| Description
| - Pomalá expanze, modelovaná dvoudimenzionální hybridní simulací v expandující krabici, generuje protonovou teplotní anisotropii. Tato anizotropie vede nejdříve ke destabilizaci podélné hadicové nestability, která interaguje především s minoritními supraalfvénovskými protony, zatímco vývoj protonového jádra je determinovaný expanzí, následkem čehož je protonová anizotropie jenom lehce redukována. Expandující systém nakonec destabilizuje šikmou hadicovou nestabilitu, která silně rozptyluje protony, čímž silně omezuje protonovou teplotní anisotropii, takže naruší vývoj podélné hadicové nestability. Tyto výsledky vedou k závěru, že obě hadicové nestability obmezují protonovou teplotní anizotropii ve slunečním větru, přičemž šíkmá hadicová nestabilita určuje její krajní mez. Tyto výsledky také dávají možné vysvětlení zjevného rozporu mezi pozorováními a lineární předpovědí. (cs)
- A slow plasma expansion, modelled by a two-dimensional hybrid expanding box simulation, leads to a generation of proton temperature anisotropy. The anisotropy leads first to destabilization of the dominant parallel fire hose which interacts mainly with minor supra-Alfvénic protons whereas the evolution of core protons is determined by the expansion. Consequently, the effective anisotropy is only slightly reduced and the system eventually becomes unstable with respect to the oblique fire hose instability. The oblique fire hose strongly scatters the protons and removes the anisotropy disrupting the parallel fire hose. It is concluded that both parallel and oblique proton fire hose instabilities constrain the proton temperature anisotropy in the expanding solar wind with the latter one constituting a final frontier for the anisotropy. These results give a possible explanation of some apparent discrepancies between observations and linear predictions.
