The GAPS Programme with HARPS-N@TNG XII: Characterization of the planetary system around HD108874
S. Benatti, S. Desidera, M. Damasso +36
In order to understand the observed physical and orbital diversity of extrasolar planetary systems, a full investigation of these objects and of their host stars is necessary. With…
GIARPS: the unique VIS-NIR high precision radial velocity facility in this world
Riccardo Claudi, Serena Benatti, Ilaria Carleo +30
GIARPS (GIAno & haRPS) is a project devoted to have on the same focal station of the Telescopio Nazionale Galileo (TNG) both the high resolution spectrographs HARPS-N (VIS) and GIA…
The HADES RV Programme with HARPS-N@TNG II. Data treatment and simulations
M. Perger, A. García-Piquer, I. Ribas +30
The distribution of exoplanets around low-mass stars is still not well understood. Such stars, however, present an excellent opportunity of reaching down to the rocky and habitable…
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…
Kepler-21b: A rocky planet around a V = 8.25 magnitude star
Mercedes Lopez-Morales, Raphaelle D. Haywood, Jeffrey L. Coughlin +36
HD 179070, aka Kepler-21, is a V = 8.25 F6IV star and the brightest exoplanet host discovered by Kepler. An early detailed analysis by Howell et al. (2012) of the first thirteen mo…
The Orbit and Mass of the Third Planet in the Kepler-56 System
Oderah Justin Otor, Benjamin T. Montet, John Asher Johnson +20
While the vast majority of multiple-planet systems have their orbital angular momentum axes aligned with the spin axis of their host star, Kepler-56 is an exception: its two transi…
