Project Orion will be able to alter the orbit. George Dyson discusses this here.

The annihilation of a positron and electron results in the emission of just a single gamma ray. In the forward direction of the fast moving pulsar, the incoming gamma rays are blue shifted into the wavelength where they have enough energy to become electrons and positrons when they collide with...

The LGM are down inside the neutron star shelter, away from the emitters of x-rays and gamma rays. lol.

NASA has had a program to look at advanced propulsion systems. One of these is matter-anti-matter propellant. I would think that electrons and positrons being created in pulsars would be trapped in their magnetic field. At the poles of the magnetic fields where the field lines come together...

Whoops I made a mistake. B1957+20 is not the Pulsar that is escaping from the Galaxy, but It does have lots of positrons being created and annihilated. http://chandra.harvard.edu/photo/2003/b1957/closer_look.html The one going at galaxy escape velocity (about .37% C ) is B1508+55...

But if it's moving rapidly through the cosmic background radiation and also being hit by gamma rays and x-rays from all sides and if it could convert this energy to electrons and positrons (as happened in the SLAC experiment linked to in my initial question), then the pickings might not be so slim.

But they are squeezed together very tightly. What happens to a photon whose wavelength is larger than the size of a cluster of several such particle items when it hits them? Does it change into positrons and electrons or just get reflected? How is energy and momentum conserved? The neutron...

I am particularly interested in how neutron star interacts with photons (on a microscopic scale). If the neutron star acted like a big particle, its mass would produce almost no Compton effect red shift since the Compton effect red shift is inversely proportional to the mass of the particle...

The fastest moving pulsars are theoretically spinning neutron stars. They probably got their velocity from a kick from a supernova like Project Orion. http://chandra.harvard.edu/photo/2012/igrj11014/ http://chandra.harvard.edu/photo/2003/b1957/closer_look.html As I understand it, neutron stars...
