Sc and neutron-capture abundances in Galactic low- and high-alpha field halo stars
C. K. Fishlock, D. Yong, A. I. Karakas +5
We determine relative abundance ratios for the neutron-capture elements Zr, La, Ce, Nd, and Eu for a sample of 27 Galactic dwarf stars with -1.5 < [Fe/H] <-0.8. We also measure the…
Evolution and nucleosynthesis of asymptotic giant branch stellar models of low metallicity
C. K. Fishlock, A. I. Karakas, M. Lugaro +1
We present stellar evolutionary tracks and nucleosynthetic predictions for a grid of stellar models of low- and intermediate-mass asymptotic giant branch (AGB) stars at (…
The s-Process Enrichment of the Globular Clusters M4 and M22
Luke J. Shingles, Amanda I. Karakas, Raphael Hirschi +4
We investigate the enrichment in elements produced by the slow neutron-capture process (-process) in the globular clusters M4 (NGC 6121) and M22 (NGC 6656). Stars in M4 have hom…
The outer halo globular cluster system of M31 - I. The final PAndAS catalogue
A. P. Huxor, A. D. Mackey, A. M. N. Ferguson +8
We report the discovery of 59 globular clusters (GCs) and two candidate GCs in a search of the halo of M31, primarily via visual inspection of CHFT/MegaCam imagery from the Pan-And…
Iron and neutron-capture element abundance variations in the globular cluster M2 (NGC 7089)
David Yong, Ian U. Roederer, Frank Grundahl +8
We present CN and CH indices and CaII triplet metallicities for 34 giant stars and chemical abundances for 33 elements in 14 giants in the globular cluster M2. Assuming the program…
