Abstract:We have monitored the photometric, spectroscopic and polarimetric variations of the classical T Tauri star (CTTS) AA Tau over a period of a month. The light curve consists of more than 260 measurements in each of the B and V-bands over a continuous time period of 30 days and more than 180 measurements in the R and I-bands. This provides unprecedented detail of the photometric variations of a CTTS on timescales ranging from hours to weeks. ...(more)

Astronomy and Astrophysics policies
All photometric observations were obtained with CCD devices using UBVRI filters or a subset thereof. The Journal of Observations is given in Table 1. Near-IR measurements (Table 2) were obtained on AA Tau in the JHK filters over 6 nights encompassing part of the first fading episode and the return of the system to the bright state.
