Interstellar scintillation and fast radio variations in BLO 0716 + 71
Abstract
The observed rapid radio variations in BLO 0716 +71 can be interpreted in terms of interstellar scintillation, but it requires the source to contain a compact component with angular radius less than ∼ 0.1 - 0.05 mas and the scattering medium to be located nearer than ∼ 0.4kpc. The change from a 'fast mode' of variation to a 'slow mode' possibly means a change in the state of motion of the compact component. The correlation between the radio and optical variations remains a serious difficulty in this interpretation.
