Descripción
A goal of the IPHAS survey is to determine the frequency and nature of
emission-line sources in the Galactic plane. According to our selection
criteria, K 3-22 is a candidate symbiotic star, but it was previously
classified as a planetary nebula. To determine its nature, we acquired a
low-resolution optical spectrum of K 3-22. Our analysis of our
spectroscopy demonstrates that K 3-22 is indeed a D-type symbiotic star,
because of its high excitation nebular spectrum and the simultaneous
presence of Raman-scattered O vi emission at 6825 Å and 7082
Å, which is detected primarily in symbiotic stars.
Based on observations obtained at the 2.5 m INT telescope of the Isaac
Newton Group of Telescopes in the Spanish Observatorio del Roque de Los
Muchachos of the Instituto de Astrofísica de Canarias. This
publication makes use of data products from the Two Micron All Sky
Survey, which is a joint project of the University of Massachusetts and
the Infrared Processing and Analysis Center/California Institute of
Technology, funded by the National Aeronautics and Space Administration
and the National Science Foundation.

Nebulosas Bipolares
Nuestro proyecto persigue tres objetivos principales: 1) Determinar las condiciones físico-químicas de las nebulosas planetarias con geometría bipolar y de las nebulosas alrededor de estrellas simbióticas. El fin es entender el origen de la bipolaridad y poner a prueba los modelos teóricos que intentan explicar la morfología y la cinemática nebular
