Ballistic mixing: Stellar mergers drive internal mixing in extremely massive stars with implications for proto-globular cluster pollution
Extremely massive stars, with masses of 10^3--10^4 have been proposed as potential sources of the chemical enrichment associated with multiple populations in globular clusters. Early in the main sequence, these stars reach central temperatures of 65 to 75 MK, enabling nucleosynthesis through the CNO, NeNa, and MgAl cyc...
