The idea of having a meeting came to the Editors when working on
several aspects of galactic Be and B[e] stars. They found that a
general summary of the properties of B[e] stars was missing, so
that the organiza tion of a first meeting on these objects appeared
as very useful. B[e] stars have hydrogen line emission and
forbidden [Fe 11] and [0 I] emission lines in their spectra; they
are also characterized by a strong IR excess due to circumstellar
dust. Having a large amount of extinction in the UV and the visual
they have been less frequently observed than other emission line
objects. Although about one hundred galactic objects have been
classified as B[e], only fif teen or so have been studied in some
detail. Besides this, the evolutionary status of these objects is
rat her controversial, are they pre-main sequence or stars on the
way to become nUclei of planetary nebulae? Other difficult problems
appear when considering the relations of these stars with other
similar groups, like Herbig AeBe stars, Be, luminous blue variables
and the superluminous B[e] stars observed in the Magellanic Clouds.
The conference seems timely since large surveys like DENIS and
2Mass, plus new space and new instruments for the micron,
millimeter and cen timeter wavelength region will result in the
discovery of more stars of this group.
