D. Cieslinski et al., SOUTHERN AND EQUATORIAL IRREGULAR VARIABLES - II - OPTICAL SPECTROSCOPY, Astronomy & Astrophysics. Supplement series, 131(1), 1998, pp. 119-135
The results of optical spectroscopy of 169 southern and equatorial obj
ects previously known as irregular variables are presented. The target
s were selected via photoelectric UBV photometry among objects classif
ied as L, L:, I, I, IS and IS: in the General Catalogue of Variable St
ars and New Catalogue of Suspected Variable Stars. Among these objects
we have identified 8 cataclysmic variables, 8 symbiotic stars and sta
rs that belong to a variety of other classes.
