    Rotational splitting of low L solar p-mode
    Rotational splitting measurements of less than 5 p-modes are calculated using different sources of data. For l=1, data obtained from years 1981 to 1985 is used...

    Solar core rotation
    Data from solar line of sight velocity measurements are presented to demonstrate the existence of a synodic signal with a 6.5 m/sec amplitude. Recordings of...

    Solar cycle induced variations of the low L solar acoustic spectrum
    Doppler velocity data are used to study solar cycle variation of the frequencies of solar acoustic oscillations from 1977 to 1988. The results show a clear...
