The Stellar Populations of M33's Outer Regions IV: Inflow History and Chemical Evolution
Michael K. Barker, Ata Sarajedini
We have modelled the observed color-magnitude diagram (CMD) at one location in M33's outskirts under the framework of a simple chemical evolution scenario which adopts instantaneou…
The Stellar Populations of M33's Outer Regions III: Star Formation History
Michael K. Barker, Ata Sarajedini, Doug Geisler +2
We present a detailed analysis of the star formation history (SFH) of three fields in M33 located ~ 4 - 6 visual scale lengths from its nucleus. These fields were imaged with the A…
The Stellar Populations of M33's Outer Regions II: Deep ACS Imaging
Michael K. Barker, Ata Sarajedini, Doug Geisler +2
Studying the stellar populations in the outskirts of spiral galaxies can provide important constraints on their structure, formation, and evolution. To that end, we present VI phot…
The Stellar Populations in the Outer Regions of M33. I. Metallicity Distribution Function
Glenn P. Tiede, Ata Sarajedini, Michael K. Barker
We present deep CCD photometry in the VI passbands using the WIYN 3.5m telescope of a field located approximately 20' southeast of the center of M33; this field includes the region…
