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…

Accretion Events in Binary Systems: AZ Cas and VV Cep
C. Gałan, M. Mikołajewski, T. Tomov +13
The sudden lengthening of orbital period of VV Cep eclipsing binary by about 1% was observed in the last epoch. The mass transfer and/or mass loss are most possible explanations of…
