Photometry and Morphology of Very Isolated S0 Galaxies
Abstract
We gathered BVR images of fifteen very isolated S0 galaxies from the McDonald Observatory 0.8m telescope using the Prime Focus Camera to perform a comprehensive photometric and morphological survey of S0 galaxies in very isolated environments. We computed standard galaxy photometric parameters including magnitudes and color. We then performed ellipse fitting to determine the shape and orientation of the disks of the galaxies. Finally we calculated quartile radii and the corresponding concentration indices to quantify stellar distribution throughout the galaxy. The results of our data analysis will be used to characterize very isolated S0 galaxies as an environmentally distinct subspecies of S0 galaxies.
