A Streamer Driving Misalignment in the Circumtriple Disk of GW Ori
Maria Galloway-Sprietsma, Jaehan Bae, Toni Phillips +5
GW Orionis is a triple stellar system with a disk featuring three misaligned dust rings. We present ALMA molecular line data of CO isotopologues, revealing a streamer feeding the d…
Diverse dust vertical height and settling strength conditions in protoplanetary discs
Juanita Antilen, Paola Pinilla, Dafa Li +5
The settling of dust particles plays a critical role in the growth and dynamics of dust grains. We performed a detailed modeling of the ALMA continuum substructures for six highly…
Probing dust properties through polarized scattered-light images of a sample of ring-shaped protoplanetary disks
Maxime Roumesy, François Ménard, Gaspard Duchêne +2
The evolution of protoplanetary disks, especially in the early stages of planetary formation, as dust grows, is the cornerstone of the birth of planets. The mechanisms involved in…
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 VLT/ERIS grating vector Apodizing Phase Plate coronagraph
M. A. Kenworthy, F. A. Dannert, J. Hayoz +29
We describe the design, laboratory manufacture, and on-sky testing of the grating vector apodizing phase plate (gvAPP) coronagraph for the Enhanced Resolution Imager and Spectrogra…
Direct spectroscopic confirmation of the young embedded proto-planet WISPIT 2c
Chloe Lawlor, Richelle F. van Capelleveen, Guillaume Bourdarot +18
WISPIT 2 is a nearby young star with a multi-ringed disk which was recently confirmed to host a ~4.9 MJup gas giant planet embedded in a large (60 au) gap at a radial separation of…
