Photometric Activity of the Symbiotic Star CH Cyg During 2008–2011
We present results of UBVRC observations of the symbiotic star CH Cyg before and after optical and X-ray bursts in 2009 at various timescales. Rapid variability was found only during a strong burst (U ~ 9.5 mag) in 2009 October, while during the low state, prior to (U ~ 11 mag) and after (U ~ 9.4 ma...

We present results of UBVRC observations of the symbiotic star CH Cyg before and after optical and X-ray bursts in 2009 at various timescales. Rapid variability was found only during a strong burst (U ~ 9.5 mag) in 2009 October, while during the low state, prior to (U ~ 11 mag) and after (U ~ 9.4 mag) the burst rapid variability was not detected. |
