WebWe find that the halo of Andromeda has a mass of ~ 12.3 +18-6 x 10 11 M sun, together with a scalelength of ~90kpc and a predominantly isotropic velocity distribution. For comparison, our earlier estimate for the Milky Way halo is 19 +36-17 x 10 11 M sun. WebThe interstellar dust in M110 has a mass of (1.1–1.8) × 104 M☉ with a temperature of 18–22 K, and the interstellar gas has (4–7) × 106 M☉. The inner region has sweeping deficiencies in its interstellar medium IM, most likely expelled by supernova explosions.
