CN and CH indexes in stars of NGC 6791
Listed in IVOA Registry (Virtual Observatory)
Low-resolution SDSS/SEGUE spectra have been used to study the behavior of the strengths of the CN and CH molecular bands in stars at different evolutionary stages of the open cluster NGC 6791.
Description
We find a significant spread in the strengths of the CN bands, more than twice that expected from the uncertainties, although the bimodalities observed in globular clusters are not clearly observed here. This behavior is observed not only among red clump objects but also in unevolved stars such as those in the main sequence and lower red giant branch.
In contrast, not all of the stars studied show significant scatter in their CH strengths.
