On the Dynamics of Protoplanetary Disks [PDF]
, 2018 Protoplanetary disks are disks of gas and dust orbiting young stars which form planetary systems. This thesis is devoted to understanding how gravitational interactions in different astrophysical situations effect the structure and dynamical evolution ...

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 ...

Photoprocesses in protoplanetary disks [PDF]
Faraday Discussions, 2006 Circumstellar disks are exposed to intense ultraviolet radiation from the young star. In the inner disks, the UV radiation can be enhanced by more than seven orders of magnitude compared with the average interstellar field, resulting in a physical and chemical structure that resembles that of a dense photon-dominated region (PDR). This intense UV field

HNC IN PROTOPLANETARY DISKS [PDF]
The Astrophysical Journal, 2015 The distributions and abundances of small organics in protoplanetary disks are potentially powerful probes of disk physics and chemistry. HNC is a common probe of dense interstellar regions and the target of this study. We use the Submillimeter Array (SMA) to observe HNC 3--2 towards the protoplanetary disks around the T Tauri star TW Hya and the ...

The Inner Regions of Protoplanetary Disks [PDF]
Annual Review of Astronomy and Astrophysics, 2010 To understand how planetary systems form in the dusty disks around pre-main-sequence stars, a detailed knowledge of the structure and evolution of these disks is required. Although this is reasonably well understood for the regions of the disk beyond about 1 AU, the structure of these disks inward of 1 AU remains a puzzle. This is partly because it is

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 ...
