Radial and Vertical Constraints on the Icy Origin of H2CO in the HD 163296 Protoplanetary Disk

The Astrophysical Journal
H _2 CO is a small organic molecule widely detected in protoplanetary disks. As a precursor to grain-surface formation of CH _3 OH, H _2 CO is considered an important precursor of O-bearing organic molecules that are locked in ices.

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.

Planet Formation Regulated by Galactic-scale Interstellar Turbulence

The Astrophysical Journal Letters
Planet formation occurs over a few Myr within protoplanetary disks of dust and gas, which are often assumed to evolve in isolation. However, extended gaseous structures have been uncovered around many protoplanetary disks, suggestive of late-stage infall

Debris Disks: Probing Planet Formation

, 2018
Debris disks are the dust disks found around ~20% of nearby main sequence stars in far-IR surveys. They can be considered as descendants of protoplanetary disks or components of planetary systems, providing valuable information on circumstellar disk ...

The Short Circuit Instability in Protoplanetary Disks: Processing high temperature minerals

EPJ Web of Conferences, 2013
We introduce a magneto-hydrodynamic instability which occurs, among other locations, in the inner, hot regions of protoplanetary disks, and which alters the way in which resistive dissipation of magnetic energy into heat proceeds.
