Mass Distribution and Planet Formation in the Solar Nebula
- S. Desch
- Physics
- 10 December 2007
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 the… Expand
Interaction of Supernova Ejecta with Nearby Protoplanetary Disks
- N. Ouellette, S. Desch, J. J. Hester
- Physics
- 12 April 2007
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 a… Expand
Near-Infrared Spectroscopy of Charon: Possible Evidence for Cryovolcanism on Kuiper Belt Objects
- J. C. Cook, S. Desch, T. Roush, C. Trujillo, T. Geballe
- Geology, Physics
- 1 September 2006
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 the… Expand
A model of the thermal processing of particles in solar nebula shocks: Application to the cooling rates of chondrules
- S. Desch, H. C. Connolly
- Physics
- 1 February 2002
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 H2… Expand
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 is… Expand
The Effect of Jupiter's Formation on the Distribution of Refractory Elements and Inclusions in Meteorites
- S. Desch, A. Kalyaan, C. Alexander
- Physics
- 10 October 2017
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
- S. Desch, T. C. Mouschovias
- Physics
- 20 March 2001
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 neutrals… Expand
The importance of experiments: Constraints on chondrule formation models
- S. Desch, M. Morris, H. C. Connolly, A. Boss
- Geology
- 1 July 2010
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 are… Expand
Thermal evolution of Kuiper belt objects, with implications for cryovolcanism
- S. Desch, J. C. Cook, T. Doggett, S. Porter
- Geology
- 1 August 2009
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. Our… Expand
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 most… Expand
