Exoplanetary properties depend on stellar properties: to know the planet with accuracy and precision it is necessary to know the star as accurately and precisely as possible. Our i…
A new photometric and dynamical study of the eclipsing binary star HW Virginis
S. B. Brown-Sevilla, V. Nascimbeni, L. Borsato +12
A growing number of eclipsing binary systems of the "HW Vir" kind (i. e., composed by a subdwarf-B/O primary star and an M dwarf secondary) show variations in their orbital period,…
HADES RV programme with HARPS-N at TNG XIV. A candidate super-Earth orbiting the M-dwarf GJ 9689 with a period close to half the stellar rotation period
J. Maldonado, A. Petralia, M. Damasso +27
Context. It is now well-established that small, rocky planets are common around low-mass stars. However, the detection of such planets is challenged by the short-term activity of t…
Photometric rotation periods for 107 M dwarfs from the APACHE survey
P. Giacobbe, M. Benedetto, M. Damasso +13
We present rotation period measurements for 107 M dwarfs in the mass range observed within the context of the APACHE photometric survey. We measure rotation per…
A possibly inflated planet around the bright, young star DS Tuc A

The origin of the observed diversity of planetary system architectures is one of the main topic of the exoplanetary research. The detection of a statistically significant sample of…
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…
Mapping of shadows cast on a protoplanetary disk by a close binary system

HADES RV Programme with HARPS-N at TNG VI. GJ 3942 b behind dominant activity signals
M. Perger, I. Ribas, M. Damasso +29
Short- to mid-term magnetic phenomena on the stellar surface of M-type stars cannot only resemble the effects of planets in radial velocity data, but also may hide them. We analyze…
