Analysis of the young disk around WRAY 15-1880: does it contain a primitive planetary system?
Elisabetta Rigliaco, Raffaele Gratton, Silvano Desidera +2
Observations of (giant) planets accreting material within their natal environment are crucial to constrain models for their formation. WRAY 15-1880 (aka RX J1842.9-3532) in the Cor…

Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): V721 CrA and BN CrA have wide and structured disks in polarised IR
Gabriele Columba, Elisabetta Rigliaco, Raffaele Gratton +8
We present near-infrared scattered-light observations of the disks around two stars of the Corona Australis star-forming region, V721 CrA, and BN CrA, obtained with VLT/SPHERE, in…

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 )…
