Rodríguez Física, Astronomía y Matemáticas PLANETARY NEBULAE: INDIVIDUAL (IC 4997) We present high angular resolution (0.100) VLA observations at 7 mm wavelength towards the planetary nebulawith bipolar morphology IC 4997. We detect a compact central structure possibly associated with the inner corereported by Miranda & Torrelles (1998) and discuss whether or not this detection is related to dust emission.The spectral index of the central region has also been derived using observations at other frequencies madewith similar angular resolution. 2002 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57112045 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) Vol.12 |
