The CARMENES search for exoplanets around M dwarfs: Spectroscopic orbits of nine M-dwarf multiple systems, including two triples, two brown dwarf candidates, and one close M-dwarf-white dwarf binary

D. Baroch, J. C. Morales, I. Ribas +33

M dwarfs are ideal targets for the search of Earth-size planets in the habitable zone using the radial velocity method, attracting the attention of many ongoing surveys. As a by-pr…

HADES RV Programme with HARPS-N at TNG XII. The abundance signature of M dwarf stars with planets

J. Maldonado, G. Micela, M. Baratella +27

Most of our current knowledge on planet formation is still based on the analysis of main-sequence, solar-type stars. Conversely, detailed chemical studies of large samples of M-dwa…

The CARMENES search for exoplanets around M dwarfs: Convective shift and starspot constraints from chromatic radial velocities

D. Baroch, J. C. Morales, I. Ribas +26

Context. Variability caused by stellar activity represents a challenge to the discovery and characterization of terrestrial exoplanets and complicates the interpretation of atmosph…

Stellar activity analysis of Barnard's Star: Very slow rotation and evidence for long-term activity cycle

B. Toledo-Padrón, J. I. González Hernández, C. Rodríguez-López +58

The search for Earth-like planets around late-type stars using ultra-stable spectrographs requires a very precise characterization of the stellar activity and the magnetic cycle of…

The CARMENES search for exoplanets around M dwarfs: Nine new double-line spectroscopic binary stars

D. Baroch, J. C. Morales, I. Ribas +27

Context. The CARMENES spectrograph is surveying ~300 M dwarf stars in search for exoplanets. Among the target stars, spectroscopic binary systems have been discovered, which can be…

GJ1214: Rotation period, starspots, and uncertainty on the optical slope of the transmission spectrum

M. Mallonn, E. Herrero, I. G. Juvan +6

Brightness inhomogeneities in the stellar photosphere (dark spots or bright regions) affect the measurements of the planetary transmission spectrum. To investigate the star spots o…
