The far-UV bow shock of the nearest millisecond pulsar J0437-4715
Abstract
Most pulsars are moving supersonically through the interstellar medium. The interaction between the pulsar wind and the ambient medium gives rise to a bow shocks. Most of the bow shock pulsar wind nebulae have been found in X-rays while some are seen in Halpha emission. In HST observations of the nearest millisecond pulsar J0437-4715, for which an Halpha bow shock had been previously detected, we discovered a bow shock of a similar shape at far-UV wavelengths (125-220 um). Bow shocks at these wavelengths have neither been seen nor predicted by bow-shock models. We will discuss the properties of the far-UV bow shock emission and implications of our discovery.
