A first look at the protoplanet WISPIT 2 b with VLTI/GRAVITY+

GRAVITY+ Collaboration, K. Abd El Dayem, R. Abuter +116

Confirmed observations of young protoplanets actively undergoing the process of formation have remained rare to date. In this Letter, we present new insights into the nature of the…

A self-consistent orbital architecture for GG Tau A. I. Simultaneous orbital fitting of the hierarchical triple

A. Lacquement, H. Beust, G. Duchêne +4

GG Tau is a young triple system with the close pair, --, and , surrounded by a massive circumtriple disk with a large inner cavity difficult to explain in a bin…

Planetary gas gaps and kinematic signatures in the planet forming disk around WISPIT 2

Nienke van der Marel, Jochen Stadler, Andres F. Izquierdo +8

The giant planet formation process in disks of gas and dust surrounding young stars is observationally still poorly constrained. Direct detection of protoplanets within the disk re…

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…
