Abstract

The scale lengths of the old stars and ionized gas distributions are compared for similar samples of Virgo Cluster members and field spiral galaxies via H{alpha} and broad R-band surface photometry. While the R-band and H{alpha} scale lengths are, on average, comparable for the combined sample, we find significant differences between the field and cluster samples. While the H{alpha} scale lengths of the field galaxies are a factor of 1.14+/-0.07 longer, on average, than their R-band scale lengths, the H{alpha} scale lengths of Virgo Cluster members are, on average, 20% smaller than their R-band scale lengths.
