Rapid X-ray variability in the Seyfert galaxy NGC 4593.
Abstract
The results of s series of Exosat and Einstein observations of the Seyfert galaxy NGC 4593 are presented. Rapid X-ray variability was found in five observations out of seven. The observed variability timescale is a strong function of the mean source intensity, the source varying more slowly when its luminosity is higher.
