Abstract

The VLTI is a breakthrough for its capabilities to hunt and study asymmetrical circumstillar environments encountered in many targets experiencing large mass-loss rate. These environements provide important information on the perturbations of the wind carrying the mass and momentum lost by the evolved source. These perturbations are often due to companions, the short or long term interactions of the dying star with a companion encompassing a large diversity of situations, including giant planets. The VLTI is also well-suited to investigate the spatial and spectral developments of transient, explosive phenomena like Novae and some recent results on that subject will be presented.
