Investigating the Consistency of Stellar Evolution Models with Globular
  Cluster Observations via the Red Giant Branch Bump
  Synthetic RGBB magnitudes are generated with the most recent theoretical
stellar evolution models computed with the Dartmouth Stellar Evolution Program
(DSEP) code. They are compared to the observational work of Nataf et al., who
present RGBB magnitudes for 72 globular clusters. A DSEP model using a chemical
composition with enhanced $\alpha$ capture [$\alpha$/Fe] $ =+0.4$ and an age of
13 Gyr shows agreement with observations over metallicities ranging from [Fe/H]
= $0$ to [Fe/H] $\approx-1.5$, with discrepancy emerging at lower
metallicities.
