NGC 2419 does not challenge modified newtonian dynamics.

SANDERS R.H.

Abstract (from CDS):

I show that, in the context of modified Newtonian dynamics (MOND), non-isothermal models, approximated by high-order polytropic spheres, are consistent with the observations of the radial distribution of the line-of-sight velocity dispersion in the distant globular cluster, NGC 2419. This calls into question the claim by Ibata et al. that the object constitutes a severe challenge for MOND. In general, the existence and properties of globular clusters are more problematic for LCDM than for MOND.
