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

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 no...

Complex long-term activity of the post-nova XSerpentis

Aims. X Ser is a cataclysmic variable (CV) which erupted as a classical nova in 1903. In this work we use over 100 years of photometry to characterize the long-term light curve of XSer, with the aim of interpreting the post-nova act...

A Survey of Novae in M83

The results of the first synoptic survey of novae in the barred spiral and starburst galaxy, M83 (NGC 5236), are presented. A total of 19 novae and one background of the survey, the nova rate in M83 was found to be R = 19(+...

Concerning the Verity of the MMRD Relation for Novae

It has long been claimed that novae reaching the highest luminosity at the peak of their eruptions appear to fade the fastest from maximum light. The relationship between peak) relation. Lightcurve parameters for the most recent sample of M3...

Discovery, photometry, and astrometry of 49 classical nova candidates in M81 galaxy

A use of archival images and intentionally taken new images of M81 galaxy allowed a discovery of 49 classical nova candidates in M81. Acquired positional measurements of these candidates permit us to study a spatial distribution of novae...
