CARMENES input catalogue of M dwarfs IV. New rotation periods from photometric time series
E. Diez Alonso, J. A. Caballero, D. Montes +21
Aims. The main goal of this work is to measure rotation periods of the M-type dwarf stars being observed by the CARMENES exoplanet survey to help distinguish radial-velocity signal…

Two planetary systems with transiting Earth-size and super-Earth planets orbiting late-type dwarf stars
E. Diez Alonso, J. I. Gonzalez Hernandez, S. L. Suarez Gomez +9
We present two new planetary systems found around cool dwarf stars with data from the K2 mission. The first system was found in K2-239 (EPIC 248545986), char- acterized in this wor…

CARMENES input catalogue of M dwarfs: III. Rotation and activity from high-resolution spectroscopic observations
S. V. Jeffers, P. Schoefer, A. Lamert +18
CARMENES is a spectrograph for radial velocity surveys of M dwarfs with the aim of detecting Earth-mass planets orbiting in the habitable zones of their host stars. To ensure an op…
