KeywordBl Lac Objects - Short Time-scale Variation - Relativistic Beaming Evidences
AbstractCCD image photometry data for 12 BL Lac objects have been obtained during 17 months. Light curves and photometric data are presented and discussed. The results suggest that a large-amplitude variation (Delta m = 0.45 mag or greater) on a short time scale (from a few hundred seconds to several hours) is a relatively rare phenomenon. Five of 12 BL Lac objects are variable on these time scales. Evidence for relativistic beaming in 5 BL Lac objects is discussed.
