Astro-photometric study of M37 with Gaia and wide-field ugi-imaging

M. Griggio, L. R. Bedin, R. Raddi +15

We present an astrometric and photometric wide-field study of the Galactic open star cluster M37 (NGC 2099). The studied field was observed with ground-based images covering a regi…

The GAPS Programme with HARPS-N at TNG. XXXV. Fundamental properties of transiting exoplanet host stars

K. Biazzo, V. D'Orazi, S. Desidera +38

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…

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…

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…

The GAPS Programme with HARPS-N at TNG XV. A substellar companion around a K giant star identified with quasi-simultaneous HARPS-N and GIANO measurements

E. González - Álvarez, L. Affer, G. Micela +34

Context. Identification of planetary companions of giant stars is made difficult because of the astrophysical noise, that may produce radial velocity (RV) variations similar to tho…

GIANO-TNG spectroscopy of red supergiants in the young star cluster RSGC3

L. Origlia, E. Oliva, N. Sanna +17

The Scutum complex in the inner disk of the Galaxy has a number of young star clusters dominated by red supergiants that are heavily obscured by dust extinction and observable only…
