CARMENES input catalogue of M dwarfs IX. Multiplicity from close spectroscopic binaries to ultra-wide systems
C. Cifuentes, J. A. Caballero, J. González-Payo +12
Multiplicity studies greatly benefit from focusing on M dwarfs because they are often paired in a variety of configurations with both stellar and substellar objects, including exop…
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…
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…
The CARMENES search for exoplanets around M dwarfs. Behaviour of the Paschen lines during flares and quiescence
B. Fuhrmeister, S. Czesla, J. H. M. M. Schmitt +17
The hydrogen Paschen lines are known activity indicators, but studies of them in M~dwarfs during quiescence are as rare as their reports in flare studies. This situation is mostly…
CARMENES input catalog of M dwarfs VI. A time-resolved Ca II H&K catalog from archival data
V. Perdelwitz, M. Mittag, L. Tal-Or +15
Radial-velocity (RV) jitter caused by stellar magnetic activity is an important factor in state-of-the-art exoplanet discovery surveys such as CARMENES. Stellar rotation, along wit…
CARMENES input catalogue of M dwarfs V. Luminosities, colours, and spectral energy distributions
C. Cifuentes, J. A. Caballero, M. Cortes-Contreras +15
The relevance of M dwarfs in the search for potentially habitable Earth-sized planets has grown significantly in the last years. In our on-going effort to comprehensively and accur…
