CCD photometry of luminous stars in M33
Listed in IVOA Registry (Virtual Observatory)
The M33 galaxy is a nearby, relatively metal-poor, late-type spiral.
Description
Its proximity and almost face-on inclination means that it projects over a large area on the sky, making it an ideal candidate for wide-field CCD mosaic imaging. Photometry was obtained for more than 106 stars covering a 74'x56' field centered on M33.
Main-sequence, supergiant branch, red giant branch, and asymptotic giant branch (AGB) populations are identified and classified based on broadband V and I photometry. Narrowband filters are used to measure spectral features allowing, the AGB population to be further divided into C and M star types. The galactic structure of M33 is examined using star counts, color-color, and color-magnitude-selected stellar populations.

We use the C to M star ratio to investigate the metallicity gradient in the disk of M33.
