What influence can a companion star have on a planetary nebula's morphology?

Answer

It can alter the outflow pattern through gravitational interactions or accretion disks.

The final shape, or morphology, of a planetary nebula is complex and is not solely determined by the dying star itself. One significant factor influencing this diversity is the presence of a secondary star, meaning the original star was part of a binary system. The gravitational influence exerted by this companion star can significantly manipulate the path and density of the material being ejected. Furthermore, if material is pulled onto an accretion disk around the companion, this interaction can funnel the escaping stellar material into specific, non-spherical outflows, contributing to bipolar or hourglass shapes.
