Schematic drawings of the UY Aur binary

Schematic drawings of the UY Aur binary. Left: Redshifted and blueshifted outflows. The primary star (A) shows wide, open, redshifted and blueshifted outflows as well as a redshifted jet (in solid red), while the secondary star (B) shows a blueshifted jet (in solid blue). Redshifted jets from B might be within the solid red outflow area from A. Right: Model of the UY Aur binary and its outflows and jets, showing the wide redshifted and blueshifted outflows of the primary star (A) and the blueshifted jet from the secondary star (B). The dotted red lines indicate where the redshifted jets from the secondary star might be.
