Time Variation in the Radio Continuum Emission Associated with the Surroundings of the Nucleus of the Planetary Nebula KjPn 8

We present new, high sensitivity, Very Large Array (VLA) continuum observationsof the core of KjPn 8 made with arcsecond angular resolution. Theseobservations were compared with similar observations taken 5.5 years earlier, inorder to search for variations that seemed to be present in previous obser...
