The cataclysmic variable AE Aquarii: B-V colour of the flares
R. K. Zamanov, G. Y. Latev, S. Boeva +3
We report simultaneous observations of the flaring behaviour of the cataclysmic variable star AE Aqr. The observations are in Johnson B and V bands. The colour-magnitude diagrams (…
Multiband optical variability of the blazar OJ 287 during its outbursts in 2015 -- 2016
Alok C. Gupta, A. Agarwal, A. Mishra +31
We present recent optical photometric observations of the blazar OJ 287 taken during September 2015 -- May 2016. Our intense observations of the blazar started in November 2015 and…
The Extremes in Intra-Night Blazar Variability: The S4 0954+65 Case
Rumen Bachev, Anton Strigachev, Evgeni Semkov +4
We present results of optical observations of the extremely violently variable blazar S4 0954+65 on intra-night time scales. The object showed flux changes of up to 100% within a f…
Optical spectroscopy of Be/gamma-ray binaries
R. K. Zamanov, K. A. Stoyanov, J. Marti +4
We report optical spectroscopic observations of the Be/gamma-ray binaries LSI+61303, MWC 148 and MWC 656. The peak separation and equivalent widths of prominent emission lines (H-a…
