Long-term observations of the classical nova X Serand the activity of post-novae

Popis výsledku v původním jazyce

We show a relation of the classical nova outbursts and the activity of post-novae. A variety of theoptical activities of post-novae exists. Also large changes of the type of activity in the decadesafter the classical nova outburst are observed in some of them. Although the ensemble of systemsin this analysis is incomplete, the similarities in the decaying branches of the outbursts in somepost-novae are the features favoring the dwarf nova outbursts. The features consistent with thedwarf nova outbursts appear mainly in the later phases (years, decades) of the gradual decay ofthe mean luminosity of some post-novae. This suggests that they contain the accretion diskswhich were able to switch from the hot (ionized) state to the thermal-viscous instability (TVI)regime. Such a TVI of the disk can appear in some post-novae even during the first century afterthe classical nova outburst (often sooner after the classical nova outburst in cataclysmic variableswith longer orbital periods). Activity of the mass-donating star in the brightness variations ofsome post-novae can be caused by the appearance and changes of the position of the active regionson the donor.
