BV photometry of the ultracompact binary star GP Com
R. Zamanov, L. Dankova, M. Minev +2
We present optical B and V band photometry of GP Com - an ultracompact binary consisting of an accreting white dwarf and helium secondary component. Our data set contains 7.7 hours…
Periods of outbursts and standstills and parameters variations in two Z Cam stars: Z Cam and AT Cnc
Daniela Boneva, Krasimira Yankova, Denislav Rusev
We present our results on two Z Cam stars: Z Cam and AT Cnc. We apply observational data for the periods that cover the states of outbursts and standstills, which are typical for t…
Post-superhumps maximum on intranight time scales of the AM CVn star CR Boo
Daniela Boneva, Georgi Latev, Svetlana Boeva +2
We present observations of the intranight brightness variability of CR Boo, a member of the AM CVn stars group. The observational data are obtained with the 2m telescope of the Roz…
Recent humps and superhumps observations and an estimation of outburst parameters of the AM CVn star CR Boo
Daniela Boneva, Radoslav Zamanov, Svetlana Boeva +4
We present our observational results of AM CVn star CR Boo in the UBVR bands. Our observational campaign includes data obtained over 5 nights with the National Astronomical Observa…
Mid-Cycle Observations of CR Boo and Estimation of the System's Parameters
Daniela Boneva, Svetlana Boeva, Yanko Nikolov +2
We present observations (with NAO Rozhen and AS Vidojevica telescopes) of the AM Canum Venaticorum (AM CVn) type binary star CR Bootis (CR Boo) in the UBV bands. The data were obta…
Magnetic fields in the accretion disks for various inner boundary conditions
Daniela V. Boneva, Evgeny A. Mikhailov, Maria V. Pashentseva +1
The magnetic fields of accretion disks play an important role in studying their evolution. We may assume that its generation is connected to the dynamo mechanism, which is similar…
The recurrent nova RS Oph - simultaneous B and V band observations of the flickering variability
R. K. Zamanov, S. Boeva, G. Y. Latev +7
We performed 48.6 hours (in 28 nights) of simultaneous B and V band observations of the flickering variability of the recurrent nova RS Oph in quiescence. During the time of our ob…
Density distribution configuration and development of vortical patterns in accreting close binary star system
Daniela Boneva, Lachezar Filipov
We investigate the problem of structures formation in accretion disc zone, resulting from the tidally interaction in close binary star system. We aim to examine the area where the…
Models of Vortices and Spirals in White Dwarf's Accretion Binaries
Daniela Boneva
The main aim in the current survey is to suggest models of the development of structures, such as vortices and spirals, in accretion white dwarf's binaries. Numerical methods and s…
