To study bars and disks as a function of environment, we are using the STAGES ACS HST survey of the Abell 901/902 supercluster (zÃÅ~0.165), along with earlier field studies based the SDSS and the Ohio State University Bright Spiral Galaxy Survey (OSUBSGS). We explore the limitations of traditional methods for characterizing the bar fraction, and in particular highlight uncertainties in disk galaxy selection in cluster environments. We present an alternative approach for exploring the proportion of bars, and investigate the properties of bars as a function of host galaxy color, Sérsic index, stellar mass, star formation rate (SFR), specific SFR, and morphology. | Comment of the Author/Creator: | Date: 2008, August 1, 2008 | External Publication Status: | published | Document Type: | Conference-Paper |
