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…
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…
Multi techniques approach to identify and/or constrain radial velocity sub-stellar companions
F. Philipot, A. -M. Lagrange, F. Kiefer +3
Context. Although more than one thousand sub-stellar companions have already been detected with the radial velocity (RV) method, many new companions remain to be detected in the pu…
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…
An imaged 15Mjup companion within a hierarchical quadruple system
A. Chomez, V. Squicciarini, A. -M. Lagrange +20
Since 2019, the direct imaging B-star Exoplanet Abundance Study (BEAST) at SPHERE@VLT has been scanning the surroundings of young B-type stars in order to ascertain the ultimate fr…
Emission line variability of young 10-30 Mjup companions : I. The case of GQ Lup b and GSC 06214-00210 b
Dorian Demars, Mickael Bonnefoy, Catherine Dougados +10
Emission lines indicative of active accretion have been seen on a handful of low-mass companions (M < 30 MJup) to stars. Line variability is ubiquitous on stellar accretors but has…
