Damping of longitudinal magneto-acoustic oscillations in slowly varying coronal plasma
magnetohydrodynamics(MHD) - plasmas - Sun corona - waves
2010/11/15
We investigate the propagation of MHD waves in a homogenous, magnetized plasma in a weakly
stratified atmosphere, representing hot coronal loops. In most of earlier studies a time-independent equilib...
Magnetic field amplification and electron acceleration to near-energy equipartition with ions by a mildly relativistic quasi-parallel plasma protoshock
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
The prompt emissions of gamma-ray bursts are seeded by radiating ultrarelativistic electrons. Internal shocks propagating through a jet launched by a stellar implosion, are expected to amplify the mag...
