In the midst of the most prominent CH Cyg outburst, observed between 1977 and 1986, a powerful jet formed. Observations carried out in 1984 and 1985 detected a strong radio outburst occurring shortly after the onset of the visual decline in brightness. In 1996, CH Cyg again faded, only this time more dramatically and approached a much fainter magnitude than before, providing a good opportunity to search for jet structures again. In addition to flux measurements, a high angular resolution radio map resulted, indicating that the radio source is resolved. In particular, the image shows a significant North-South elongation, suggesting a possible jet.
Further research is needed to better understand how the radio jets are formed.
Models of CH Cygni CH Cygni has been described as a unique and distinctive symbiotic system with a light curve that evades simple explanation. The following section describes three different models of CH Cygni that have recently been proposed to explain this unpredictable star. A Triple Star Model Researchers Hinkle et al. This is remarkable because CH Cygni took a long time to reveal its binary nature, and now a triple is suggested. An eclipsing model Skopal et.
