Protoplanetary Disks as (Possibly) Viscous Disks [PDF]
, 2017 Protoplanetary disks are believed to evolve on megayear timescales in a diffusive (viscous) manner as a result of angular momentum transport driven by internal stresses. Here we use a sample of 26 protoplanetary disks resolved by ALMA with measured (dust-

Gas evolution in protoplanetary disks [PDF]
, 2009 This article summarizes a Splinter Session at the Cool Stars XV conference in St. Andrews with 3 review and 4 contributed talks. The speakers have discussed various approaches to understand the structure and evolution of the gas component in ...

Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Molecular Hydrogen Emission from Protoplanetary Disks [PDF]
, 2005 We have modeled self-consistently the density and temperature profiles of gas and dust in protoplanetary disks, taking into account irradiation from a central star.

Volatiles in Protoplanetary Disks [PDF]
, 2015 Planets are assembled from the gas, dust, and ice in the accretion disks that encircle young stars. Ices of chemical compounds with low condensation temperatures (<200 K), the so-called volatiles, dominate the solid mass reservoir from which ...

The Astrophysical JournalEccentric planets constitute a large population of the known exoplanets and may drive significant substructures in protoplanetary disks through planet–disk interactions if their eccentricities are excited early in the planet formation process.

Light Echoes of Time-resolved Flares and Application to Kepler Data
The Open Journal of AstrophysicsLight echoes of stellar flares provide an intriguing option for exploring protoplanetary disks in young stellar systems. Previous work on light echoes of circumstellar disks made use of delta-function flares for modeling.

Gas in Protoplanetary Disks [PDF]
, 2008 Gas makes up the bulk of the mass in a protoplanetary disk, but it is much more difficult to observe than the smaller dust component. The lifetime of gas in a disk has far-reaching consequences, including limiting the time available for giant planet ...

Tracing the evolution of protoplanetary disks [PDF]
, 2014 This thesis presents new insights of protoplanetary disk evolution. It focuses on the characterisation of several elements in the earliest phases of planet formation in protoplanetary disks: the connection between the SED and disk gaps (Chapters 2, 3 and

Dust Evolution in Protoplanetary Disks [PDF]
, 2014 In the core-accretion scenario for the formation of planetary rocky cores, the first step toward planet formation is the growth of dust grains into larger and larger aggregates and eventually planetesimals.
