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 solar gravitational redshift from HARPS-LFC Moon spectra. A test of the General Theory of Relativity
J. I. González Hernández, R. Rebolo, L. Pasquini +15
The General Theory of Relativity predicts the redshift of spectral lines in the solar photosphere, as a consequence of the gravitational potential of the Sun. This effect can be me…
A detailed non-LTE analysis of LB-1: Revised parameters and surface abundances
S. Simón-Díaz, J. Maíz Apellániz, D. J. Lennon +8
LB-1 has recently been proposed to be a binary system at 4 kpc consisting of a B star of 8 Msol and a massive stellar black hole of 70 Msol. This finding challenges our current the…
HADES RV Programme with HARPS-N at TNG. X. The non-saturated regime of the stellar activity-rotation relationship for M-Dwarfs
E. González-Álvarez, G. Micela, J. Maldonado +22
Aims. We aim to extend the relationship between X-ray luminosity (Lx) and rotation period (Prot) found for main-sequence FGK stars and test whether it also holds for early-M dwarfs…
High-resolution spectroscopy of Boyajian's star during optical dimming events
M. J. Martínez González, C. González-Fernández, A. Asensio Ramos +13
Boyajian's star is an apparently normal main sequence F-type star with a very unusual light curve. The dipping activity of the star, discovered during the Kepler mission, presents…
HADES RV Programme with HARPS-N at TNG. VII. Rotation and activity of M-Dwarfs from time-series high-resolution spectroscopy of chromospheric indicators
A. Suárez Mascareño, R. Rebolo, J. I. González Hernández +28
We aim to investigate the presence of signatures of magnetic cycles and rotation on a sample of 71 early M-dwarfs from the HADES RV programme using high-resolution time-series spec…
