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.

The cometary composition of a protoplanetary disk as revealed by complex cyanides

, 2015
Observations of comets and asteroids show that the Solar Nebula that spawned our planetary system was rich in water and organic molecules. Bombardment brought these organics to the young Earth's surface, seeding its early chemistry.

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

Disk Chemistry*

EPJ Web of Conferences, 2015
The chemical species in protoplanetary disks react with each other. The chemical species control part of the thermal balance in those disks. How the chemistry proceeds in the varied conditions encountered in disks relies on detailed microscopic ...

Secret of Longevity: Protoplanetary Disks as a Source of Gas in Debris Disks

The Astrophysical Journal
While protoplanetary disks (PPDs) are generally thought to disperse within several million years, recent observations have revealed gas in their older counterparts, debris disks.
