIRIS and Keck II/NIRC2 adaptive optics imaging of two member candidates of the Praesepe stellar cluster (d=186.180.11 pc; 590-790 Myr), UGC J08451066+21481…
Spectral library of age-benchmark low-mass stars and brown dwarfs
E. Manjavacas, N. Lodieu, V. J. S. Béjar +3
In the past years, some extremely red brown dwarfs were found. They were believed to have low surface gravity, but many of their spectral characteristics were similar to those of h…
A test field for Gaia. Radial velocity catalogue of stars in the South Ecliptic Pole
Y. Frémat, M. Altmann, E. Pancino +25
Gaia is a space mission currently measuring the five astrometric parameters as well as spectrophotometry of at least 1 billion stars to G = 20.7 mag with unprecedented precision. T…
Spectroscopic follow-up of L- and T-type proper-motion member candidates in the Pleiades
M. R. Zapatero Osorio, V. J. S. Béjar, E. L. Martín +9
(Abridged) We report on the near-infrared low-resolution spectroscopy and red optical (Z-band) photometry of seven proper-motion, very low-mass substellar member candidates of the…
Spectroscopy of Hyades L dwarf candidates
N. Lodieu, S. Boudreault, V. J. S. Bejar
We present the results of photometric, astrometric, and spectroscopic follow-up of L dwarf candidates identified in the Hyades cluster by Hogan et al. (2008). We obtained low-resol…
Search for free-floating planetary-mass objects in the Pleiades
M. R. Zapatero Osorio, M. C. Gálvez Ortiz, G. Bihain +8
(Abridged) We aim at identifying the least massive population of the solar metallicity, young (120 Myr), nearby (133.5 pc) Pleiades star cluster with the ultimate goal of understan…
