Název v původním jazyce

Nonlinear competition between the whistler and Alfven firehoses. Journal of Geophysical Research, 106, 13,215, 2001.

Popis výsledku v původním jazyce

We examine a competition between the whistler and Alfven fire hoses driven by bi-Maxwellian protons with T_par greater than T_perp, where T_par and T_perp are proton temperatures, parallel and perpendicular to the background magnetic field, respectively.We extend the work of Hellinger and Matsumoto [2000] using a two-dimensional hybrid simulation that includes both the instabilities. In the simulation the whistler fire hose initially dominates and saturates in a quasi-linear manner. The Alfven fire hose is not strongly affected by the presence of the whistler fire hose and grows even when the former is saturated. However, as the Alfven fire hose grows and saturates via a conversion to Alfven waves that heat the protons, the waves driven by the whistler fire hose get strongly damped and disappear. The Alfven waves damp as well, so that at the end of the simulation the wave activity is low. The strong decay of the generated waves translates to an important decrease of the proton tempera
