Intra-Day Variability and the Interstellar Medium Towards 0917+624
arXiv:astro-ph/0102194 · doi:10.1051/0004-6361:20010299
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.
