Abstract

We have measured gas and stellar velocity dispersions in 5 circumnuclear starforming regions (CNSFRs) and the nucleus of the barred spiral galaxy NGC 3351. The stellar dispersions have been measured from high resolution spectra of the CaII λ λ 8494, 8542, 8662 Å triplet lines (CaT), while the gas velocity dispersions have been measured by Gaussian fits to the Hβ λ 4861Å and [OIII] λ 5007Å lines on high dispersion spectra. We determined the line of sight stellar velocity along each slit. Extractions were selected such as to maximize signal-to-noise while preserving spatial resolution.
