X-Shooter survey of disk accretion in Upper Scorpius I. Very high accretion rates at age>5 Myr
C. F. Manara, A. Natta, G. P. Rosotti +14
Determining the mechanisms that drive the evolution of protoplanetary disks is a necessary step to understand how planets form. Here we measured the mass accretion rate for young s…
Compact Disks in a High Resolution ALMA Survey of Dust Structures in the Taurus Molecular Cloud

We present a high-resolution (, au, mean sensitivity of Jy~beam at 225 GHz) snapshot survey of 32 protoplanetary disks around young stars with spe…
The newborn planet population emerging from ring-like structures in discs
G. Lodato, G. Dipierro, E. Ragusa +23
ALMA has observed a plethora of ring-like structures in planet forming discs at distances of 10-100 au from their host star. Although several mechanisms have been invoked to explai…
Hints for a Turnover at the Snow Line in the Giant Planet Occurrence Rate
Rachel B. Fernandes, Gijs D. Mulders, Ilaria Pascucci +2
The orbital distribution of giant planets is crucial for understanding how terrestrial planets form and predicting yields of exoplanet surveys. Here, we derive giant planets occurr…
High-Resolution ALMA Observations of HD100546: Asymmetric Circumstellar Ring, and Circumplanetary Disk Upper Limits
J. E. Pineda, J. Szulágyi, S. P. Quanz +7
We present long baseline Atacama Large Millimeter/submillimeter Array (ALMA) observations of the 870m dust continuum emission and CO (3-2) from the protoplanetary disk around…
Gaps and Rings in an ALMA Survey of Disks in the Taurus Star-forming Region
Feng Long, Paola Pinilla, Gregory J. Herczeg +23
Rings are the most frequently revealed substructure in ALMA dust observations of protoplanetary disks, but their origin is still hotly debated. In this paper, we identify dust subs…
An ALMA Survey of faint disks in the Chamaeleon I star-forming region: Why are some Class II disks so faint?
Feng Long, Gregory J. Herczeg, Ilaria Pascucci +6
ALMA surveys of nearby star-forming regions have shown that the dust mass in the disk is correlated with the stellar mass, but with a large scatter. This scatter could indicate eit…
Constraints from Dust Mass and Mass Accretion Rate Measurements on Angular Momentum Transport in Protoplanetary Disks
Gijs D. Mulders, Ilaria Pascucci, Carlo F. Manara +5
We investigate the relation between disk mass and mass accretion rate to constrain the mechanism of angular momentum transport in protoplanetary disks. Dust mass and mass accretion…
An ALMA Survey of CO isotopologue emission from Protoplanetary Disks in Chamaeleon I
Feng Long, Gregory J. Herczeg, Ilaria Pascucci +8
The mass of a protoplanetary disk limits the formation and future growth of any planet. Masses of protoplanetary disks are usually calculated from measurements of the dust continuu…
X-Shooter study of accretion in Chamaeleon I: II. A steeper increase of accretion with stellar mass for very low mass stars?
C. F. Manara, L. Testi, G. J. Herczeg +10
The dependence of the mass accretion rate on the stellar properties is a key constraint for star formation and disk evolution studies. Here we present a study of a sample of stars…
Resolving the planet-hosting inner regions of the LkCa 15 disk
C. Thalmann, M. Janson, A. Garufi +28
LkCa 15 hosts a pre-transitional disk as well as at least one accreting protoplanet orbiting in its gap. Previous disk observations have focused mainly on the outer disk, which is…
The Eruption of the Candidate Young Star ASASSN-15qi
Gregory J. Herczeg, Subo Dong, Benjamin J. Shappee +27
Outbursts on young stars are usually interpreted as accretion bursts caused by instabilities in the disk or the star-disk connection. However, some protostellar outbursts may not f…
The SPHERE view of the planet-forming disk around HD100546
Antonio Garufi, Sascha P. Quanz, Hans Martin Schmid +39
We image with unprecedented spatial resolution and sensitivity disk features that could be potential signs of planet-disk interaction. Two companion candidates have been claimed in…
X-Shooter study of accretion in Chamaeleon I
C. F. Manara, D. Fedele, G. J. Herczeg +1
We present the analysis of 34 new VLT/X-Shooter spectra of young stellar objects in the Chamaeleon I star forming region, together with four more spectra of stars in Taurus and two…
The evolved circumbinary disk of AC Her: a radiative transfer, interferometric and mineralogical study
M. Hillen, B. L. de Vries, J. Menu +3
We aim to constrain the structure of the circumstellar material around the post-AGB binary and RV Tauri pulsator AC Her. We want to constrain the spatial distribution of the amorph…
Probing stellar accretion with mid-infrared hydrogen lines
Elisabetta Rigliaco, I. Pascucci, G. Duchene +12
In this paper we investigate the origin of the mid-infrared (IR) hydrogen recombination lines for a sample of 114 disks in different evolutionary stages (full, transitional and deb…
A Tale of Two Stars: Interferometric Studies of Post-AGB Binaries
M. Hillen, J. Menu, B. de Vries +7
Binaries with circumbinary disks are commonly found among optically bright post-AGB stars. Although clearly linked to binary interaction processes, the formation, evolution and fat…
