Circumbinary and circumstellar discs around the eccentric binary IRAS 04158+2805 -- a testbed for binary-disc interaction
Enrico Ragusa, Daniele Fasano, Claudia Toci +10
IRAS~04158+2805 has long been thought to be a very low mass T-Tauri star (VLMS) surrounded by a nearly edge-on, extremely large disc. Recent observations revealed that this source…
The Anatomy of an Unusual Edge-on Protoplanetary Disk. II. Gas temperature and a warm outer region
Christian Flores, Gaspard Duchene, Schuyler Wolff +9
We present high-resolution CO and CO 2-1 ALMA observations, as well as optical and near-infrared spectroscopy, of the highly-inclined protoplanetary disk around SSTC2…
A single-armed spiral in the protoplanetary disk around HD34282 ?
J. de Boer, C. Ginski, G. Chauvin +17
During the evolution of protoplanetary disks into planetary systems we expect to detect signatures that trace mechanisms such as planet-disk interaction. Protoplanetary disks displ…
Spirals, shadows & precession in HD 100453 -- II. The hidden companion
Rebecca Nealon, Nicolás Cuello, Jean-François Gonzalez +5
The protoplanetary disc HD 100453 exhibits a curious combination of spirals, shadows and a relative misalignment between the observed outer disc and inferred inner disc. This disc…
Observations of edge-on protoplanetary disks with ALMA I. Results from continuum data
M. Villenave, F. Menard, W. R. F. Dent +15
We analyze a sample of 12 HST-selected edge-on protoplanetary disks for which the vertical extent of the emission layers can be constrained directly. We present ALMA high angular r…
Ongoing flyby in the young multiple system UX Tauri
F. Menard, N. Cuello, C. Ginski +28
We present observations of the young multiple system UX Tauri to look for circumstellar disks and for signs of dynamical interactions. We obtained SPHERE/IRDIS deep differential po…
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…
Disks Around T Tauri Stars with SPHERE (DARTTS-S) II: Twenty-one new polarimetric images of young stellar disks
Antonio Garufi, Henning Avenhaus, Sebastian Perez +8
Near-IR polarimetric images of protoplanetary disks enable us to characterize substructures that might be due to the interaction with (forming) planets. The available census is str…
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…
Spatial segregation of dust grains in transition disks. SPHERE observations of 2MASS J16083070-3828268 and RXJ1852.3-3700
M. Villenave, M. Benisty, W. R. F. Dent +27
Context. The mechanisms governing the opening of cavities in transition disks are not fully understood. Several processes have been proposed but their occurrence rate is still unkn…
A search for accreting young companions embedded in circumstellar disks: High-contrast H imaging with VLT/SPHERE
G. Cugno, S. P. Quanz, S. Hunziker +37
Aims: We want to detect and quantify observables related to accretion processes occurring locally in circumstellar disks, which could be attributed to young forming planets. We foc…
The Ring Structure in the MWC 480 Disk Revealed by ALMA
Yao Liu, Giovanni Dipierro, Enrico Ragusa +20
Gap-like structures in protoplanetary disks are likely related to planet formation processes. In this paper, we present and analyze high resolution (0.17*0.11 arcsec) 1.3 mm ALMA c…
Evolution of protoplanetary disks from their taxonomy in scattered light: spirals, rings, cavities, and shadows
Antonio Garufi, Myriam Benisty, Paola Pinilla +11
The variety of observed protoplanetary disks in polarimetric light motivates a taxonomical study to constrain their evolution and establish the current framework of this type of ob…
Dust modeling of the combined ALMA and SPHERE datasets of HD163296. Is HD163296 really a Meeus group II disk?
G. A. Muro-Arena, C. Dominik, L. B. F. M. Waters +20
Context. Multi-wavelength observations are indispensable in studying disk geometry and dust evolution processes in protoplanetary disks. Aims. We aimed to construct a 3-dimensional…
The Taurus Boundary of Stellar/Substellar (TBOSS) Survey II. Disk Masses from ALMA Continuum Observations
K. Ward-Duong, J. Patience, J. Bulger +9
We report 885m ALMA continuum flux densities for 24 Taurus members spanning the stellar/substellar boundary, with spectral types from M4 to M7.75. Of the 24 systems, 22 are dete…
The circumstellar disk HD169142: gas, dust and planets acting in concert?
A. Pohl, M. Benisty, P. Pinilla +33
HD169142 is an excellent target to investigate signs of planet-disk interaction due to the previous evidence of gap structures. We performed J-band (~1.2μm) polarized intensity…
Direct mapping of the temperature and velocity gradients in discs. Imaging the vertical CO snow line around IM Lupi
