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…
Dynamical masses for two M1 + mid-M dwarf binaries monitored during the SPHERE-SHINE survey
Beth A. Biller, Antoine Grandjean, Sergio Messina +25
We present orbital fits and dynamical masses for HIP 113201AB and HIP 36985AB, two M1 + mid-M dwarf binary systems monitored as part of the SPHERE SHINE survey. To robustly determi…
Resolving the planet-hosting inner regions of the LkCa 15 disk
C. Thalmann, M. Janson, A. Garufi +28
LkCa 15 hosts a pre-transitional disk as well as at least one accreting protoplanet orbiting in its gap. Previous disk observations have focused mainly on the outer disk, which is…
A vigorous activity cycle mimicking a planetary system in HD200466
E. Carolo, S. Desidera, R. Gratton +9
Stellar activity can be a source of radial velocity (RV) noise and can reproduce periodic RV variations similar to those produced by an exoplanet. We present the vigorous activity…
