By Anne Marie Hubert,Carlos Jaschek

the belief of getting a gathering got here to the Editors whilst engaged on a number of points of galactic Be and B[e] stars. they discovered normal precis of the homes of B[e] stars used to be lacking, in order that the organiza­ tion of a primary assembly on those gadgets seemed as very valuable. B[e] stars have hydrogen line emission and forbidden [Fe eleven] and [0 I] emission strains of their spectra; also they are characterised by means of a robust IR extra because of circumstellar dirt. Having a large number of extinction within the UV and the visible they've been much less usually saw than different emission line items. even supposing approximately 100 galactic items were categorized as B[e], basically fif­ youngster or so were studied in a few aspect. along with this, the evolutionary prestige of those gadgets is rat her arguable, are they pre-main series or stars to be able to turn into nUclei of planetary nebulae? different tough difficulties look while contemplating the family members of those stars with different related teams, like Herbig AeBe stars, Be, luminous blue variables and the superluminous B[e] stars saw within the Magellanic Clouds. The convention turns out well timed in view that huge surveys like DENIS and 2Mass, plus new area and new tools for the micron, millimeter and cen­ timeter wavelength zone will lead to the invention of extra stars of this group.
