Beginning of ReadMe : J/A+A/349/619 UBVRI light curves of AA Tau in 1995 (Bouvier+, 1999) ================================================================================ Magnetospheric accretion onto the T Tauri star AA Tauri. I. Constraints from multisite spectrophotometric monitoring. Bouvier J., Chelli A., Allain S., Carrasco L., Costero R., Cruz-gonzalez I., Dougados C., Fernandez M., Martin E.L., Menard F., Mennessier C., Mujica R., Recillas E., Salas L., Schmidt G., Wichmann R. <Astron. Astrophys., 349, 619-635 (1999)> =1999A&A...349..619B ================================================================================ ADC_Keywords: Stars, pre-main sequence ; Photometry, UBVRI Keywords: accretion, accretion disks - stars: circumstellar matter - stars: magnetic fields - stars: pre-main sequence - stars: pulsars: general - stars: individual: AA Tau 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. Description: 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.
