Instability of a diffusive shock wave in a plasma with cosmic rays
Abstract
An instability criterion is proposed for magnetoacoustic waves in a plasma in front of a cosmic-ray-modified shock, i.e., a shock affected by cosmic-ray pressure. The results are important for the assessment of the effect of cosmic rays on plasma dynamics in interstellar space.
