The Effect of Corotation on the Radial Gradient of Metallicity of Spiral Galaxies
arXiv:1002.1340 · doi:10.1017/S1743921310000694
Abstract
The corotation radius in a spiral galaxy is the radius where the spiral pattern speed has the same velocity of the rotation curve. By compiling results 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.
