Abstract
The early evolution of Sun-like stars may be interspersed by energetic FU Orionis (FUor) type accretion outbursts. We analysed eight years o photometric and spectroscopic variability of V582 Aur, a bona fide FUor in outburst. While the accretion rate derived from near-infrare measurements was constant, radical brightness changes occurred due t dust clumps crossing the line of sight. The brightness minima resembl the variability patterns of the UXor phenomenon. Orbiting densit sight may explain these observations. Our message is that during FUo outbursts the inner disk is a dynamically active place, affecting th initial conditions for planet formation
