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 Gaia Ultracool Dwarf Sample -- IV. GTC/OSIRIS optical spectra of Gaia late-M and L dwarfs
W. J. Cooper, H. R. A. Jones, R. L. Smart +20
As part of our comprehensive, ongoing characterisation of the low-mass end of the main sequence in the Solar neighbourhood, we used the OSIRIS instrument at the 10.4 m Gran Telesco…
The CARMENES search for exoplanets around M dwarfs: Magnesium and silicon abundances of K7-M5.5 stars
H. M. Tabernero, Y. Shan, J. A. Caballero +13
We present the abundances of magnesium (Mg) and silicon (Si) for 314 dwarf stars with spectral types in the interval K7.0-M5.5 (Teff range ~4200-3050 K) observed with the CARMENES…
Using autoencoders and deep transfer learning to determine the stellar parameters of 286 CARMENES M dwarfs
P. Mas-Buitrago, A. González-Marcos, E. Solano +9
Deep learning (DL) techniques are a promising approach among the set of methods used in the ever-challenging determination of stellar parameters in M dwarfs. In this context, trans…
CARMENES input catalog of M dwarfs: VII. New rotation periods for the survey stars and their correlations with stellar activity
Yutong Shan, Daniel Revilla, Sebastian L. Skrzypinski +40
Abridged: We measured photometric and spectroscopic for a large sample of nearby bright M dwarfs with spectral types from M0 to M9, as part of our continual effort to…
