The evolution of discs and the epoch of formation of giant planets around solar type stars
Raffaele Gratton, Elisabetta Rigliaco
Disc evolution dictates the time for planet formation providing the raw material to build the planets' cores. Dynamical stellar masses derived from the kinematics of the gas in dis…
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…
The SPHERE infrared survey for exoplanets (SHINE) V. Full sample characterization
V. Squicciarini, S. Desidera, G. Chauvin +109
Unbiased surveys of large stellar samples are the prime means through which the prevalence of exoplanets can be derived, and crucial constraints to planet formation models can be s…
Exploration of the inner region of the system HD 142527
T. M. H. Tran, M. Langlois, O. Flasseur +6
HD 142527 is a well-studied intermediate-mass T Tauri star surrounded by a transitional disk with a large dust cavity, spiral structures, and an accreting low-mass companion. Despi…
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…
The Corona-Australis star-forming region: New insights on its formation history from detailed stellar and disk analysis
Elisabetta Rigliaco, Raffaele Gratton, Valerio Nascimbeni
The star-forming complex of Corona Australis (CrA) is one of the closest and most isolated molecular clouds. It belongs to a chain of clusters that show age gradients with distance…
(Re)mind the gap: a hiatus in star formation history unveiled by APOGEE DR17
E. Spitoni, F. Matteucci, R. Gratton +3
The analysis of several spectroscopic surveys indicates the presence of a bimodality between the disc stars in the abundance ratio space of [/Fe] versus [Fe/H]. The two stellar…
