We propose an ACIS-S imaging observation of the barred late-type spiral galaxy NGC 2903. Our primary scientific objective is to investigate the star-forming circumnuclear ring and related structures. We will investigate the effects of star formation on the distribution of gas in this ring and on accretion onto any central massive object. We will construct maps of the distribution of hot gas and compare these to the cold gas, warm gas, and stellar morphologies. We will determine whether the hot gas is confined to the disk or is being expelled in galactic outflows, determine the physical properties of the gas (and point sources), and estimate the role of star formation and associated feedback in impeding or enhancing gas accretion onto any central object.
