The CARMENES search for exoplanets around M dwarfs. Cluster analysis of signals from spectral activity indicators to search for shared periods
J. Kemmer, M. Lafarga, B. Fuhrmeister +17
A multitude of spectral activity indicators are routinely computed nowadays from the spectra generated as part of planet-hunting radial velocity surveys. Searching for shared perio…
CARMENES input catalogue of M dwarfs VIII. Kinematics in the solar neighbourhood
M. Cortés-Contreras, J. A. Caballero, D. Montes +15
Aims. Our goals are to characterise the kinematic properties and to identify young and old stars among the M dwarfs of the CARMENES input catalogue. Methods. We compiled the spectr…
The CARMENES search for exoplanets around M dwarfs. Telluric absorption corrected high S/N optical and near-infrared template spectra of 382 M dwarf stars
E. Nagel, S. Czesla, A. Kaminski +22
Light from celestial objects interacts with the molecules of the Earth's atmosphere, resulting in the production of telluric absorption lines in ground-based spectral data. Correct…
The CARMENES search for exoplanets around M dwarfs. Line-by-line sensitivity to activity in M dwarfs
M. Lafarga, I. Ribas, M. Zechmeister +17
Radial velocities (RVs) measured from high-resolution stellar spectra are routinely used to detect and characterise orbiting exoplanet companions. The different lines present in st…
The CARMENES search for exoplanets around M dwarfs. Rotational variation in activity indicators of Ross 318, YZ CMi, TYC 3529-1437-1, and EV Lac
P. Schöfer, S. V. Jeffers, A. Reiners +22
The CARMENES instrument is searching for periodic radial-velocity (RV) variations of M dwarfs, which are induced by orbiting planets. However, there are other potential sources of…
The CARMENES search for exoplanets around M dwarfs. Stellar atmospheric parameters of target stars with SteParSyn
Emilio Marfil, Hugo M. Tabernero, David Montes +24
We determined effective temperatures, surface gravities, and metallicities for a sample of 343 M dwarfs observed with CARMENES, the double-channel, high-resolution spectrograph ins…
