UBC prof studies disappearing pulsar

Saw this story in other publications, but I didn't see the connection to UBC. The hook in the other stories was that the precession of the pulsar is causing the "beam" to point away from us, and the pulsar appears to vanish. It's still there, we just can't see it.

Or, at least, we can't see the pulses. I wonder if it's visible in X-rays?

According to Dr. Ingrid Stairs, a professor of Physics and Astronomy at the University of British Columbia, at least one of the stars is a pulsar - a fast-spinning, radiation-emitting neutron star. The second may also be a neutron star, or possibly a white dwarf. The two are closer to each other than Mercury is to our Sun, and orbit each other in just days.
