Effect of time dependent background temperature on slow waves in viscous coronal plasma
Author(s): Anil Kumar and Nagendra Kumar
Abstract: We study the effect of varying background temperature on small amplitude oscillations interpreted in terms of slow magneto hydrodynamic waves in solar coronal structures like prominences and coronal loops. We consider two damping mechanisms radiation and viscosity to study the behavior of slow MHD waves. We solve the MHD equations numerically to examine the effects of radiation and viscosity on velocity amplitude. It is found that amplitude of perturbed velocity decreases in case of increasing background temperature, whereas the perturbed velocity amplitude increases in case of decaying background temperature.
