Fig. 10.


Dependence of the final fraction of accreted halo stars on the adopted mass-loss rate of first-generation stars. The lines indicate the fractions adopted by various works: Baumgardt & Sollima (2017, dash-dotted), Martell et al. (2011, dashed), and our study (solid). Here, red lines show the cases that neglect stellar evolution, while blue lines show values where this is accounted for. This calculation adopted a ratio of first- to second-generation stars of 50:50 and an average present-day GC mass of 2.2 × 105M.
