The effect of metallicity on Cepheid magnitudes and the distance to M33
We present the results from a multi-epoch survey of two regions of M33 using the 3.5-m Wisconsin-Indiana-Yale-NOAO (WIYN) telescope. The inner field is located close to the centre of the galaxy, with the outer region situated about 5.1 kpc away in the southern spiral arm, allowing us to sample a large metallicity range. We have data for 167 fundamental mode Cepheids in the two regions. The reddening-free Wesenheit magnitude Wvi period-luminosity (PL) relations were used to establish the...[Show more]
