In the polytropic zone of the solar wind, we have used the generalized polytrope pressure laws to investigate the dissipation of hydromagnetic waves and pressure anisotropy driven fluid instabilities in magnetized viscous plasmas including finite Larmor radius (FLR) corrections and non-ideal magnetohydrodynamic (MHD) effects. The modified dispersion properties have been analyzed in the MHD and Chew-Goldberger-Low (CGL) limits for typical conditions of solar wind and corona. The theoretical results are found to be in good agr ...

MHD-scale anisotropy in solar wind turbulence near the Sun using Parker solar probe data Recent Parker Solar Probe (PSP) observations have shown the presence of sudden reversals in the radial magnetic field, known as switchbacks. Applying a method based on wavelet analysis, here we study the nature of power and spectral-index anisotropies in switchback and non-switchback intervals using PSP data. While a similar spectral-index anisotropy, consistent with critical balance, is found in the switchback and non-switchback intervals, power anisotropy is more enhanced in the non- switchback samples. This result may be ...
