The Role of Diffusive Shock Acceleration on Nonequilibrium Ionization in Supernova Remnant Shocks II: Emitted Spectra
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
We present a grid of nonequilibrium ionization models for the X-ray spectra from supernova remnants undergoing efficient diffusive shock acceleration. The calculation follows the hydrodynamics of the ...
Diffusive Cosmic Ray Acceleration at the Galactic Centre
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/5
The diffuse TeV emission detected from the inner $\sim2^\circ$ of the Galaxy appears to be strongly correlated with the distribution of molecular gas along the Galactic ridge. Although it is not yet e...
Residence Times of Particles in Diffusive Protoplanetary Disk Environments I. Vertical Motions
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/27
The chemical and physical evolution of primitive materials in protoplanetary disks are determined by the types of environments they are exposed to and their residence times within each environment.
