Abstract:
Photometric observations have been made of 36 stars classified as CST
or CST: in the General Catalogue of Variable Stars. Six of these stars
are found to vary and three others were deemed possible variables. Of
the certain variables, two (MR Her and TY Sge) are red pulsators, one
(V1585 Cyg) is a rapid irregular variable, one is apparently a short
period Cepheid-strip star (V432 Oph), one is an eclipsing binary (AQ
Boo) and one is uncertain type (V351 Cyg). The stars we have observed
as MR Her and TY Sge are the same ones which were identified on
finding charts in the discovery papers suggesting that these stars
have intervals of variability and intervals of quiescence. V432 Oph is
of special interest because our photometry indicates that it may be
either a double mode Cepheid or a peculiar long period RR Lyrae star
depending on which of a couple of possible periods turns out to be
correct.
