The Short Circuit Instability in Protoplanetary Disks: Processing high temperature minerals
EPJ Web of Conferences, 2013 We introduce a magneto-hydrodynamic instability which occurs, among other locations, in the inner, hot regions of protoplanetary disks, and which alters the way in which resistive dissipation of magnetic energy into heat proceeds.

Oxygen Isotopic Compositions of Chondrules as Probes of Solar Protoplanetary Disk Formation
The Astrophysical JournalChondrules are thought to have formed during transient flash-heating events in dust-enriched regions of the solar protoplanetary disk. Although laboratory studies have characterized the oxygen isotopic compositions of chondritic materials, quantitative ...
