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…
