Rodríguez Física, Astronomía y Matemáticas ISM: RADIO SOURCES RADIO CONTINUUM: ISM PLANETARY NEBULAE: INDIVIDUAL (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 observations.Our comparison indicates that the emission associated with the surroundings of thestellar nucleus decreased by 40% over this period. We tentatively attribute thisdecrease to variations in the ejection of gas from the central star. 2002 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57138215 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.2 Vol.38 |
