Abstract
Stars that present the B[e] phenomenon are known to form a heterogeneous group. This group is composed by objects in different evolutionary stages, like high- and low-mass evolved stars, intermediate-mass pre-main sequence stars and symbiotic objects. However, for more than 50% of the confirmed B[e] stars the evolutionary stage is still unknown, so that they are gathered in the group of the unclassified B[e] stars. High-angular resolution interferometry is certainly an important tool to answer questions related to the circumstellar geometry of these objects. In this work, we present the results related to seven objects, based on observations from VLTI/MIDI, VLTI/AMBER and CHARA/VEGA.
