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. ...

This is just like the Calibration XY offset, except that it is typically cleared when you slew to a new object. ...

... The best-known early observations of the Sun from space were the ones made in 1973 from the space station Skylab . ... Field lines of coronal holes, on the other hand, seem to extend far outwards, their ends dragged by the solar wind to the Earth's orbit and far beyond it. ... It was immediately suspected that such bubbles--named "Coronal Mass Ejections" (CMEs) marked the first stage of the development of interplanetary plasma clouds, some of which initiated magnetic storms when they reached Earth. ...
