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…
Non-Keplerian spirals, a gas-pressure dust trap and an eccentric gas cavity in the circumbinary disc around HD 142527
Himanshi Garg, Christophe Pinte, Valentin Christiaens +7
We present ALMA observations of the CO, CO, CO J=2-1 transitions and the 1.3\,mm continuum emission for the circumbinary disc around HD 142527, at an angular r…
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 Carina High-Contrast Imaging Project for massive Stars (CHIPS) I. Methodology and proof of concept on QZ Car ( HD93206)
A. Rainot, M. Reggiani, H. Sana +13
Massive stars like company. However, low-mass companions have remained extremely difficult to detect at angular separations () smaller than 1" (~1000-3000 au considering typical…
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…
