3. The consolidated catalogue of tex2html_wrap_inline1992Bootis stars

 

Our catalogue, presented in Table1 (click here), consists of tex2html_wrap_inline1996Bootis stars for which classification spectra were available to us or have been observed by us, and/or for which a membership to this group is confirmed by an abundance analysis.

Candidates for this catalogue were taken primarily from Renson et al. (1990) and Gray & Corbally (1993). A critical assessment of the references was performed with SIMBAD and we could include 40 stars out of the 101 entries in Renson et al. (1990). We excluded those stars classified by Gray & Garrison (1987, 1989a,b) as non-tex2html_wrap_inline2422Bootis stars. For more details see Sect.4 (click here).
Unfortunately, there are still some measurements for tex2html_wrap_inline2424Bootis stars missing in our catalogue, especially in the ultraviolet. Nevertheless, we tried to extract those properties which are common to all catalogue stars and which seem to be significant for the tex2html_wrap_inline2426Bootis phenomenon. But still, there remains a chance of confusion with somehow phenomenologically related stars, like Be, He-weak and Horizontal Branch stars. The ultimate membership criterium would result from a spectroscopic analysis concerning abundances, tex2html_wrap_inline2428 and tex2html_wrap_inline2430, but which is time consuming. The present catalogue can provide a selection of high probability tex2html_wrap_inline2432Bootis stars for such an investigation. In conclusion, for accepting a candidate for our catalogue we used the following partially redundant criteria, of which all of them have to be fulfilled by a member, provided that the necessary observations were available:
