Doppler maps and surface differential rotation of EI Eri from the MUSICOS 1998 observations
Zs. Kővári, A. Washuettl, B. H. Foing +4
We present time-series Doppler images of the rapidly-rotating active binary star EI Eri from spectroscopic observations collected during the MUSICOS multi-site campaign in 1998, si…
Multicolour photometry of the M0V+M5V eclipsing binary V405 And
K. Vida, K. Olah, Zs. Kovari +1
We present multicolour photometry and modelling of the active eclipsing binary star V405 And. The components of 0.2 and 0.5 solar masses are just below and above the theoretical li…
Anti-solar differential rotation and surface flow pattern on UZ Librae
K. Vida, Zs. Kővári, M. Švanda +4
We re-investigate UZ Librae spectra obtained at KPNO in 1998 and 2000. From the 1998 data we compose 11 consecutive Doppler images using the Ca I-6439, Fe I-6393 and Fe I-6411 line…
Surface velocity network with anti-solar differential rotation on the active K-giant Geminorum
Zs. Kõvári, J. Bartus, M. Švanda +4
We demonstrate the power of the local correlation tracking technique on stellar data for the first time. We recover the spot migration pattern of the long-period RS CVn-type binary…
