A super-Earth orbiting the nearby M-dwarf GJ 536
A. Suárez Mascareño, J. I. González Hernández, R. Rebolo +13
We report the discovery of a super-Earth orbiting the star GJ 536 based on the analysis of the radial-velocity time series from the HARPS and HARPS-N spectrographs. GJ 536 b is a p…
The HADES RV Programme with HARPS-N@TNG. III. Flux-flux and activity-rotation relationships of early-M dwarfs
J. Maldonado, G. Scandariato, B. Stelzer +23
(Abridged) Understanding stellar activity in M dwarfs is crucial for the physics of stellar atmospheres as well as for ongoing radial velocity exoplanet programmes. Despite the inc…
The HADES RV Programme with HARPS-N@TNG IV. Time resolved analysis of the Ca ii H&K and Hα chromospheric emission of low-activity early-type M dwarfs
G. Scandariato, J. Maldonado L. Affer, K. Biazzo +22
M dwarfs are prime targets for planet search programs, particularly of those focused on the detection and characterization of rocky planets in the habitable zone. Understanding the…
Magnetic Cycles and Rotation Periods of Late Type Stars from photometric time series
A. Suárez Mascareño, R. Rebolo, J. I. González Hernández
We investigate the photometric modulation induced by magnetic activity cycles and study the relationship between rotation period and activity cycle(s) in late-type (FGKM) stars. We…
The HADES RV Programme with HARPS-N@TNG - GJ 3998: An early M-dwarf hosting a system of Super-Earths
L. Affer, G. Micela, M. Damasso +29
Context. M dwarfs are considered ideal targets for Doppler radial velocity searches. Nonetheless, the statistics of frequency of low-mass planets hosted by low mass stars remains p…
Is the activity level of HD 80606 influenced by its eccentric planet?
P. Figueira, A. Santerne, A. Suárez Mascareño +14
Aims: Several studies suggest that the activity level of a planet-host star can be influenced by the presence of a close-by orbiting planet. Moreover, the interaction mechanisms th…
