JWST/MIRI Imaging Search for Kinematically Detected Protoplanetary Candidates
G. Cugno, M. Benisty, R. Teague +32
Kinematic perturbations observed with ALMA in CO line emission provide evidence for a population of embedded giant protoplanets shaping the structure of protoplanetary disks. We pr…
Multi-epoch scattered-light analysis of HD 135344B: new evidence for a spiral-driving protoplanet
J. Latour, V. Christiaens, O. Absil +17
The HD 135344B (SAO 206462) disk exhibits strong signposts of planet formation. ALMA images in the sub-mm revealed a gap-crossing dust filament whose position coincides with a twis…
Anatomy of a Fall: Stationary and super-Keplerian spiral arms generated by accretion streamers in protostellar discs
Josh Calcino, Daniel J. Price, Thomas Hilder +3
Late-stage infall onto evolved protoplanetary discs is an important source of material and angular momentum replenishment, and disc substructures. In this paper we used 3D smoothed…
Azimuthal temperature variations in ISO-Oph2 from multi-frequency ALMA observations
Simon Casassus, Lucas Cieza, Miguel Cárcamo +10
Environmental effects, such as stellar fly-bys and external irradiation, are thought to affect the evolution of protoplanetary disks in clustered star formation. Previous ALMA imag…
Observational Signatures of Circumbinary Discs I: Kinematics
Josh Calcino, Daniel J. Price, Christophe Pinte +5
We present five morphological and kinematic criteria to aid in asserting the binary nature of a protoplanetary disc, based on 3D hydrodynamical simulations of circumbinary discs po…
Confirmation and Keplerian motion of the gap-carving protoplanet HD 169142 b
Iain Hammond, Valentin Christiaens, Daniel J. Price +4
We present the re-detection of a compact source in the face-on protoplanetary disc surrounding HD 169142, using VLT/SPHERE data in YJH bands. The source is found at a separation of…
Kinematic and thermal signatures of the directly imaged protoplanet candidate around Elias 2-24
Christophe Pinte, Iain Hammond, Daniel J. Price +9
We report kinematic and thermal signatures associated with the directly imaged protoplanet candidate in the Elias 2-24 disc. Using the DSHARP ALMA observations of the CO J=2…
The Origin of the Doppler-flip in HD 100546: a large scale spiral arm generated by an inner binary companion
Brodie J. Norfolk, Christophe Pinte, Josh Calcino +9
Companions at sub-arcsecond separation from young stars are difficult to image. However their presence can be inferred from the perturbations they create in the dust and gas of pro…
External or internal companion exciting the spiral arms in CQ Tau?
Iain Hammond, Valentin Christiaens, Daniel J. Price +9
We present new high-contrast images in near-infrared wavelengths ( = 1.04, 1.24, 1.62, 2.18 and 3.78m) of the young variable star CQ Tau, aiming to constrain the presence of…
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…
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…
The widest H survey of accreting protoplanets around nearby transition disks
A. Zurlo, G. Cugno, M. Montesinos +6
The mechanisms of planet formation are still under debate. We know little about how planets form, even if more than 4000 exoplanets have been detected to date. Recent investigation…

Karina Maucó, Johan Olofsson, Hector Canovas +10
We present polarized light observations of the transitional disk around Sz 91 acquired with VLT/NaCo at (1.7m) and (2.2m) bands. We resolve the disk and detect pola…
Flybys in protoplanetary discs: II. Observational signatures
Nicolás Cuello, Fabien Louvet, Daniel Mentiplay +14
Tidal encounters in star clusters perturb discs around young protostars. In Cuello et al. (2019a, Paper I) we detailed the dynamical signatures of a stellar flyby in both gas and d…
Signatures of an eccentric disc cavity: Dust and gas in IRS 48
Josh Calcino, Daniel J. Price, Christophe Pinte +5
We test the hypothesis that the disc cavity in the `transition disc' Oph IRS 48 is carved by an unseen binary companion. We use 3D dust-gas smoothed-particle hydrodynamics simulati…
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…
