Mal Ruderman (KIPAC, Stanford) . What do we see when we look at the surface of a neutron star from a great distance? ... The new point that is made is a consequence of near-relativistic electron-positron flows expected in the near-magnetosphere's of "young" (not older than about a million years) neutron stars. Because of cyclotron resonance scattering by these pair-flows on surface X-ray and UV emission, we do not see unprocessed suface emission. ...
