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…
International observational campaigns of the last two eclipses in EE Cephei: 2003 and 2008/9
C. Gałan, M. Mikołajewski, T. Tomov +87
Two observational campaigns were carried out during the eclipses of EE Cep in 2003 and 2008/9 to verify whether the eclipsing body in the system is indeed a dark disk and to unders…
Synchronization of the G Giant Rotation in the Symbiotic Binary StHa 190?
M. Cikała, M. Mikołajewski, T. Tomov +5
We present an analysis of high resolution spectral observations of the symbiotic star StHa 190. A 30 days period has been derived from radial velocities of the G-type absorption li…
The hot and the cool otbursts in the symbiotic system AG Draconis
M. Cikała, M. Mikołajewski, J. Osiwała +3
In this papper we present the analyses of the six (1998, 1997, 2001, 2002, 2003 and 2005) last outbursts of AG Draconis on the basis of low resolution visual spectroscopy. A new me…
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…
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…
