VR light curves of AA Tau in 2007-2013
Listed in IVOA Registry (Virtual Observatory)
AA Tau has been monitored for more than 20 years since 1987, exhibiting a nearly constant brightness level of V=12.5mag.
Description
We report here that in 2011 it suddenly faded away, becoming 2 magnitudes fainter in the V-band, and has remained in this deep state since then. We investigate the origin of the sudden dimming of the AA Tau system.
We report new optical and near-IR photometry and spectroscopy obtained during the fading event.
