  • Oscillatory motions in intense flux tubes 
    Hasan, S. S (Royal Astronomical Society, 1986-03)
    The intricate nature of oscillatory motions in intene flux tubes is examined and states in which the ratio of gas to magnetic pressure (Beta) is constant are considered. Results are presented for both polytropic and real ...
