Multi-wavelength Constraints on Dust Dynamics and Size Evolution in Protoplanetary Disk Rings. II. Observational Implications

Linhan Yang, Ya-Ping Li, Ruobing Dong +6

Spatially resolved dust rings in protoplanetary disks are widely used to infer disk and dust physics from multi-wavelength continuum observations. Their interpretation, however, of…

Multi-wavelength ALMA Imaging of HD 34282: Dust-trapping Signatures of a Vortex Candidate

Xiaoyi Ma, Fangyuan Yu, Ruobing Dong +8

Azimuthal arcs in millimeter continuum emission from protoplanetary disks are often attributed to dust-trapping vortices, but definitive observational confirmation of vortices rema…

Probing Dust in the MWC 480 Disk from Millimeter to Centimeter Wavelengths

Yangfan Shi, Feng Long, Enrique Macías +12

We present deep, high-resolution (100 mas) Karl G. Jansky Very Large Array (VLA) Ka-band (9.1 mm) observations of the disk around MWC 480, and infer dust properties through a…

ALMA 873 m Polarization Observations of the PDS~70 Disk

Hauyu Baobab Liu, Kiyoaki Doi, Simon Casassus +4

At a 112.4 pc distance, the PDS70 protoplanetary disk is a rare case that has been confirmed to host two accreting planets. This makes it the most important laboratory for studying…

VLT/MUSE Detection of the AB Aurigae b Protoplanet with Spectroscopy

Thayne Currie, Jun Hashimoto, Yuhiko Aoyama +6

We analyze high-contrast, medium-spectral-resolution observations of the star AB Aurigae using the Very Large Telescope's Multi Unit Spectroscopic Explorer (MUSE). In m…

JVLA Measurement of Grain Size in the Compact Dust Ring around Class I Protostar WL 17

Jun Hashimoto, Hauyu Baobab Liu, Ruobing Dong +2

The maximum grain size in protoplanetary disks is a critical parameter for planet formation, as the efficiency of mechanisms like streaming instability and pebble accretion depend…

Mapping the merging zone of late infall in the AB Aur planet-forming system

Jessica Speedie, Ruobing Dong, Richard Teague +10

Late infall events challenge the traditional view that planet formation occurs without external influence. Here we present deep ALMA CO and SO observ…

Multi-wavelength Constraints on Dust Dynamics and Size Evolution in Protoplanetary Disk Rings. I. Method

Linhan Yang, Ya-Ping Li, Ruobing Dong +3

Observations with the Atacama Large Millimeter/submillimeter Array (ALMA) and the Jansky Very Large Array (JVLA) have revealed many dust rings in protoplanetary disks, often interp…

Predictions of Dust Continuum Emission from a Potential Circumplanetary Disk: A Case Study of the Planet Candidate AB Aurigae b

Yuhito Shibaike, Jun Hashimoto, Ruobing Dong +3

Gas accreting planets embedded in protoplanetary disks are expected to show dust thermal emission from their circumplanetary disks (CPDs). However, a recently reported gas accretin…

Gravitational instability in a planet-forming disk

Jessica Speedie, Ruobing Dong, Cassandra Hall +7

The canonical theory for planet formation in circumstellar disks proposes that planets are grown from initially much smaller seeds. The long-considered alternative theory proposes…

First JVLA Radio Observation on PDS70

Hauyu Baobab Liu, Simon Casassus, Ruobing Dong +3

PDS~70 is a protoplanetary system that hosts two actively accreting gas giants, namely PDS~70b and PDS~70c. The system has a 60--100 au dusty ring that has been resolved by A…

Forming localized dust concentrations in a dust ring: DM Tau case study

Hauyu Baobab Liu, Takayuki Muto, Mihoko Konishi +8

The previous, high angular resolution 225 GHz (1.3 mm) continuum observations on the transitional disk DM Tau have resolved an outer ring at 20-120 au radii that is weakly az…

Shadowing in the protoplanetary disk of ZZ Tau IRS with HST

Jun Hashimoto, Ruobing Dong, Takayuki Muto +2

An inner component misaligned from an outer component in a protoplanetary disk can result in the former casting shadows on the latter. We present a new instance of shadowing on the…

Spiral Arms in Disks: Planets or Gravitational Instability?

Ruobing Dong, Joan R. Najita, Sean Brittain

Spiral arm structures seen in scattered light observations of protoplanetary disks can potentially serve as signposts of planetary companions. They can also lend unique insights in…

Spiral Structure and Differential Dust Size Distribution in the LkHa 330 Disk

E. Akiyama, J. Hashimoto, H. B. Liu +58

Dust trapping accelerates the coagulation of dust particles, and thus it represents an initial step toward the formation of planetesimals. We report -band (1.6 um) linear polari…

Spiral Arms in Gravitationally Unstable Protoplanetary Disks as Imaged in Scattered Light

Ruobing Dong, Cassandra Hall, Ken Rice +1

Combining 3D smoothed-particle hydrodynamics and Monte Carlo radiative transfer calculations, we examine the morphology of spiral density waves induced by gravitational instability…
