[vsnet 141] Q) mechanishm of secondary maximum of AG Dra

[tkato@kusastro.kyoto-u.ac.jp]

  J. Pietz has recently pointed out that symbiotic variable AG Dra seems
to be rising again after the main outburst last year (vsnet-obs message).
This phenomenon also seems to be confirmed by VSOLJ observers.  Historical
records of AG Dra by Sonneberg Observatory suggest that such "double maxima"
are rather common in this system.  Does anyone know (or have an idea of)
the mechanism of this phenomenon?
