font style='font-size:12px;'>
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
