Breaks in the Radial Oxygen Abundance and Corotation Radius of Three Spiral Galaxies
S. Scarano, J. R. D. Lepine, M. M. Marcon-Uchida
The correlation between the breaks in the metallicity distribution and the corotation radius of spiral galaxies has been already advocated in the past and is predicted by a chemo-d…

New developments of the ZZ Ceti instability strip: The discovery of eleven new variables
B. G. Castanheira, S. O. Kepler, S. J. Kleinman +2
Using the SOAR 4.1 m telescope, we report on the discovery of low amplitude pulsations for three stars previously reported as Not-Observed-to-Vary (NOV) by Mukadam et al. (2004) an…

The Effect of Corotation on the Radial Gradient of Metallicity of Spiral Galaxies
S. Scarano, J. R. D. Lepine
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 s…
