... Having quite low efficiency at this pilot stage it is natural to try to improve the selection criteria. The analysis of all accumulated data discussed here, shows that in order to improve the selection of BCGs the following additional criteria and selection procedures should be applied to the preselected lists of candidates: . ... The results of follow-up spectroscopy have shown that even part of the prominent first priority candidates turned out non-emission objects. ...

... Nonadiabatic linear pulsation models have been calculated for low-mass stars with effective temperatures between 16,000 and 35,000 K, and with surface gravities in the range 3 0.3, although the position of the red edge is sensitive to X. We have found that non-radial pulsations are also excited in the same instability region as radial pulsations. The implications of these results for individual low-mass helium stars are discussed. ...
