First Analysis of Results of the OH Survey of the Inner Galaxy: Evidence for a Stellar Bar
Published online by Cambridge University Press: 12 April 2016
Abstract
Part of a large survey of the inner galactic Plane (|ℓ| < 45° and |b| < 3° total) in the OH 1612MHz line in search for OH/IR stars is analyzed. We find strong evidence for a central m=2 distortion based on geometrical considerations. The observed deviation from axisymmetry cannot be explained by lopsidedness and agrees with other recent models of the galactic Bar on length, inclination and axis ratio.
