HNC in Protoplanetary Disks [PDF]

, 2016
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.

Asymmetric Temperature Variations In Protoplanetary Disks. I. Linear Theory, Corotating Spirals, and Ring Formation

The Astrophysical Journal
Protoplanetary disks can exhibit asymmetric temperature variations due to phenomena such as shadows cast by the inner disk or localized heating by young planets. We investigate the disk features induced by these asymmetric temperature variations. We find

The Empirical and Radiative Transfer Hybrid (EaRTH) Disk Model: Merging Analyses of Protoplanetary Dust Disk Mineralogy and Structure

The Astrophysical Journal
Our understanding of how exoplanets form and evolve relies on analyses of both the mineralogy of protoplanetary disks and their detailed structures; however, these key complementary aspects of disks are usually studied separately.

Surface Energy of Insoluble Organic Matter Simulant: Evaluation Based on Adhesive Force Measured by Centrifugal and Impact Separation Methods

The Planetary Science Journal
In protoplanetary disks, organic mantle is regarded as promoting the collisional sticking of rocky dust grains. However, the surface energy, which is one of the primary factors determining collisional sticking, has not been well quantified.

Turbulence Can Persist in the Inner Regions of Weakly Ionized Planet-forming Disks

The Astrophysical Journal
Identifying the mechanisms responsible for angular momentum transport in protoplanetary disks, and the extent to which those mechanisms produce turbulence, is crucial in understanding planet formation. The bulk of a disk is weakly ionized, which leads to

Measuring the Two-dimensional Thermal Structures of Protoplanetary Disks

The Astrophysical Journal
We present a flexible, annulus-by-annulus method to constrain the 2D thermal structure of a protoplanetary disk from optically thick spectral line emission.
