    You can also use a variation on this effect to move star systems around. Surround a start with mirrors but instead focusing the light back to the star you make it focus it to a single point on the star. That single point becomes highly excited and erupts plasma at that location.

    Because this is an extremely energetic plasma eruption and it’s only on one side you get movement in the opposite direction. The stars gravity field will pull the rest of the system with it.

    You could only move it in the direction of the stars poles as unless you got really clever with timed pulsing (and I feel like that would be unreliable), you would vaporize any planets in the system.
