Stars with the B[e] phenomenon seen by long baseline interferometry
Marcelo Borges Fernandes (Observatorio Nacional, Rio de Janeiro, Brazil)
Thanks to the high spatial resolution provided by long baseline
interferometry, it is possible to understand the complex circumstellar
geometry around stars with the B[e] phenomenon. These stars are
composed by objects in different evolutionary stages, like high- and
low-mass evolved stars, intermediate-mass pre-main sequence stars and
symbiotic objects. However, up to now more than 50% of the confirmed
B[e] stars are not well classified, being called unclassified B[e]
stars. From instruments like AMBER and MIDI (VLTI/ESO), we have
identified the presence of gaseous and dusty circumstellar disks,
which have provided us some links related to the nature of these
objects. Thus, in this talk, I will show our results for a sample of
galactic stars with the B[e] phenomenon seen by interferometric eyes.
