Do open star clusters evolve toward energy equipartition? (2016)
Journal Article
(2016). Do open star clusters evolve toward energy equipartition?. Monthly Notices of the Royal Astronomical Society, 317-328. https://doi.org/10.1093/mnras/stw998

We investigate whether open clusters (OCs) tend to energy equipartition, by means of direct N-body simulations with a broken power-law mass function. We find that the simulated OCs become strongly mass segregated, but the local velocity dispersion do... Read More about Do open star clusters evolve toward energy equipartition?.
