Revisiting ΔY/ΔZ from multiple main sequences in globular clusters: insight from nearby stars

Portinari, Laura; Casagrande, Luca; Flynn, Chris


For nearby K dwarfs, the broadening of the observed main sequence (MS) at low metallicities is much narrower than expected from isochrones with the standard helium-to-metal enrichment ratio ΔY/ΔZ ∼ 2. Though the latter value fits well the MS around so
