A simple kinematic modeling for flattened S0 galaxies
Abstract
We present mass models for three S0 galaxies with a strong disk component observed almost on edge (NGC 2732, NGC 4111, and NGC 4350). For the analytical representation of the surface-brightness distribution, the method of Multi- Gaussian Expansion, first presented by Monnet et al. (\cite{MBE92}: A&A 253, 366) is applied to V-band surface photometry. A simplified dynamical model is adopted, and the calculated kinematic profiles are compared to long-slit spectroscopic data; overall agreement is reached, except for the innermost region, where additional mass is needed for all three galaxies. We discuss possible applications. Based in part on observations collected at the Observatoire de Haute-Provence.
