| Abstract |
We reconstruct the initial two-body relaxation time at the half mass
radius for a sample of young ≤ 300 Myr star clusters in the Large
Magellanic cloud. We achieve this by simulating star clusters with 12288
to 131072 stars using direct N-body integration. The equations of motion of all stars are calculated with high precision direct N-body
simulations which include the effects of the evolution of single stars
and binaries. We find that the initial relaxation times of the sample of
observed clusters in the Large Magellanic Cloud ranges from about 200
Myr to about 2Gyr. The reconstructed initial half-mass relaxation times
for these clusters have a much narrower distribution than the currently
observed distribution, which ranges over more than two orders of
magnitude.
