A Unifying Model

Elmegreen et al., 1997.

- Besides metallicity, discrepancy still exists for luminosity functions of young vs. old globulars. - Old globulars have a Luminosity Function with power law of -2. - Young globulars have a Luminosity Function with power law of -1. - Likely differentation due to relaxed "cooled" state vs. unrelaxed "hot" state. - Expected that young -1 power-law evolves to -2 power-law through two-body relaxation of young clusters - preferential ejection of small stars.
