MN Draconis - peculiar, active dwarf nova in the period gap
K. Bakowska, A. Olech, R. Pospieszynski +7
Context: We present results of an extensive world-wide observing campaign of MN Draconis. Aims: MN Draconis is a poorly known active dwarf nova in the period gap and is one of the…
SALT observations of southern post-novae
T. Tomov, E. Swierczynski, M. Mikolajewski +1
We report on recent optical observations of the stellar and the nebular remnants of 22 southern post-novae. In this study, for each of our targets, we obtained and analysed long-sl…
Rapid optical variations in KT Eri
K. Ilkiewicz, E. Swierczynski, C. Galan +2
We present optical photometric monitoring of KT Eri (Nova Eridani 2009), a He/N very fast nova which oubursted in November 2009. Our observations include BVRcIc brightness estimati…
Multicolor photometry of SU UMa and U Gem during quiescence, outburst and superoutburst
P. Wychudzki, M. Mikolajewski, M. Wiecek +5
The results of time-resolved observations of SU UMa and U Gem obtained over two-years are presented. Both stars are prototypes of different classes of dwarf novae. We studied brigh…
Four unusual novae observed in Torun: V2362 Cyg, V2467 Cyg, V458 Vul, V2491 Cyg
E. Ragan, M. Mikolajewski, T. Tomov +21
We present photometric and spectral observation for four novae: V2362 Cyg, V2467 Cyg, V458 Vul, V2491 Cyg. All objects belongs to the "fast novae" class. For these stars we observe…
V2491 Cyg - a possible recurrent nova ?
E. Ragan, M. Mikolajewski, T. Tomov +6
Nova V2491 Cyg was discovered on April 10.72 UT 2008 (Nakano, 2008). Here we present spectrophotometric premises that V2491 Cyg can be a good candidate for recurrent nova (RNe). It…
Photometric search of orbital periods in symbiotic stars
M. Wiecek, M. Mikolajewski, T. Tomov +9
We present UBVRI photometry of three symbiotic stars ZZ CMi, TX CVn and AG Peg carried out from 1997 to 2008 in Piwnice Observatory near Torun. To search orbital periods of these s…
Ellipsoidal effect in the symbiotic star YY Her
M. Wiecek, M. Mikolajewski, T. Tomov +3
A new estimation of the orbital period of YY Her on the base of our and published observations is presented. Phased light curves in RI bands show evidently ellipsoidal effect conne…
Multi-ring structure of the eclipsing disk in EE Cep - possible planets?
C. Galan, M. Mikolajewski, T. Tomov +57
The photometric and spectroscopic observational campaign organized for the 2008/9 eclipse of EE Cep revealed features, which indicate that the eclipsing disk in the EE Cep system h…
V2467 Cygni as possible intermediate polar
E. Swierczynski, M. Mikolajewski, T. Tomov +7
We present the results of unfiltered and UBVR_cI_c band CCD photometry fast nova V2467Cyg. Our analysis of the data gives two distinct frequencies corresponding to periods of ~3.8h…
