Abstract

High-resolution radio imaging of the γ-ray-emitting nova V959 Mon, hosted by a white dwarf and its binary companion, shows that gaseous ejecta are expelled along the poles as a wind from the white dwarf, that denser material drifts out along the equatorial plane, propelled by orbital motion, and that γ-ray production occurs at the interface between these polar and equatorial regions.
