Kinematics of ring-shaped nebulae in the LMC. I - The radial velocity field of N70
Abstract
New kinematical data from the ring-shaped nebula N70 in the LMC shows an expansion velocity of 70 km/s. These data, together with the known spectroscopic information can be explained by a shock model. The shock origins are investigated. They are not likely to proceed from stellar winds and should be attributed to an old supernova explosion.
