UBVRI light curves of AA Tau in 1999
Listed in IVOA Registry (Virtual Observatory)
We report the results of a synoptic study of the photometric and spectroscopic variability of the classical T Tauri star AA Tau on timescales ranging from a few hours to several weeks.
Description
The AA Tau light curve had been previously shown to vary with a 8.2d period, exhibiting a roughly constant brightness level, interrupted by quasi-cyclic fading episodes, which we interpreted as recurrent eclipses of the central star by the warped inner edge of its accretion disk (Bouvier et al. 1999, Cat. <J/A+A/349/619>).
Our observations show the system is dynamic and presents non-stationary variability both in the photometry and spectroscopy.
