An illumination effect and an eccentric orbit for the symbiotic binary PU Vul revealed by 32 years of optical spectroscopy
Virginia A. Cúneo, Scott J. Kenyon, Mercedes N. Gómez +3
We analyze 32 years of optical spectra and photometry for the symbiotic binary PU Vul. Light curves for the He I 4471, He II 4686 and H 4861 emission lines reveal…
Ellipsoidal variability of symbiotic giants
J. Mikolajewska, E. A. Kolotilov, S. Yu. Shugarov +2
One of fundamental questions in relation to symbiotic binaries is the process of mass transfer - Roche lobe overflow or stellar wind - and possibility of an accretion disc formatio…
The secondary minimum in YY Her: Evidence for a tidally distorted giant
J. Mikolajewska, E. A. Kolotilov, S. Yu. Shugarov +1
We present and analyze quiescent UBVRI light curves of the classical symbiotic binary YY Her. We show that the secondary minimum, which is clearly visible only in the quiescent VRI…
Flickering in FU Orionis
Scott J. Kenyon, E. A. Kolotilov, M. A. Ibragimov +1
We analyze new and published optical photometric data of FU Orionis, an eruptive pre-main sequence star. The outburst consists of a 5.5 mag rise at B with an e-folding timescale of…
