Discovery of a Low-Mass Companion to the Accelerating Star HIP 53005 with Strongly Conflicting Mass Estimates
Taichi Uyama, Thayne Currie, Jerry W. Xuan +22
We present the discovery of a low-mass companion located at 0\farcs{}85 () from the early-type 1.2 Gyr-old star HIP 53005 using direct imagin…
A study of the frequency and characteristics of stellar companions and Jupiter-like planets in nearby open clusters
R. Gratton, M. Bonavita, D. Mesa +9
Observations of companions of solar-type stars in nearby young moving groups (NYMGs) show that they split into two groups: stellar and brown dwarf companions (mass ratio )…
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…
MADYS: the Manifold Age Determination for Young Stars
Vito Squicciarini, Mariangela Bonavita
The unrivalled astrometric and photometric capabilities of the Gaia mission have given new impetus to the study of young stars: both from an environmental perspective, as members o…
Results from The COPAINS Pilot Survey: four new brown dwarfs and a high companion detection rate for accelerating stars
M. Bonavita, C. Fontanive, R. Gratton +6
The last decade of direct imaging (DI) searches for sub-stellar companions has uncovered a widely diverse sample that challenges the current formation models, while highlighting th…
New binaries from the SHINE survey
M. Bonavita, R. Gratton, S. Desidera +67
We present the multiple stellar systems observed within the SpHere INfrared survey for Exoplanet (SHINE). SHINE searched for substellar companions to young stars using high contras…
