Two-body relaxation in modified Newtonian dynamics

  title={Two-body relaxation in modified Newtonian dynamics},
  author={Luca Ciotti and James J. Binney},
A naive extension to MOND of the standard computation of the two-body relaxation time t2b implies that t2b is comparable to the crossing time regardless of the number N of stars in the system. This computation is questionable in view of the non-linearity of MOND’s field equation. A non-standard approach to the calculation of t2b is developed that can be extended to MOND whenever discreteness noise generates force fluctuations that are small compared to the mean-field force. It is shown that… CONTINUE READING
