  • New evidence for a long thin Galactic bar (in contradistinction to the bulge), as well as for the existence of the ring and the truncation of the inner disc, are sought in the DENIS survey. First, we examine DENIS and Two Micron Galactic Survey star counts for the characteristic signatures of an in-plane bar and ring. The star counts in the plane for $30^\circ> l> -30^\circ$ are shown to be highly asymmetric with considerably more sources at positive than at negative longitudes. At $|b|\approx… CONTINUE READING
