Rapid Flux Variations in Compact Radio Sources——A Shell Model

Qian Shanjie Zhao Renyang(Beijing Observatory, Academia Sinica)  
In this paper we discuss the flux variations of a shell whose expansion and bulk-motion are both at relativistic speeds. It is shown that superluminal flux variations can be produced even if the Lorentz factors of expansion and bulk-motion take moderate values (2-3), and that this kind of shell-model suggested here could be significant for interpreting very rapid flux variations at centimeter wavelengths (time scale of 1-10 days) in some radio variable sources.
