| Abstract: |
Dust formation around evolved hot stars requires special con- ditions, such as very high matter densities or hydrogen deficiency. Only a few groups of hot and luminous stars producing new dust are currently known (Wolf-Rayet stars, B[e] supergiants, and LBVs). Studying unclassified B[e] stars, we have identified another distinct group of ~20 intermediate luminosity (log L/L⊙ =2.5–5.1) hot stars with IRAS fluxes suggestive of a recent CS dust forma- tion process. Our search for optical counterparts of IRAS sources with similar colors in recently released all-sky surveys (2MASS and USNO–B1.0) resulted in finding 40 new candidates to the group. The group properties and recent observational results are discussed. |
