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…

ExoplaNeT accRetion mOnitoring sPectroscopic surveY (ENTROPY) - II. Time series of Balmer line profiles of Delorme 1(AB)b

Dorian Demars, Mickaël Bonnefoy, Catherine Dougados +14

Accretion processes in the planetary-mass regime remain poorly constrained, yet they strongly influence planet formation, evolution, and the composition of circumplanetary disks (C…

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…

Protoplanetary disk insights from the first ERIS/APP survey at 4 μm

F. Maio, V. Roccatagliata, D. Fedele +17

We present high-contrast imaging observations of seven protoplanetary disks at 4um using the ERIS on the VLT. This study focuses on detecting scattered light from micron-sized dust…

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 )…
