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…
Precise Masses in the WASP-47 System
Andrew Vanderburg, Juliette C. Becker, Lars A. Buchhave +32
We present precise radial velocity observations of WASP-47, a star known to host a hot Jupiter, a distant Jovian companion, and, uniquely, two additional transiting planets in shor…
The Gaia-ESO Survey and CSI 2264: Substructures, disks, and sequential star formation in the young open cluster NGC 2264
L. Venuti, L. Prisinzano, G. G. Sacco +21
We explore the structure and star formation history of the open cluster NGC 2264 (~3 Myr). We combined spectroscopic data from the Gaia-ESO Survey (GES) with multi-wavelength photo…
The GAPS Project: First Results
S. Benatti, R. Claudi, S. Desidera +14
The GAPS programme is an Italian project aiming to search and characterize extra-solar planetary systems around stars with different characteristics (mass, metallicity, environment…
HADES RV Programme with HARPS-N at TNG: V. A super-Earth on the inner edge of the habitable zone of the nearby M-dwarf GJ 625
A. Suárez Mascareño, J. I. González Hernández, R. Rebolo +27
We report the discovery of a super-Earth orbiting at the inner edge of the habitable zone of the star GJ 625 based on the analysis of the radial-velocity (RV) time series from the…
Multiple kinematical populations in Vela OB2 from Gaia DR1 data
F. Damiani, L. Prisinzano, R. D. Jeffries +3
Recent results using radial-velocity measurements from the Gaia-ESO Survey have led to the discovery of multiple kinematic populations across the Vela OB2 association. We present h…
