Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): HD 34700 A unveils an inner ring
G. Columba, E. Rigliaco, R. Gratton +18
Context. The study of protoplanetary disks is fundamental to understand their evolution and interaction with the surrounding environment, and to constrain planet formation mechanis…
Jupiter-like planets might be common in a low-density environment
Raffaele Gratton, Dino Mesa, Mariangela Bonavita +6
Radial velocity surveys suggest that the Solar System may be unusual and that Jupiter-like planets have a frequency <20% around solar-type stars. However, they may be much more com…
Multiples among B stars in the Scorpius-Centaurus association
R. Gratton, V. Squicciarini, V. Nascimbeni +13
We discuss the properties of companions to B stars in the Scorpius-Centaurus association (age ~15 Myr, 181 B-stars). We gathered available data combining high contrast imaging samp…
The GAPS program at TNG XLVII: The unusual formation history of V1298 Tau
D. Turrini, F. Marzari, D. Polychroni +33
Observational data from space and ground-based campaigns reveal that the 10-30 Ma old V1298 Tau star hosts a compact and massive system of four planets. Mass estimates for the two…
AF Lep b: the lowest mass planet detected coupling astrometric and direct imaging data
D. Mesa, R. Gratton, P. Kervella +6
Aims. Using the direct imaging technique we searched for low mass companions around the star AF Lep that presents a significant proper motion anomaly (PMa) signal obtained from the…
