Unlocking a Bayesian View on Protoplanetary Disks [PDF]

Protoplanetary disks are a natural by-product of the star-formation process. These disks of dust and gas orbit the emerging star and are the birthplace of planets.

Evolution of protoplanetary disks [PDF]

, 2009
In this review I gave an overview of the structure and evolution of protoplanetary disks, and how the evolution of dust affects this. This is an important topic because these determine the conditions under which planets are formed, or were formed in our ...

The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO). I. Program Overview and Summary of First Results

The Astrophysical Journal
We present the Atacama Large Millimeter/submillimeter Array Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO), a large program of the ALMA. AGE-PRO aims to systematically trace the evolution of gas disk mass and size throughout the lifetime of ...

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

The Astronomical Journal
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 on grain size.

exoALMA. I. Science Goals, Project Design, and Data Products

The Astrophysical Journal Letters
Planet formation is a hugely dynamic process requiring the transport, concentration, and assimilation of gas and dust to form the first planetesimals and cores.

On Kinematic Measurements of Self-gravity in Protoplanetary Disks

The Astrophysical Journal
Using controlled injection and recovery experiments, we devised an analysis prescription to assess the quality of dynamical measurements of protoplanetary disk gas masses based on resolved (CO) spectral line data, given observational limitations ...

The Carbon Isotopic Ratio and Planet Formation

The Astrophysical Journal
We present the first detection of ^13 CCH in a protoplanetary disk (TW Hya). Using observations of C _2 H, we measure CCH/ ^13 CCH = 65 ± 20 gas with a CO isotopic ratio of ^12 CO/ ^13 CO = 21 ± 5.

exoALMA XXII: A Two-dimensional Atlas of Deviations from Keplerian Disks

The Astrophysical Journal Letters
Protoplanetary disks are the birthplaces of planetary systems, and deviations from Keplerian rotation imprinted in disk gas kinematics serve as key tracers of physical processes and the presence of protoplanets within disks.

JWST Imaging of Edge-on Protoplanetary Disks. II. Appearance of Edge-on Disks with a Tilted Inner Region: Case Study of IRAS04302+2247

The Astrophysical Journal
We present James Webb Space Telescope imaging from 2 to 21 μ m of the edge-on protoplanetary disk around the embedded young star IRAS04302+2247. The structure of the source shows two reflection nebulae separated by a dark lane.
