Accretion disks are associated with such diverse objects as planetary systems, Be stars, and spiral galaxies. However, their structure is poorly defined by existng observational data. This study was an attempt to gather specific structural information about the disks in Algol-type binary systems. In Algol-type binaries mass transfer from the secondary star forms a gaseous disk which surrounds the hotter companion. During the primary eclipse both the central star and the disk undergo a brief occulation. Conventional photographic spectroscopy cannot record the rapid spectral changes which give information on the size, velocities, and physical conditions of the disk. In this study, time-resolved spectroscopy was obtained with modern TV-type multiplexed detectors.
