Demographics of Protoplanetary Disks: A Simulated Population of Edge-on Systems
Isabel Angelo, Gaspard Duchêne, Karl Stapelfeldt +9
The structure of protoplanetary disks plays an essential role in planet formation. Disks that are highly inclined, or ''edge-on'', are of particular interest since their geometry p…
Mapping Protoplanetary Disk Vertical Structure with CO Isotopologue Line Emission
Charles J. Law, Richard Teague, Karin I. Öberg +21
High spatial resolution observations of CO isotopologue line emission in protoplanetary disks at mid-inclinations (30-75°) allow us to characterize the gas structure in…
Observational constraints on disc sizes in protoplanetary discs in multiple systems in the Taurus region. II. Gas disc sizes
A. A. Rota, C. F. Manara, A. Miotello +13
The formation of multiple stellar systems is a natural by-product of the star-formation process, and its impact on the properties of protoplanetary discs and on the formation of pl…
The Anatomy of an Unusual Edge-on Protoplanetary Disk I. Dust Settling in a Cold Disk
S. Wolff, G. Duchêne, K. Stapelfeldt +7
As the earliest stage of planet formation, massive, optically thick, and gas rich protoplanetary disks provide key insights into the physics of star and planet formation. When view…
Investigating the nature of the extended structure around the Herbig star RCrA using integral field and high-resolution spectroscopy
E. Rigliaco, R. Gratton, D. Mesa +24
We present a detailed analysis of the extended structure detected around the young and close-by Herbig Ae/Be star RCrA. This is a young triple system with an intermediate mass cent…
Exploring the RCrA environment with SPHERE: Discovery of a new stellar companion
D. Mesa, M. Bonnefoy, R. Gratton +39
Aims. R Coronae Australis (R CrA) is the brightest star of the Coronet nebula of the Corona Australis (CrA) star forming region. It has very red colors, probably due to dust absorp…
Mapping of shadows cast on a protoplanetary disk by a close binary system
V. D'Orazi, R. Gratton, S. Desidera +47
For a comprehensive understanding of planetary formation and evolution, we need to investigate the environment in which planets form: circumstellar disks. Here we present high-cont…
Observability of Forming Planets and their Circumplanetary Disks I. -- Parameter Study for ALMA
J. Szulágyi, G. van der Plas, M. R. Meyer +5
We present mock observations of forming planets with ALMA. The possible detections of circumplanetary disks (CPDs) were investigated around planets of Saturn, 1, 3, 5, and 10 Jupit…
Belt(s) of debris resolved around the Sco-Cen star HIP 67497
M. Bonnefoy, J. Milli, F. Ménard +15
In 2015, we initiated a survey of Scorpius-Centaurus A-F stars that are predicted to host warm-inner and cold-outer belts of debris similar to the case of the system HR~8799. The s…
A cavity and further radial substructures in the disk around HD~97048
G. van der Plas, C. M. Wright, F. Ménard +9
Context: Gaps, cavities and rings in circumstellar disks are signposts of disk evolution and planet-disk interactions. We follow the recent suggestion that Herbig Ae/Be disks with…
Dust masses of disks around 8 Brown Dwarfs and Very Low-Mass Stars in Upper Sco OB1 and Ophiuchus
G. van der Plas, F. Menard, K. Ward-Duong +6
We present the results of ALMA band 7 observations of dust and CO gas in the disks around 7 objects with spectral types ranging between M5.5 and M7.5 in Upper Scorpius OB1, and one…
Variability in the CO ro-vibrational lines from HD163296
Rosina P. Hein Bertelsen, I. Kamp, G. van der Plas +4
We present for the first time a direct comparison of multi-epoch (2001-2002 and 2012) CO ro-vibrational emission lines from HD163296. We find that both the line shapes and the FWHM…
An ALMA Survey for Disks Orbiting Low-Mass Stars in the TW Hya Association
David R. Rodriguez, Gerrit van der Plas, Joel H. Kastner +5
We have carried out an ALMA survey of 15 confirmed or candidate low-mass (<0.2M) members of the TW Hya Association (TWA) with the goal of detecting molecular gas in the for…
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…
The structure of disks around Herbig Ae/Be stars as traced by CO ro-vibrational emission
G. van der Plas, M. E. van den Ancker, L. B. F. M. Waters +1
We study the emission and absorption of CO ro-vibrational lines in the spectra of intermediate mass pre-main-sequence stars with the aim to determine both the spatial distribution…
CO gas inside the protoplanetary disk cavity in HD 142527: disk structure from ALMA
Sebastian Perez, S. Casassus, F. Ménard +6
Inner cavities and annular gaps in circumstellar disks are possible signposts of giant planet formation. The young star HD 142527 hosts a massive protoplanetary disk with a large c…
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…
Spiral arms in the disk of HD 142527 from CO emission lines with ALMA
Valentin Christiaens, Simon Casassus, Sebastian Perez +2
In view of both the size of its gap and the previously reported asymmetries and near-infrared spiral arms, the transition disk of the Herbig Fe star HD 142527 constitutes a remarka…

Observations of gas flows inside a protoplanetary gap
