Abstract
We present K-band images of 12 Sa galaxies acquired with the Arcetri NICMOS-3 camera, ARNICA. These galaxies were selected to have accurate optical rotation curves; four of them are among the few Sa’s with absorption-line rotation curves, and five have been found to host bulges with anomalous M/L ratios. Radial brightness profiles have been extracted, and fit with a r1/4 bulge and an exponential disk; derived structural parameters are presented. These observations are part of a project to study the dynamics of early-type spirals and their halos.
