A dusty filament and turbulent CO spirals in HD135344B-SAO206462
Simon Casassus, Valentin Christiaens, Miguel Carcamo +16
Planet-disc interactions build up local pressure maxima that may halt the radial drift of protoplanetary dust, and pile it up in rings and crescents. ALMA observations of the HD135…
Planet migration, resonant locking and accretion streams in PDS70: Comparing models and data
Claudia Toci, Giuseppe Lodato, Valentin Christiaens +4
The disc surrounding PDS 70, with two directly imaged embedded giant planets, is an ideal laboratory to study planet-disc interaction. We present three-dimensional smoothed particl…
Are the spiral arms in the MWC 758 protoplanetary disc driven by a companion inside the cavity?
Josh Calcino, Valentin Christiaens, Daniel J. Price +4
Spiral arms in protoplanetary discs are thought to be linked to the presence of companions. We test the hypothesis that the double spiral arm morphology observed in the transition…
The Ophiuchus DIsc Survey Employing ALMA (ODISEA). II. The effect of stellar multiplicity on disc properties
Alice Zurlo, Lucas A. Cieza, Sebastián Pérez +9
We present Adaptive Optics (AO) near infrared (NIR) observations using VLT/NACO and Keck/NIRC2 of ODISEA targets. ODISEA is an ALMA survey of the entire population of circumstellar…
Discovery of a low-mass companion embedded in the disk of the young massive star MWC 297 with VLT/SPHERE
M. Giulia Ubeira-Gabellini, Valentin Christiaens, Giuseppe Lodato +4
We report the discovery of a low-mass stellar companion around the young Herbig Be star MWC 297. We performed multi-epoch high-contrast imaging in the near infrared (NIR) with the…
Nine localised deviations from Keplerian rotation in the DSHARP circumstellar disks: Kinematic evidence for protoplanets carving the gaps
C. Pinte, D. J. Price, F. Menard +12
We present evidence for localised deviations from Keplerian rotation, i.e., velocity "kinks", in 8 of 18 circumstellar disks observed by the DSHARP program: DoAr 25, Elias 2-27, GW…
