| Abstract: |
Star-forming rings or `pseudo-rings' are common to early and intermediate-type spiral galaxies, including our own Milky Way. Such ring-like pileups of gas and associated starbirth activity may have helped to build the inner parts of primeval disk galaxies, as exemplified by the discovery of a galaxy at z~1.5 with a UV-bright inner ring. The formation and maintenance of these starbursting rings are often attributed to orbital resonances with rotating bar or `oval' asymmetries in the stellar disks. Such resonant dynamics are indicated by an Ultraviolet-Optical analysis of M 94 (NGC 4736), the nearest galaxy (excepting the Milky Way) which contains an inner starbursting ring. |
