Finding beat Cepheids in M33 and their use in measuring the metallicity gradient

The period ratio between the two different pulsation modes of beat Cepheids is directly affected by the metallicity of the star. Our aim is to find all of the beat Cepheids in M33 and determine their metallicities hence allowing us to derive the metallicity gradient. To achieve this we have M33 data...
