Limits on Millimeter Continuum Emission from Circumplanetary Material in the DSHARP Disks
Sean M. Andrews, William Elder, Shangjia Zhang +10
We present a detailed analysis for a subset of the high resolution (~35 mas, or 5 au) ALMA observations from the Disk Substructures at High Angular Resolution Project (DSHARP) to s…
The Architecture of the V892 Tau System: the Binary and its Circumbinary Disk
Feng Long, Sean M. Andrews, Justin Vega +11
We present high resolution millimeter continuum and CO line observations for the circumbinary disk around V892 Tau to constrain the stellar and disk properties. The total mass of t…
The 2017 May 20 stellar occultation by the elongated centaur (95626) 2002 GZ
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +56
We predicted a stellar occultation of the bright star Gaia DR1 4332852996360346368 (UCAC4 385-75921) (m= 14.0 mag) by the centaur 2002 GZ for 2017 May 20$^{\rm th}…
A search for companions via direct imaging in the DSHARP planet-forming disks
Sebastián Jorquera, Laura M. Pérez, Gaël Chauvin +10
The "Disk Substructures at High Angular Resolution Project" (DSHARP) has revealed an abundance and ubiquity of rings and gaps over a large sample of young planet-forming disks, whi…
The Radial Distribution of Dust Particles in the HL Tau Disk from ALMA and VLA Observations
Carlos Carrasco-González, Anibal Sierra, Mario Flock +13
Understanding planet formation requires to discern how dust grows in protoplanetary disks. An important parameter to measure in disks is the maximum dust grain size present. This i…
An Ideal Testbed for Planet-disk Interaction: Two Giant Protoplanets in Resonance Shaping the PDS 70 Protoplanetary Disk
Jaehan Bae, Zhaohuan Zhu, Clément Baruteau +7
While numerical simulations have been playing a key role in the studies of planet-disk interaction, testing numerical results against observations has been limited so far. With the…
Submillimeter emission associated with candidate protoplanets
Andrea Isella, Myriam Benisty, Richard Teague +4
We present the discovery of a spatially unresolved source of sub-millimeter continuum emission ( m) associated with a young planet, PDS 70 c, recently detected in H em…
New Constraints From Dust Lines On The Surface Densities Of Protoplanetary Disks
Diana Powell, Ruth Murray-Clay, Laura M. Pérez +2
We present new determinations of disk surface density, independent of an assumed dust opacity, for a sample of 7 bright, diverse protoplanetary disks using measurements of disk dus…
An Inner Disk in the Large Gap of the Transition Disk SR 24S
Paola Pinilla, Myriam Benisty, Paolo Cazzoletti +3
We report new Atacama Large Millimeter/sub-millimeter Array (ALMA) Band 3 observations at 2.75 mm of the TD around SR 24S with an angular resolution of 0.11'' 0.09''…
The Disk Substructures at High Angular Resolution Project (DSHARP): VII. The Planet-Disk Interactions Interpretation
Shangjia Zhang, Zhaohuan Zhu, Jane Huang +12
The Disk Substructures at High Angular Resolution Project (DSHARP) provides a large sample of protoplanetary disks having substructures which could be induced by young forming plan…
The Disk Substructures at High Angular Resolution Project (DSHARP) VI: Dust trapping in thin-ringed protoplanetary disks
Cornelis P. Dullemond, Tilman Birnstiel, Jane Huang +12
A large fraction of the protoplanetary disks observed with ALMA display multiple well-defined and nearly perfectly circular rings in the continuum, in many cases with substantial p…
The Disk Substructures at High Angular Resolution Project (DSHARP): II. Characteristics of Annular Substructures
Jane Huang, Sean M. Andrews, Cornelis P. Dullemond +14
The Disk Substructures at High Angular Resolution Project used ALMA to map the 1.25 millimeter continuum of protoplanetary disks at a spatial resolution of ~5 au. We present a syst…
A Close-up View of the Young Circumbinary Disk HD 142527
Y. Boehler, E. Weaver, A. Isella +4
We present ALMA observations of the 0.88 millimeter dust continuum, 13CO, and C18O J=3-2 line emission of the circumbinary disk HD142527 at a spatial resolution of about 0.25". Thi…
