Abstract
In this paper we present the results of a long campaign of coordinated (sometimes simultaneous) multifrequency observations, from X-ray to radio wavelengths of the extreme T Tauri star RU Lupi. The large amount of data obtained can be useful to understanding the physics governing the intriguing behaviour of this pre-main-sequence star. In particular, from the whole set of data, a model with a protoplanetary accretion disk around a moderately magnetic star seems to be the most promising picture for this source.
