Constraining Turbulence in Protoplanetary Disks
, 2021 Our understanding of the formation of planets hinges on the study of protoplanetary disks. These disks of dust and gas form alongside young stars, and are the birthplace of planetary systems.

Measuring the Two-dimensional Thermal Structures of Protoplanetary Disks
The Astrophysical JournalWe present a flexible, annulus-by-annulus method to constrain the 2D thermal structure of a protoplanetary disk from optically thick spectral line emission.

The diversification and dissipation of protoplanetary disks
Astronomy & AstrophysicsProtoplanetary disk evolution exhibits trends with stellar mass, but also diversity of structure, and lifetime, with implications for planet formation and demographics. We show how varied outcomes can result from evolving structures in the inner disk that attenuate stellar soft X-rays that otherwise drive photoevaporation in the outer disk.

Tracing Pebble Drift History in Two Protoplanetary Disks with CO Enhancement
The Astrophysical JournalPebble drift is an important mechanism for supplying the materials needed to build planets in the inner region of protoplanetary disks. Thus, constraining pebble drift’s timescales and mass flux is essential to understanding planet formation history ...

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

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.
