Mass Distribution and Planet Formation in the Solar Nebula
The surface density profile Σ(r) of the solar nebula protoplanetary disk is a fundamental input to all models of disk processes and evolution. Traditionally it is estimated by spreading out theExpand

Interaction of Supernova Ejecta with Nearby Protoplanetary Disks
The early solar system contained short-lived radionuclides such as 60Fe (t1/2 = 1.5 Myr) whose most likely source was a nearby supernova. Previous models of solar system formation considered aExpand

Near-Infrared Spectroscopy of Charon: Possible Evidence for Cryovolcanism on Kuiper Belt Objects
We present the first reported adaptive optics spectra of Charon in the H and K bands, which examine the anti-Pluto and sub-Pluto hemispheres. The ice temperature is estimated at 40-50 K, based on theExpand

A model of the thermal processing of particles in solar nebula shocks: Application to the cooling rates of chondrules
We present a model for the thermal processing of particles in shock waves typical of the solar nebula. This shock model improves on existing models in that the dissociation and recombination of H2Expand

The Generation of Lightning in the Solar Nebula
Abstract The process that melted and formed the chondrules, millimeter-sized glassy beads within meteorites, has not been conclusively identified. Origin by lightning in the solar nebula isExpand

The Effect of Jupiter's Formation on the Distribution of Refractory Elements and Inclusions in Meteorites
We present a comprehensive evolutionary model of the Sun's protoplanetary disk. The model predicts from first principles the gas densities and temperatures, and abundances of calcium-rich,Expand

The Magnetic Decoupling Stage of Star Formation
We present the results of the first numerical calculations to model magnetic decoupling in a collapsing molecular cloud core. Magnetic decoupling is the stage during which the motion of the neutralsExpand

The importance of experiments: Constraints on chondrule formation models
Abstract— We review a number of constraints that have been placed on the formation of chondrules and show how these can be used to test chondrule formation models. Four models in particular areExpand

Thermal evolution of Kuiper belt objects, with implications for cryovolcanism
Abstract We investigate the internal thermal evolution of Kuiper belt objects (KBOs), small (radii 2500 kg m − 3 ) bodies orbiting beyond Neptune, focusing on Pluto's moon Charon in particular. OurExpand

Thermal histories of chondrules in solar nebula shocks, including the effect of molecular line cooling
Chondrules are important early Solar System materials that can provide a wealth of information on conditions in the solar nebula, if their formation mechanism can be understood. The theory mostExpand
