  • Classification of Magnetoatmospheric Modes in Sunspot Umbrae 
    Hasan, S. S; Sobouti, Y (International Astronomical Union, 1990)
    We examine the wave modes in a sunspot umbra. Assuming stratification, based on a model atmosphere in a sunspot, the normal mode spectrum is determined. The modes are classified using a scheme based on a Helmholtz decomposition ...
  • Mode classification and wave propagation in a magnetically structured medium 
    Hasan, S. S; Sobouti, Y (Blackwell, 1987-09)
    The authors examine the structure of motions that can occur in a vertical magnetic flux tube with a rectangular cross-section. A polytropic stratification is assumed in the vertical direction. The authors use a gauged ...
