The Effect of the Corotation on the Radial Gradient of Metallicity of Spiral Galaxies
Published online by Cambridge University Press: 09 March 2010
Abstract
The corotation radius in a spiral galaxy is the place where the spiral pattern speed has the same velocity of the rotation curve. By compiling results coming from the literature for 20 spiral galaxies we verified a strong correlation between the radius of the minima or inflections of the metallicity distribution and the corotation radius.
