Finite-\(\beta\) effects on the radiative thermal instability in magnetized plasmas. (English) Zbl 0678.76037
Summary: The radiative thermal instability is investigated taking into account finite-\(\beta\), or electromagnetic, effects. The two-fluid model for magnetized plasmas together with the Maxwell equations are used to derive a general dispersion relation valid for compressional perturbations with frequency below the electron-cyclotron frequency. The growth rates of the radiative thermal instabilities involving fast magnetosonic flute-like and low-frequency hydromagnetic perturbations are presented.
