GALAXY2 Richtler et al., 2017, The globular cluster system of NGC 1316. IV. Nature of the star cluster complex SH2 # 세줄 요약 # The light of the merger remnant NGC 1316 (Fornax A) is dominated by old and intermediate-age stars but the only sign of current star formation in this big galaxy is the Hii region SH2, an isolated star cluster complex. We want to investigate the nature of this star cluster complex, so the nebular emission lines permit a metallicity determination that can discriminate between a dwarf ga.. 2022. 1. 16. Yoon et al., 2006, Explaining the Color Distributions of Globular Cluster Systems in Elliptical Galaxies # 세줄 요약 # The globular clusters(GC) in most large elliptical galaxies have color-bimodal distribution that means the presence of two cluster subpopulations that have different geneses(ex. Milky Way). But Horizontal-Branch(HB) stars can make nonlinear nature of the metallicity-to-color transformation, a coeval group of old clusters with a unimodal metallicity spread can exhibit color bimodality. .. 2020. 7. 24. 이전 1 다음
