Abstract:
The process of star formation is one of the most fascinating processes in the astronomy and astrophysics. The effect of radiative heat-loss function and finite ion Larmor radius (FLR) corrections on thermal instability of infinite homogeneous viscous plasma has been investigated incorporating the effects of thermal conductivity, finite electrical resistivity and permeability for star formation. A general dispersion relation is derived using the normal mode analysis method with the help of relevant linearized perturbation equations of the problem. The wave propagation along and perpendicular to the direction of magnetic field has been discussed. Stability of the medium is discussed by applying Routh Hurwitz’s criterion. We find that the presence of FLR corrections, radiative heat-loss function and thermal conductivity modifies the fundamental criterion of thermal instability. Numerical calculations have been performed to show the effect of various parameters on the growth rate of the thermal instability. From the curves we find that heat-loss function and FLR corrections have stabilizing effect on the growth rate of thermal instability. Our results are applicable in understanding the star formation in interstellar medium.

Abstract:
The corona heating problem in solar physics relates to the question of why the temperature of the Sun's corona is millions of Kelvin higher than that of the surface. The author proposed in his paper that cosmic background radiation might be due to Cherenkov radiation from superluminal particle pairs created in a ZPF field of the vacuum. By using this theory, it can be shown that that the corona heating problem can be explained by Cherenkov radiation from superluminal particles created from the ZPF field in the hot plasma of the Sun.
