“…Small amplitude waves in this approximation have been studied in [4,9,6,8] while the only solution for MHD shock waves was obtained for the case of parallel shock waves propagating along the magnetic field [10]. Conditions have also been found for the parameters in front of such waves when instabilities are generated behind the shock leading to plasma turbulence [11].…”

“…Previously, many authors have independently studied the thermal pressure anisotropy-driven waves and instabilities considering the effects of various parameters, e.g., uniform rotation, self-gravitation, heat-flux vector, viscosity, etc., due to their unavoidable role in space and astrophysical plasmas [2,20,21,[31][32][33]. Liu et al [34] have investigated the effects of pressure anisotropy on stable and unstable parallel-propagating wave modes in the plasmas.…”

The effects of finite Larmor radius (FLR) corrections and heat-flux vector are studied on the pressure anisotropy-driven firehose instability in finitely conducting solar wind plasmas described by the double-adiabatic Chew, Goldberger and Low (CGL) fluid theory. The fluid description of collisionless plasmas is governed through modified adiabatic equations due to the heat-flux vector and finite ion Larmor radius corrections. The analytical dispersion relation of the firehose instability has been derived using the normal mode analysis and discussed in the solar wind plasmas. In the transverse mode, the dispersion relation of Alfv´enic mode is modified due to electrical resistivity and FLR corrections. In the longitudinal mode, the effects of the heat-flux parameter and electrical resistivity are observed separately. The dispersion relation of the firehose mode is modified due to the combined effects of FLR corrections and electrical resistivity. The graphical illustrations show that finite electrical resistivity and ion Larmor frequency destabilize the growth rate of the firehose instability. The results are useful for analyzing the solar mission data to study the firehose instability in the solar wind plasmas.
