Scientific paper
Various line of evidence indicate that the Galactic Center has formed stars within the last 10-200 million years. We will search for the O and B stars which should still be on the main sequence and hence will give a better age determination for the last epoch of star formation. Such stars can be distinguished on the basis of careful broadband color measurements. By observing the central 20", a region 2' away, and a region 2 degrees away, we will be able to see whether a time sequence is exhibited as is hinted at in the groundbased data. Parallel observations will extend the study of the stellar population into adjacent regions.
