Observation of Impulsive Acoustic Events and the Excitation of Solar Oscillations.
Abstract
A new set of observations has been made of the intensity and Doppler shift in the 543.4nm Fel line consisting of 356 spatial points in a row 1024 arc seconds long. For these observations new data acquisition software and new data reduction routines were developed. Wave number versus frequency diagrams have been obtained at several altitudes in the photosphere. It has been shown that the changes in the sun's internal rotation over the sun's activity cycle occurs just above the base of the convection zone. A seismic method has been developed to directly determine the sun's internal angular momentum and seismic limits have been placed on the sun's internal magnetic field.
