@article { , title = {Chemical abundances in bright giants of the globular cluster M62 (NGC 6266)}, abstract = {With the exception of Terzan 5, all the Galactic globular clusters that possess significant metallicity spreads, such as ω Cen and M22, are preferentially the more luminous clusters with extended horizontal branches. Here we present radial velocities and chemical abundances for seven bright giants in the globular cluster M62, a previously little-studied cluster. With MV = −9.18, M62 is the ninth most luminous Galactic globular cluster and has an extended horizontal branch. Within our sample, we find (i) no evidence for a dispersion in metallicity, [Fe/H], beyond the measurement uncertainties, (ii) star-to-star abundance variations for C, O, Na and Al with the usual correlations between these elements as seen in other globular clusters, and (iii) a global enrichment for the elements Zr, Ba and La at the level [X/Fe] ≃ +0.4 dex. For elements heavier than La, the abundance ratios are consistent with the scaled-solar r-process distribution. Below La, the abundances are anomalous when compared to the scaled-solar s-process or r-process distributions. For these elements, the abundance signature in M62 is in agreement with predictions of the s-process from fast-rotating massive stars, although the high [Rb/Y] ratio we measure may be a challenge to this scenario.}, doi = {10.1093/mnras/stu118}, eissn = {1365-2966}, issn = {0035-8711}, issue = {3}, journal = {Monthly notices of the Royal Astronomical Society}, note = {Authors not affiliated with University of Hull at time of publication.}, pages = {2638-2650}, publicationstatus = {Published}, publisher = {Oxford University Press}, url = {https://hull-repository.worktribe.com/output/436155}, volume = {439}, keyword = {Lasers and Light Matter Interactions, Specialist Research - Other, Stars : abundances, Galaxy : abundances, Globular clusters : individual : NGC 6266}, year = {2014}, author = {Yong, David and Alves Brito, Alan and Da Costa, Gary S. and Alonso-García, Javier and Karakas, Amanda I. and Pignatari, Marco and Roederer, Ian U. and Aoki, Wako and Fishlock, Cherie K. and Grundahl, Frank and Norris, John E.} }
