The effect of a bar on the kinematics of a central ring structure in NGC 4736
Published online by Cambridge University Press: 07 August 2017
Abstract
We analyze the kinematics of the gaseous ring in the central region of NGC 4736 considering an ejection mechanism for the formation of the ring in a non-axisymmetric potential. A barred spiral of strength 10 or 25 per cent of the axisymmetric background is consistent with van der Kruit (1974) observational data.
