M33 has a distance modulus of D=24.64 and AGB stars\r\nare highly luminous, allowing resolved population studies with 4 metre class telescopes. AGB stars are identified and classified in C (carbon) and M-type stars.\r\nExamining star counts and colour-magnitude selected stellar populations, the galactic\r\nstructure of M33 is examined. Further, we search for evidence of galactic interactions\r\nas seen in other nearby galaxies, such as M31. We use the ratio of C-stars to M-stars\r\nto investigate the metallicity distribution throughout the disk. The C\/M-star ratio is\r\nfound to increase and flatten with galactocentric distance in agreement with viscous disk formation models. The C-star Luminosity function is found to be similar to the SMC and M31 making C-stars possible distance indicators.","language":"en"},{"key":"dc.format.extent","value":"4265745 bytes","language":null},{"key":"dc.format.mimetype","value":"application\/pdf","language":null},{"key":"dc.language.iso","value":"eng","language":"en"},{"key":"dc.publisher","value":"University of British Columbia","language":null},{"key":"dc.rights","value":"For non-commercial purposes only, such as research, private study and education.
