Doppler images of the eclipsing binary ER Vulpeculae
We present Doppler images of both components of the eclipsing binary system ER Vul, based on the spectra obtained in 2004 November, 2006 September and 2008 November. The least-squares deconvolution technique is used for ...
Distribution and evolution of starspots on the RS CVn binary II Pegasi in 2004
We present Doppler images of RS CVn-type binary II Peg based on two data sets obtained in 2004 February and November. In order to improve signal-to-noise ratio and reliability,we apply least-squares deconvolution technique ...
