What's a bit strange about this is that the way to move stars is
obvious.  Eric Drexler and I discussed it way back in the 1970s.
There is even a nice painting of a star fixed up this way somewhere.
(The artwork even had a slice out of the light sails to keep planets
illuminated.)

For those who have not heard about it, you hover actively controlled
solar sails over one hemisphere of a star.  This makes the star into a
fusion/photon drive.  The acceleration isn't much, but a G type star
looked like it could cross the average distance between galaxies
before it burned out.

the Feb 2018 Scientific American.
