Analysis of the Instability Growth Rate During the Jet - Background Interaction in the Magnetic Field

Popis výsledku v původním jazyce

The two-stream instability is the common instability, which is responsible for many observed phenomena in nature, especially the interaction of the jets of various origin with the background plasma (e.g. extragalactic jet penetrating into the cosmic background). The dispersion relation without magnetic field is described by the well-known Buneman relation, but in 2011 Bohata, Bren, and Kulhanek derived the relation for the two-stream instability without the cold limit and with the general orientation ofmagnetic field. The maximum value of the imaginary part of the individual dispersion branches is very interesting from the physical point of view. It represents the instability growth rate which is responsible for the turbulence mode onset and subsequent reconnection on the ion radius scale accompanied by strong plasma thermalization. The paper presented here is focused on the instability growth rate dependence on various input parameters, such as magnitude and direction of magnetic fie
