Chemistry of Complex Organic Molecules in the V883 Ori Disk Revealed by ALMA Band 3 Observations

The Astronomical Journal
Complex organic molecules (COMs) in protoplanetary disks are key to understanding the origin of volatiles in comets in our solar system, yet the chemistry of COMs in protoplanetary disks remains poorly understood.

MINDS. JWST/MIRI Reveals a Dynamic Gas-rich Inner Disk inside the Cavity of SY Cha

The Astrophysical Journal
SY Cha is a T Tauri star surrounded by a protoplanetary disk with a large cavity seen in the millimeter continuum but has the spectral energy distribution of a full disk.

Carbon In Protoplanetary Disks

, 2018
The carbon and oxygen content of the solids in protoplanetary disks plays an important role in defining the composition of giant planet atmospheres. I will discuss what we know about the distribution of carbonaceous material in the solar system and discuss potential processes influencing its radial distribution. I will also present modeling results for

The MATISSE view of the inner region of the RY Tau protoplanetary disk★

Astronomy & Astrophysics
Context. The physical conditions and processes taking place in the innermost regions of protoplanetary disks are essential for planet formation and general disk evolution.

Gravitational Instability in Protoplanetary Disk with Cooling: 2D Global Analysis

The Astrophysical Journal
Self-gravity is important in protoplanetary disks for planet formation through gravitational instability (GI). We study the cooling effect on GI in a thin two-dimensional protoplanetary disk.

The Effect of Stellar Evolution on Dispersal of Protoplanetary Disks: Disk Fraction in Star-forming Regions

The Astrophysical Journal
We study the effect of stellar evolution on the dispersal of protoplanetary disks by performing one-dimensional simulations of long-term disk evolution.

The Origin of Episodic Accretion Bursts in the Early Stages of Star Formation

, 2005
We study numerically the evolution of rotating cloud cores, from the collapse of a magnetically supercritical core to the formation of a protostar and the development of a protostellar disk during the main accretion phase.
