Some dwarf galaxies are within the Mondian regime at all radii, i.e., the gravitational acceleration provided by the observed baryons is always below the threshold of g † (cid:39) 1 . 2 × 10 − 10 m s − 2 . These dwarf galaxies often show cores, in the sense that assuming Newton’s gravity to explain their rotation curves, the total density profile ρ ( r ) presents a central plateau or core ( d log ρ/d log r → 0 when r → 0). Here we show that under MOND gravity, the existence of this core implies…
