TOSC: an algorithm for the tomography of spotted transit chords
Gaetano Scandariato, Valerio Nascimbeni, Antonio Francesco Lanza +3
Photometric observations of planetary transits may show localized bumps, called transit anomalies, due to the possible crossing of photospheric starspots. The aim of this work is t…
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…
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…
The GAPS programme with HARPS-N at TNG XI. Pr~0211 in M~44: the first multi-planet system in an open cluster
L. Malavolta, V. Nascimbeni, G. Piotto +45
Open cluster (OC) stars share the same age and metallicity, and, in general, their age and mass can be estimated with higher precision than for field stars. For this reason, OCs ar…
The GAPS Programme with HARPS-N at TNG. VII. Putting exoplanets in the stellar context: magnetic activity and asteroseismology of Bootis A
F. Borsa, G. Scandariato, M. Rainer +34
Aims. We observed the Boo system with the HARPS-N spectrograph to test a new observational strategy aimed at jointly studying asteroseismology, the planetary orbit, and star-pl…
Stellar parameters of early M dwarfs from ratios of spectral features at optical wavelengths
J. Maldonado, L. Affer, G. Micela +29
(Abridged) Low-mass stars have been recognised as promising targets in the search for rocky, small planets with the potential of supporting life. Doppler search programmes using hi…
