Massive Protostellar Disks as a Hot Laboratory of Silicate Grain Evolution
The Astrophysical Journal, 2023 Typical accretion disks around massive protostars are hot enough for water ice to sublimate. We here propose to utilize the massive protostellar disks for investigating the collisional evolution of silicate grains with no ice mantle, which is an ...

Thermodynamics of the dead-zone inner edge in protoplanetary disks [PDF]
, 2014 International audienceContext. In protoplanetary disks, the inner boundary between the turbulent and laminar regions could be a promising site for planet formation, thanks to the trapping of solids at the boundary itself or in vortices generated by the ...

Scattered Radiation of Protoplanetary Disks
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

The Determination of Protoplanetary Disk Masses [PDF]
, 2017 In this article we review the methods used to determine the gas and dust masses of protoplanetary disks, with an emphasis on the lesser characterized total gas mass. Our review encompasses all the indirect tracers and the methodology that is be used to isolate the hidden H2 via dust, CO, and HD emission.

Ionization and heating by X-rays and cosmic rays*
EPJ Web of Conferences, 2015 High-energy radiation from the central T Tauri and protostars plays an important role in shaping protoplanetary disks and influences their evolution. Such radiation, in particular X-rays and extreme-ultraviolet (EUV) radiation, is predominantly generated

Evolution of PAHs in Protoplanetary Disks [PDF]
EAS Publications Series, 2011 Depending on whom you ask, PAHs are either the smallest dust particles or the largest gas-phase molecules in space. Whether referred to as gas or dust, these PAHs can contain up to 20% of the total cosmic carbon abundance and as such also play an important role in the carbon chemistry of protoplanetary disks.

Consistent dust and gas models for protoplanetary disks [PDF]
Astronomy & Astrophysics, 2019 Context. Consistent modeling of protoplanetary disks requires the simultaneous solution of both continuum and line radiative transfer, heating and cooling balance between dust and gas and, of course, chemistry. Such models depend on panchromatic observations that can provide a complete description of the physical and chemical properties and energy ...
