HD 304373, the second case of 1O/2O double-mode Cepheid in the Galaxy.

BELTRAME M. and PORETTI E.

Abstract (from CDS):

We report on the discovery of the second case of a galactic Cepheid, ASAS 112843-5925.7=HD 304373, pulsating in the the first (1O) and second (2O) radial overtones. The ratio between the periods (0.8058), the short value of the 1O period (0.922405 d) and the shape of the 1O light curve makes HD 304373 very similar to the 1O/2O Cepheids in the Magellanic Clouds. The implications of a so close similarity between a galactic 1O/2O pulsator and LMC ones are discussed in terms of importance of the metallicity effects.
