Nascut(a) in: 1955

Interese: solar physics, MHD waves

Detalii:
Studii analitice si numerice asupra efectelor disipative( vascozitate, conductivitate termica, rezistivitate electrica, damping radiativ) asupra propagarii si dampingului undelor MHD compresive in diferite structuri plasmatice solare.

Details:
Analytical and numerical study of the dissipative effects (isotropic and anisotropic viscosity, anisotropic thermal conduction, electrical resistivity, radiative damping) which may count for damping of linear compressional magnetohydrodynamic waves in solar structures. The theoretical results are compared with the recent observations of the wave damping in solar atmosphere.
