The light curves of the short-period variable stars in the Carina dwarf Spheroidal galaxy
Received 16 November 1998 / Accepted 15 December 1998
The light curves of the high-amplitude, short-period variable stars discovered by Mateo et al. (1998) in the Carina dwarf Spheroidal Galaxy were re-analyzed to refine their properties and compare them with those of galactic stars. In spite of a different pulsation mode established by means of different PLM relationships, the Fourier parameters did not reveal a separation between the two groups; however, they are slightly different from those of galactic stars. The possibility that some of these stars are double-mode pulsators is suggested.
