Breathing Life Into Dead-Zones

EPJ Web of Conferences, 2013
The terrestrial planet formation regions of protoplanetary disks are generally sufficiently cold to be con- sidered non-magnetized and, consequently, dynamically inactive.

The Formation and Dynamics of Super-Earth Planets

, 2013
Super-Earths, objects slightly larger than Earth and slightly smaller than Uranus, have found a special place in exoplanetary science. As a new class of planetary bodies, these objects have challenged models of planet formation at both ends of the ...

On Kinematic Measurements of Self-gravity in Protoplanetary Disks

The Astrophysical Journal
Using controlled injection and recovery experiments, we devised an analysis prescription to assess the quality of dynamical measurements of protoplanetary disk gas masses based on resolved (CO) spectral line data, given observational limitations ...

The Carbon Isotopic Ratio and Planet Formation

The Astrophysical Journal
We present the first detection of ^13 CCH in a protoplanetary disk (TW Hya). Using observations of C _2 H, we measure CCH/ ^13 CCH = 65 ± 20 gas with a CO isotopic ratio of ^12 CO/ ^13 CO = 21 ± 5.

Observations of inhomogeneities in protoplanetary disks

EPJ Web of Conferences, 2013
In this review I will give a brief overview of the latest observational constraints on the structure and dynamics of protoplanetary disks, with a particular emphasis on the topic of the conference: vortices.

Formation and evolution of the protoplanetary disk [PDF]

A disk formation model during collapse of the protosolar nebula, yielding a low-mass protoplanetary disk is presented. The following subject areas are covered: (1) circumstellar disks; (2) conditions for the formation of stars with disks; (3) early ...

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.
