Dr. Istvan Ballai's main research interest is in linear and nonlinear MHD waves occurring in solar and interplanetary plasmas. Waves can carry energy and momentum; when transferred to inhomogeneous plasmas they can heat or accelerate the plasma therefore MHD waves may play an important role in explaining the observed high temperatures in the solar corona. Waves can transport information about the environment in which they propagate, so they serve as a perfect tool for plasma diagnostics. We use local and global coronal waves to find average values for magnetic field and transport coefficients in the solar corona.
