Andromeda Dwarfs in Light of MOND

Abstract

We compare the recently published velocity dispersions for seventeen Andromeda dwarf spheroidals with estimates of the MOND predictions, based on the luminosities of these dwarfs, with reasonable stellar M/L values, and no dark matter. We find that the two are consistent within the uncertainties. We further predict the velocity dispersions of another ten dwarfs for which only photometric data are currently available.

8 pages, 1 Figure, submitted to Astrophys. J. Changes in response to referee's comments. In particular, the range of stellar M/L values used in the MOND predictions narrowed from 1-6 to 1-4 (M/L)(sun). References added
