A Comparative Study between M30 and M92: M92 is a Merger Remnant with a Large Helium Enhancement
We perform a comparative study of the ex situ second-parameter pair globular clusters (GCs) M30 and M92, having similar metallicities but different horizontal branch morphologies. We obtain similar mean primordial carbon abundances for both clusters. However, M92 shows a large dispersion in carbon d...
