Flickering of accreting white dwarfs: the remarkable amplitude-flux relation and disc viscosity
R. K. Zamanov, S. Boeva, G. Latev +7
We analyze optical photometric data of short term variability (flickering) of accreting white dwarfs in cataclysmic variables (KR Aur, MV Lyr, V794 Aql, TT Ari, V425 Cas), recurren…
Circumstellar discs in X/gamma-ray binaries: first results from the Echelle spectrograph
R. Zamanov, K. Stoyanov, J. Martí
Here we report our first spectral observations of Be/X-ray and gamma-ray binaries obtained with the new Echelle spectrograph of the National Astronomical Observatory Rozhen. For fo…
The unusual photometric variability of the PMS star GM Cep
E. Semkov, S. Ibryamov, S. Peneva +6
Results from UBVRI photometric observations of the pre-main sequence star GM Cep obtained in the period April 2011 - August 2014 are reported in the paper. Presented data are a con…
Difference between the optical flickering colours of cataclysmic variables and symbiotic recurrent novae
R. Zamanov, S. Boeva, G. Latev +2
We performed simultaneous observations in 3 bands (UBV) of the flickering variability of the recurrent novae RS Oph and T CrB at quiescence. Using new and published data, we compar…
Optical Flickering of the recurrent nova RS Ophiuchi: amplitude - flux relation
R. Zamanov, G. Latev, S. Boeva +7
We report observations of the flickering variability of the symbiotic recurrent nova RS~Oph at quiescence in five bands (). We find evidence of a correlation between the pea…
