Internal Kinematics of M10 and M71
N. A. Barth, J. M. Gerber, O. M. Boberg +2
We present a study of the internal kinematics of two globular clusters, M10 (NGC 6254) and M71 (NGC 6838), using individual radial velocity (RV) measurements obtained from observat…
Identifying Multiple Populations in M71 Using CN
Jeffrey M. Gerber, Eileen D. Friel, Enrico Vesperini
We have observed the CN features at 3800 ~Å~ and 4120~ Å~ as well as the CH band at 4300~Å~ for 145 evolved stars in the Galactic globular cluster M71 using the multi-o…
Carbon Isotope Ratios in M10 Giants
Z. G. Maas, J. M. Gerber, Alex Deibel +1
We measured carbon abundances and the ratio in 31 giant branch stars with previous CN and CH band measurements that span -2.33 M …
Carbon Abundance Inhomogeneities and Deep Mixing Rates in Galactic Globular Clusters
Jeffrey M. Gerber, Michael M. Briley, Graeme H. Smith
Among stars in Galactic globular clusters the carbon abundance tends to decrease with increasing luminosity on the upper red giant branch, particularly within the lowest metallicit…
