Description
The short period cepheid HD 94033 was discovered in a photometric survey of early-type stars with high proper motion. It has a period of 85 min 42 s and a visual amplitude of 0.8 mag, from 9.465 to 10.26. It is a high velocity star (Vsub(r) = + 267 km/s), moving around the centre of the Galaxy in a highly eccentric and retrograde orbit. It is deficient in metals by a factor of 30 relative to the Sun. It is the first known short period cepheid which clearly belongs to Population II. (author)
