Confirming the least massive members of the Pleiades star cluster
M. R. Zapatero Osorio, V. J. S. Béjar, N. Lodieu +1
We present optical photometry (i- and Z-band) and low-resolution spectroscopy (640-1015 nm) of very faint candidate members (J = 20.2-21.2 mag) of the Pleiades star cluster (120 My…
Radio emission in ultracool dwarfs: the nearby substellar triple system VHS 12561257
J. C. Guirado, R. Azulay, B. Gauza +4
With the purpose to investigate the radio emission of new ultracool objects, we carried out a targeted search in the recently discovered system VHS J125601.92125723.9 (hereafter…
The CARMENES search for exoplanets around M dwarfs: High-resolution optical and near-infrared spectroscopy of 324 survey stars
A. Reiners, M. Zechmeister, J. A. Caballero +170
The CARMENES radial velocity (RV) survey is observing 324 M dwarfs to search for any orbiting planets. In this paper, we present the survey sample by publishing one CARMENES spectr…
The CARMENES search for exoplanets around M dwarfs. First visual-channel radial-velocity measurements and orbital parameter updates of seven M-dwarf planetary systems
T. Trifonov, M. Kürster, M. Zechmeister +166
Context: The main goal of the CARMENES survey is to find Earth-mass planets around nearby M-dwarf stars. Seven M-dwarfs included in the CARMENES sample had been observed before wit…
Testing the existence of optical linear polarization in young brown dwarfs
E. Manjavacas, P. A. Miles-Páez, M. R. Zapatero-Osorio +5
Linear polarization can be used as a probe of the existence of atmospheric condensates in ultracool dwarfs. Models predict that the observed linear polarization increases withthe d…
