| Popis: | We have obtained high-time-resolution CCD photometry of four classical T Tauri stars, and have conducted a search for rapid photometric variability with these data. Any real variations on time-scales of tens of minutes to hours are shown to be typically at most of order 0.01 mag for all four variables. The lack of flickering on short time-scales is used to place constraints on the lumpiness of the assumed accretion flow in magnetically funnelled accretion models. |
