Mapping of shadows cast on a protoplanetary disk by a close binary system
V. D'Orazi, R. Gratton, S. Desidera +47
For a comprehensive understanding of planetary formation and evolution, we need to investigate the environment in which planets form: circumstellar disks. Here we present high-cont…
The GAPS Programme with HARPS-N at TNG XVIII. Two new giant planets around the metal-poor stars HD 220197 and HD 233832
D. Barbato, A. Sozzetti, K. Biazzo +40
Statistical studies of exoplanets have shown that giant planets are more commonly hosted by metal-rich dwarf stars than low-metallicity ones, while such a correlation is not eviden…
Exploring the realm of scaled Solar System analogs with HARPS
D. Barbato, A. Sozzetti, S. Desidera +10
The assessment of the frequency of planetary systems reproducing the Solar System's architecture is still an open problem. Detailed study of multiplicity and architecture is genera…
The GAPS Programme with HARPS-N at TNG XVII. Line profile indicators and kernel regression as diagnostics of radial-velocity variations due to stellar activity in solar-like stars
A. F. Lanza, L. Malavolta, S. Benatti +35
Stellar activity is the ultimate source of radial-velocity (RV) noise in the search for Earth-mass planets orbiting late-type main-sequence stars. We analyse the performance of fou…
The HADES RV Programme with HARPS-N@TNG VIII. Gl15A: A multiple wide planetary system sculpted by binary interaction
M. Pinamonti, M. Damasso, F. Marzari +28
We present 20 years of radial velocity (RV) measurements of the M1 dwarf Gl15A, combining 5 years of intensive RV monitoring with the HARPS-N spectrograph with 15 years of archival…
The GAPS Programme with HARPS-N at TNG XVI: Measurement of the Rossiter-McLaughlin effect of the transiting planetary systems HAT-P-3, HAT-P-12, HAT-P-22, WASP-39 and WASP-60
L. Mancini, M. Esposito, E. Covino +43
We characterised five transiting planetary systems (HAT-P-3, HAT-P-12, HAT-P-22, WASP-39 and WASP-60) and determined their sky-projected planet orbital obliquity through the measur…
Eyes on K2-3: A system of three likely sub-Neptunes characterized with HARPS-N and HARPS
M. Damasso, A. S. Bonomo, N. Astudillo-Defru +67
M-dwarf stars are promising targets for identifying and characterizing potentially habitable planets. K2-3 is a nearby (45 pc), early-type M dwarf hosting three small transiting pl…
An ultra-short period rocky super-Earth with a secondary eclipse and a Neptune-like companion around K2-141
Luca Malavolta, Andrew W. Mayo, Tom Louden +44
Ultra-short period (USP) planets are a class of low mass planets with periods shorter than one day. Their origin is still unknown, with photo-evaporation of mini-Neptunes and in-si…
