Luminosity class of the symbiotic stars 4U1954+319 and ZZ CMi

R. Zamanov, K. A. Stoyanov, G. Latev +8

We performed optical photometry and spectral observations of the symbiotic stars 4U1954+319 and ZZ CMi. For 4U1954+319 using high-resolution spectra we measure the equivalent width…

Accretion in the recurrent nova T CrB: Linking the superactive state to the predicted outburst

R. Zamanov, S. Boeva, G. Y. Latev +6

Context: T CrB (NOVA CrB 1946) is a famous recurrent nova with a recurrence timescale of 80 years. Aims: We aim to estimate the colours, luminosity, and mass-accretion rate for T C…

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…

Pre-outburst signal in the light curves of the recurrent novae RS Oph and T CrB

R. K. Zamanov, V. Marchev, J. Marti +1

Pre-outburst signal (a decrease of the optical brightness) just before the outburst is clearly detected in the observations of the T CrB obtained before and during the 1946 outburs…

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…

Superhumps in the cataclysmic variable BG Tri

S. Y. Stefanov, G. Latev, S. Boeva +1

We present a detailed photometric study of the bright cataclysmic variable BG Tri using ground-based observations mainly from Rozhen Observatory, ASAS-SN, TESS, and WASP sky survey…
