Pairs of “HH knots” in PV Ceph

Pairs at similar distances=“jets”, and connectors should pass through source Warning: Hypothetical!

Changes in jet angle can be explained by “precession” of the star (like a wobbling top) Warning: Hypothetical!

But… Jets from PV Ceph “Miss” the Source Can’t be (just) precession.

Where are the midway points?

What if PV Ceph was moving, fast?

? PV Ceph How did it do this?

Must be “gravity”! Close encounter with another star How did it do this?
