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.

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 ...

Shadow-induced Warps in Protoplanetary Disks
The Astrophysical Journal LettersShadows are commonly observed in protoplanetary disks in near-infrared (NIR) and (sub)millimeter images, often cast by misaligned inner disks or other obscuring material.

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.
