We study the stellar populations and assembly of the nearby spiral galaxy NGC2903's bulge, bar, and outer disc using the VIRUS-P Exploration of NearbyGalaxies IFS survey. We observe NGC 2903 with a spatial resolution of 185 pcusing the Mitchell Spectrograph's 4.25 arcsec fibres at the 2.7 Harlan J. Smithtelescope. Bulge-bar-disc decomposition on the 2MASS Ks-band image of NGC 2903shows that it has ~6%, 6%, and 88%, of its stellar mass in the bulge, bar, andouter disc, respectively, and its bulge has a low Sersic index of ~0.27,suggestive of a disky bulge. We perform stellar population synthesis and findthat the outer disc has 46% of its mass in stars >5 Gyr, 48% in stars between 1and 5 Gyr, and <10% in younger stars. Its stellar bar has 65% of its mass inages 1-5 Gyr and has metallicities similar to the outer disc, suggestive of theevolutionary picture where the bar forms from disc material. Its bulge ismainly composed of old high-metallicity stars though it also has a smallfraction of young stars. We find enhanced metallicity in the spiral arms andcentral region, tracing areas of high star formation as seen in the Halpha map.These results are consistent with the idea that galaxies of low bulge-to-totalmass ratio and low bulge Sersic index like NGC 2903 has not had a recent majormerger event, but has instead grown mostly through minor mergers and secularprocesses.
