Abstract

We have constructed burst models of the stellar population in the Galactic center. Many classes of models can be excluded entirely. Models with an age of 7-8 Myr and an initial mass of less than 4 × 105 M can reproduce the red supergiant stars and stars with the continuum characteristics of IRS 16 and provide the ionizing flux. We show that if IRS 16 is the product of normal stellar evolution associated with a recent star formation burst that currently dominates the energetics of the region, then IRS 16 itself is inconsequential to Galactic center energetics.
