Intra-Day Variability and the Interstellar Medium Towards 0917+624
D. L. Jauncey, J. -P. Macquart
Abstract
The intra-day variable source 0917+624 displays annual changes in its timescale of variability. This is explained in terms of a scintillation model in which changes in the variability timescale are due to changes in the relative velocity of the scintillation pattern as the Earth orbits the sun.
