Time Variation in the Radio Continuum Emission Associated with the Surroundings of the Nucleus of the Planetary Nebula KjPn 8. (2002). Revista Mexicana De Astronomía Y Astrofísica, 38(2), 275-278. https://astronomia.unam.mx/journals/rmxaa/article/view/2002rmxaa..38..275r
Abstract
We present new, high sensitivity, Very Large Array (VLA) continuum observations of the core of KjPn 8 made with arcsecond angular resolution. These observations were compared with similar observations taken 5.5 years earlier, in order to search for variations that seemed to be present in previous observations. Our comparison indicates that the emission associated with the surroundings of the stellar nucleus decreased by 40% over this period. We tentatively attribute this decrease to variations in the ejection of gas from the central star.Similar Articles
