Multifrequency study of the very slow nova V723 Cas

Chochol, D.; Vittone, A. A.; Pribulla, T.

Multifrequency behaviour of the very slow nova V723 Cas is reviewed. The long-term photometry of the object revealed the orbital period 0.693265 days of the binary, quasi-periodic oscillations in the envelope of the burst white dwarf and 182 days periodicity of activity due to the mass transfer bursts from the red to the white dwarf probably cause…
