The Interacting Early-Type Binary BD +40°4220 (V729 Cyg): Modeling the Colliding Winds Region

We present an analysis of an extensive set of spectroscopic observations of the mysterious early-type binary BD +40 deg4220. A new orbital solution is derived from the radial velocities of the absorption lines. We confirm that the secondary star is highly overluminous for its mass. The absorption li...
