Star with a "comet's" tail.

http://science.nasa.gov/headlines/y2....htm?list83929

Was looking at this wondering how the tail is formed? It doesn't say in the
article, it mentions it's a fast moving star but...

A true comet has the solar wind to form the tail but this star is in
interstellar space. Surely all the material blown off would retain the same
velocity and direction of the star and make a nebula.

It mentions a bow shock too, this would indicate a medium it is travelling
through. Is the interstellar medium dense enough?
