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…
A closer look at the WISPIT 2 host star. Evidence for a spectroscopic binary
Cade J. Bürgy, Cade J. Bürgy, Myriam Benisty +3
While hundreds of protoplanetary discs have been studied in great detail, the detection of protoplanets still embedded in their native discs remains rare. WISPIT 2 is only the seco…
Dust characterization of the HD 163296 disk with high-resolution multi-wavelength ALMA observations
Kiyoaki Doi, Myriam Benisty, Akimasa Kataoka +10
Context. Planets form through the growth and accumulation of dust grains in protoplanetary disks. Characterizing dust properties such as size, surface density, and temperature is k…
Azimuthal molecular variations in the AB Aur planet-forming disk
Haochang Jiang, Dmitry Semenov, Myriam Benisty +5
Late infall episodes are emerging as an important driver of disk evolution. Observed as filamentary streamers in molecular lines and scattered light, such accretion perturbs disk s…
Two inner dust clumps in PDS 70. A third protoplanet traced by trojan material or a substructured inner disk?
O. Balsalobre-Ruza, V. Christiaens, N. Huélamo +21
The PDS 70 cavity hosts two confirmed directly imaged protoplanets and a third inner planet candidate at 13au, labeled PDS 70 d. Despite its Keplerian motion, its unusually blue sp…
Interpreting the scattering surface in protoplanetary disks
Massimiliano Bolchini, Giovanni Rosotti, Marion Villenave +5
In recent years, extreme adaptive optics have enabled high-resolution, high-contrast scattered-light observations of protoplanetary disks. Interpreting these observations requires…
