All stars form in clusters, but most clusters break up less than 50 million years after star formation concludes.

The remaining population of confirmed cluster members includes numerous bright stars of spectral types A ( at least 21 ), F ( about 60 ), and G ( about 50 ).

If the binary fraction is 50 %, the total cluster population would be at least 300 individual stars.
