A check on EU Tauri.
Abstract
New uvby beta RI photometry has been obtained to check the suggestion of Gieren and Matthews (1987) that the two-day classical Cepheid EU Tau had changed its period slightly and also showed a secondary period half the primary period. The present photometry does not support this suggestion. The earlier period is confirmed and improved, and there is no evidence of a secondary period. An improved color excess is derived, and this, when compared to values from a period-color relation, supports the view that EU Tau is an overtone pulsator.
