Properties of ultra-cool dwarfs with Gaia. An assessment of the accuracy for the temperature determination
Luis M. Sarro, Angel Berihuete, Cesar Carrion +3
We aimed to assess the accuracy of the Gaia teff and logg estimates as derived with current models and observations. We assessed the validity of several inference techniques for de…
The first planet detected in the WTS: an inflated hot-Jupiter in a 3.35 day orbit around a late F-star
M. Cappetta, R. P. Saglia, J. L. Birkby +36
We report the discovery of WTS-1b, the first extrasolar planet found by the WFCAM Transit Survey, which began observations at the 3.8-m United Kingdom Infrared Telescope. Light cur…
CALIFA, the Calar Alto Legacy Integral Field Area survey. II. First public data release
CALIFA collaboration, B. Husemann, K. Jahnke +74
We present the first public data release of the CALIFA survey. It consists of science-grade optical datacubes for the first 100 of eventually 600 nearby (0.005<z<0.03) galaxies, ob…
HD 172555: detection of 63 microns [OI] emission in a debris disc
P. Riviere-Marichalar, D. Barrado, J. -C. Augereau +14
Context. HD 172555 is a young A7 star belonging to the Beta Pictoris Moving Group that harbours a debris disc. The Spitzer IRS spectrum of the source showed mid-IR features such as…
Spectroscopy of Very Low Mass Stars and Brown Dwarfs in the Lambda Orionis Star Forming Region
A. Bayo, D. Barrado, N. Huélamo +4
Context. Most observational studies so far point towards brown dwarfs sharing a similar formation mechanism as the one accepted for low mass stars. However, larger databases and mo…
Multiplicity in transiting planet host stars. A Lucky Imaging study of Kepler candidates
J. Lillo-Box, D. Barrado, H. Bouy
In the exoplanetary era, the Kepler spacecraft is causing a revolution by discovering thousands of new planet candidates. However, a follow up program is needed in order to reject…
