It is one the few galaxies in our local Universe that shows Halpha emission in its extreme outer disk. It is an isolated galaxy and is located in the interior of a nearby void. Earlier studies have shown that it it has filamentary HI associated with its outer disk, which could be due to cold gas accretion from the intergalactic medium or the infall of high latitude clouds onto its disk. In this presentation we use archival HI and near-infrared data to correlate the star formation traced by FUV emission with the stellar and gas disk in NGC6946. Our goal is to understand the nature of star formation in the metal poor outer disk and compare it with the star forming complexes in the inner regions. We present some early results of our study. |
