The Gaia-ESO Survey: Probes of the inner disk abundance gradient
H. R. Jacobson, E. D. Friel, L. Jilkova +41
The nature of the metallicity gradient inside the solar circle (R_GC < 8 kpc) is poorly understood, but studies of Cepheids and a small sample of open clusters suggest that it stee…
New Neutron-Capture Measurements in 23 Open Clusters. I. The R-Process
Jamie C. Overbeek, Eileen D. Friel, Heather R. Jacobson
Neutron-capture elements, those with Z > 35, are the least well-understood in terms of nucleosynthesis and formation environments. The rapid neutron-capture, or r-process, elements…
NGC 7789: An Open Cluster Case Study
Jamie C. Overbeek, Eileen D. Friel, Heather R. Jacobson +3
We have obtained high-resolution spectra of 32 giants in the open cluster NGC 7789 using the Wisconsin-Indiana-Yale-NOAO Hydra spectrograph. We explore differences in atmospheric p…
