COMMISSION 27 OF THE I. A. U. INFORMATION BULLETIN ON VARIABLE STARS Number 1958 Konkoly Observatory Budapest 1981 April 21 HU ISSN 0374-0676 VARIABLE STARS IN THE LSS CATALOGUE Among the 5132 objects contained in Stephenson and Sanduleak's (1971) catalogue of "Luminous Stars in the Southern Milky Way" are a considerable number of variable stars. Most of those known at the time were noted as such in the catalogue but, of course, many additional variables have been found since its publication. Table I lists those stars of the catalogue that are now, to the writer's knowledge, either named variables or contained in the two catalogues of stars suspected of variability. The literature search included the 3rd edition of the GCVS, its three supplements, and the 62nd through 65th variable-star naming lists (I.A.U. Var. Star Bull. Nos. 1248, 1414, 1581,and 1921). A few additional as-yet unnamed variables are also known but are not included. The objective-prism spectral classifications of the LSS catalogue are generally expressed in terms of the OB natural group nomenclature, as is also true for the similar Case-Hamburg northern-hemisphere luminous star survey. Their significance can be judged by reference to Fig. 1, prepared by N. Sanduleak, of the writer's (1972) paper. In many cases actual MK types are also available in the literature, but this is not generally true for the fainter stars. The U Geminorum star CZ Orionis (LSS 30, OB^-) and the large-range 8.8-day eclipsing binary AI Sagittarii (LSS 4851, OB), among others, are especially notable in this regard. It is also worthy of mention that the LSS catalogue gives accurate coordinates and useful charts for all of its entries. TABLE I VARIABLE STARS IN THE LSS CATALOGUE LSS No. Spectrum Name or Susp.
