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…
Chemical abundances in bright giants of the globular cluster M62 (NGC 6266)
David Yong, Alan Alves Brito, Gary S. Da Costa +8
With the exception of Terzan 5, all the Galactic globular clusters that possess significant metallicity spreads, such as omega Cen and M22, are preferentially the more luminous clu…
