Volatiles in protoplanetary disks [PDF]
, 2014 Volatiles are compounds with low sublimation temperatures, and they make up most of the condensible mass in typical planet-forming environments. They consist of relatively small, often hydrogenated, molecules based on the abundant elements carbon ...

Dust properties of protoplanetary disks in the Taurus-Auriga star forming region from millimeter wavelengths [PDF]
, 2010 We present the most sensitive 3 mm-survey to date of protoplanetary disks carried in the Taurus-Auriga star forming region (average rms of about 0.3 mJy), using the IRAM PdBI.

The evolution of the water distribution in a viscous protoplanetary disk [PDF]
, 2005 (Abridged) Astronomical observations have shown that protoplanetary disks are dynamic objects through which mass is transported and accreted by the central star.

Scattered Radiation of Protoplanetary Disks [PDF]
Universe, 2022 Scattered radiation of circumstellar (CS) dust plays an important role in the physics of young stars. Its observational manifestations are various but more often they are connected with the appearance of intrinsic polarization in young stars and their CS

Herschel evidence for disk flattening or gas depletion in transitional disks [PDF]
, 2014 Transitional disks are protoplanetary disks characterized by reduced near- and mid-infrared emission with respect to full disks. This characteristic spectral energy distribution indicates the presence of an optically thin inner cavity within the dust ...

Finding Substructures in Protostellar Disks in Ophiuchus
The Astronomical Journal, 2023 High-resolution, millimeter observations of disks at the protoplanetary stage reveal substructures such as gaps, rings, arcs, spirals, and cavities. While many protoplanetary disks host such substructures, only a few at the younger protostellar stage ...

Demographics of Protoplanetary Disks: A Simulated Population of Edge-on Systems
The Astrophysical Journal, 2023 The structure of protoplanetary disks plays an essential role in planet formation. A disk that is highly inclined, or “edge-on,” is of particular interest since its geometry provides a unique opportunity to study the disk’s vertical structure and radial ...

A numerical approach to model chemistry of complex organic molecules in a protoplanetary disk
Open Astronomy, 2022 Multiphase astrochemical modeling presents a numerical challenge especially for the simulation of objects with the wide range of physical parameters such as protoplanetary disks.

Kinematic Evidence of an Embedded Protoplanet in HD 142666 Identified by Machine Learning
The Astrophysical Journal, 2023 Observations of protoplanetary disks have shown that forming exoplanets leave characteristic imprints on the gas and dust of the disk. In the gas, these forming exoplanets cause deviations from Keplerian motion, which can be detected through molecular ...
