Ringed Substructure and a Gap at 1 AU in the Nearest Protoplanetary Disk
We present long-baseline Atacama Large Millimeter/submillimeter Array (ALMA) observations of the 870 micron continuum emission from the nearest gas-rich protoplanetary disk, around TW Hya, that traceExpand
Dust Filtration by Planet-induced Gap Edges: Implications for Transitional Disks
By carrying out two-dimensional two-fluid global simulations, we have studied the response of dust to gap formation by a single planet in the gaseous component of a protoplanetary disk—the so-calledExpand

The eccentricity distributions of an unprecedented large and homogeneous sample of 698 Kepler planets are derived and a dichotomy in eccentricities is discovered: the systems with single transiting planets, which make up half of the sample, have a large mean eccentricity, whereas the multiples are on nearly circular orbits.

The Disk Substructures at High Angular Resolution Project (DSHARP): I. Motivation, Sample, Calibration, and Overview
We introduce the Disk Substructures at High Angular Resolution Project (DSHARP), one of the initial Large Programs conducted with the Atacama Large Millimeter/submillimeter Array (ALMA). The primaryExpand
The Hot Inner Disk of FU Orionis
We have constructed a detailed radiative transfer disk model which reproduces the main features of the spectrum of the outbursting young stellar object FU Orionis from ~4000 A to ~8 μm. Using anExpand
Nonsteady Accretion in Protostars
Observations indicate that mass accretion rates onto low-mass protostars are generally lower than the rates of infall to their disks; this suggests that much of the protostellar mass must be accretedExpand
The Disk Substructures at High Angular Resolution Project (DSHARP): II. Characteristics of Annular Substructures
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 systematic analysis ofExpand
Observational Signatures of Planets in Protoplanetary Disks II: Spiral Arms Observed in Scattered Light Imaging Can be Induced by Planets
Using 3D global hydro simulations coupled with radiative transfer calculations, we study the appearance of density waves induced by giant planets in direct imaging observations at near infraredExpand
Accreting Circumplanetary Disks: Observational Signatures
I calculate the spectral energy distributions of accreting circumplanetary disks using atmospheric radiative transfer models. Circumplanetary disks only accreting at 10–10 M ☉ yr–1 around a 1 MJExpand
The Disk Substructures at High Angular Resolution Project (DSHARP): VII. The Planet-Disk Interactions Interpretation.
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 planets. To explore theExpand
