CARMENES input catalogue of M dwarfs I. Low-resolution spectroscopy with CAFOS

Description: Context. CARMENES is a stabilised, high-resolution, double-channel spectrograph at the 3.5m Calar Alto telescope. It is optimally designed for radial-velocity surveys of M dwarfs with potentially habitable Earth-mass planets. Aims. We prepare a list of the brightest, single M dwarfs in each spectral...

Efficient scheduling of astronomical observations: Application to the CARMENES radial-velocity survey

Description: Context. Targeted spectroscopic exoplanet surveys face the challenge of maximizing their planet detection rates by means of careful planning. For a large planet survey, the number of possible observation combinations, i.e., the sequence of observations night after night, both in total time and amoun...

CARMENES input catalogue of M dwarfs: II. High-resolution imaging with FastCam

Description: Aims. We search for low-mass companions of M dwarfs and characterize their multiplicity fraction with the purpose of helping in the selection of the most appropriate targets for the CARMENES exoplanet survey. Methods. We obtained high-resolution images in the I band with the lucky imaging instrument...

The CARMENES search for exoplanets around M dwarfs: different roads to radii and masses of the target stars

Description: Aims. We determine the radii and masses of 293 nearby, bright M dwarfs of the CARMENES survey. This is the first time that such a large and homogeneous high-resolution (R > 80, 000) spectroscopic survey has been used to derive these fundamental stellar parameters. Methods. We derived the radii using...

The CALIFA survey across the Hubble sequence: Spatially resolved stellar population properties in galaxies

Description: © ESO, 2015. Various different physical processes contribute to the star formation and stellar mass assembly histories of galaxies. One important approach to understanding the significance of these different processes on galaxy evolution is the study of the stellar population content of today's gala...
