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…
Kinematic detection of a planet carving a gap in a protoplanetary disc
C. Pinte, G. van der Plas, F. Menard +10
We still do not understand how planets form, or why extra-solar planetary systems are so different from our own solar system. But the last few years have dramatically changed our v…
Circumbinary, not transitional: On the spiral arms, cavity, shadows, fast radial flows, streamers and horseshoe in the HD142527 disc
Daniel J. Price, Nicolas Cuello, Christophe Pinte +13
We present 3D hydrodynamical models of the HD142527 protoplanetary disc, a bright and well studied disc that shows spirals and shadows in scattered light around a 100 au gas cavity…
A compact concentration of large grains in the HD142527 protoplanetary dust trap
Simon Casassus, Chris Wright, Sebastian Marino +11
A pathway to the formation of planetesimals, and eventually giant planets, may occur in concentrations of dust grains trapped in pressure maxima. Dramatic crescent-shaped dust conc…
Accretion kinematics through the warped transition disk in HD142527 from resolved CO(6-5) observations
Simon Casassus, Sebastian Marino, Sebastian Perez +10
The finding of residual gas in the large central cavity of the HD142527 disk motivates questions on the origin of its non-Keplerian kinematics, and possible connections with planet…
Spatially resolved HCN J=4--3 and CS J=7--6 emission from the disk around HD 142527
G. van der Plas, S. Casassus, F. Menard +4
The disk around HD 142527 attracts a lot of attention, amongst others because of its resolved (sub) mm dust continuum that is concentrated into a horseshoe-shape towards the north…
