Viscously Stirring Particle Disks into Lorentzians and Gaussians to Infer Dynamical and Collisional Masses (ARKS XIII)

Eugene Chiang, Tim D. Pearce, Marija R. Jankovic +16

Disks (Keplerian or otherwise, particulate or fluid) are often assumed to have densities that drop off vertically as Gaussians. Recent mm-wave imaging of circumstellar debris disks…

A radially broad collisional cascade in the debris disk of Ophiuchi observed by JWST

Yinuo Han, Mark Wyatt, Kate Y. L. Su +13

The A1V star Oph, at a distance of 29.7 pc, is known from Spitzer imaging to host a debris disk with a large radial extent and from its spectral energy distribution to host inn…

Detailed Microwave Continuum Spectra from Bright Protoplanetary Disks in Taurus

Caleb Painter, Sean M. Andrews, Claire J. Chandler +9

We present new observations that densely sample the microwave (4-360 GHz) continuum spectra from eight young systems in the Taurus region. Multi-component, empirical model prescrip…

REsolved ALMA and SMA Observations of Nearby Stars (REASONS): A population of 74 resolved planetesimal belts at millimetre wavelengths

L. Matrà, S. Marino, D. J. Wilner +19

Planetesimal belts are ubiquitous around nearby stars, and their spatial properties hold crucial information for planetesimal and planet formation models. We present resolved dust…

Evidence for Non-zero Turbulence in the Protoplanetary disc around IM Lup

Kevin Flaherty, A. Meredith Hughes, Jacob B. Simon +6

The amount of turbulence in protoplanetary discs around young stars is critical for determining the efficiency, timeline, and outcomes of planet formation. It is also difficult to…

A Uniform Analysis of Debris Disks with the Gemini Planet Imager II: Constraints on Dust Density Distribution Using Empirically-Informed Scattering Phase Functions

Justin Hom, Jennifer Patience, Christine H. Chen +40

Spatially-resolved images of debris disks are necessary to determine disk morphological properties and the scattering phase function (SPF) which quantifies the brightness of scatte…

Constraints on Planetesimal Collision Models in Debris Disks

Meredith A. MacGregor, David J. Wilner, Claire Chandler +6

Observations of debris disks offer a window into the physical and dynamical properties of planetesimals in extrasolar systems through the size distribution of dust grains. In parti…

Millimeter Emission Structure in the first ALMA Image of the AU Mic Debris Disk

Meredith A. MacGregor, David J. Wilner, Katherine A. Rosenfeld +9

We present 1.3 millimeter ALMA Cycle 0 observations of the edge-on debris disk around the nearby, ~10 Myr-old, M-type star AU Mic. These observations obtain 0.6 arcsec (6 AU) resol…

A Resolved Millimeter Emission Belt in the AU Mic Debris Disk

David J. Wilner, Sean M. Andrews, Meredith A. MacGregor +1

We present imaging observations at 1.3 millimeters of the debris disk surrounding the nearby M-type flare star AU Mic with beam size 3 arcsec (30 AU) from the Submillimeter Array.…

Millimeter Imaging of the beta Pictoris Debris Disk: Evidence for a Planetesimal Belt

David J. Wilner, Sean M. Andrews, A. Meredith Hughes

We present observations at 1.3 millimeters wavelength of the beta Pictoris debris disk with beam size 4.3 x 2.6 arcsec (83 x 50 AU) from the Submillimeter Array. The emission shows…
