Spectroscopic characterisation of CARMENES target candidates from FEROS, CAFE and HRS high-resolution spectra
V. M. Passegger, A. Reiners, S. V. Jeffers +9
CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectrographs) started a new planet survey on M-dwarfs in January thi…
The spectral type of CHS7797 - an intriguing very low mass periodic variable in the Orion Nebula Cluster
M. V. Rodriguez-Ledesma, R. Mundt, O. Pintado +3
We present the spectroscopic characterization of the unusual high-amplitude very low mass pre-main-sequence periodic variable CHS7797. This study is based on optical medium-resolut…
The substellar population of Sigma Orionis: A deep wide survey
V. J. S. Béjar, M. R. Zapatero Osorio, R. Rebolo +5
We present a deep I,Z photometric survey covering a total area of 1.12 deg^{2} of the Sigma Orionis cluster (Icompl=22 and Zcompl=21.5mag). From I, I-Z color-magnitude diagrams we…
