Observations of magnetically active close binaries with orbital periods of a few days reveal the existence of starspots at preferred longitudes (with respect to the direction of the companion star). We numerically investigate the non-linear dynamics and evolution of magnetic flux tubes in the convection zone of a fast-rotating component of a close binary system and explore whether the tidal effects are able to generate non-uniformities in the surface distribution of erupting flux tubes… 
The impact of meridional circulation on stellar butterfly diagrams and polar caps
Observations of rapidly rotating solar-like stars show a significant mixture of opposite-polarity magnetic fields within their polar regions. To explain these observations, models describing the
Spot activity of late-type stars : a study of II Pegasi and DI Piscium
All stars that have outer convection zones show magnetic activity. This activity strengthens with angular velocity and depth of the convection zone. Cool starspots are believed to be caused by local
Starspots: A Key to the Stellar Dynamo
Magnetic activity similar to that of the Sun is observed on a variety of cool stars with external convection envelopes. Stellar rotation coupled with convective motions generate strong magnetic
Orbital Motion and Magnetic Activity in Close Binaries and Planetary Systems
The connection between orbital period variation and magnetic activity cyclic behaviour in close binaries with late-type components is addressed by discussing recent observational studies of Algols,
Flux tubes, surface magnetism, and the solar dynamo: constraints and open problems
The flux-tube paradigm has proven to be a remarkably useful tool to understand the connection between the dynamo process in the solar interior and its observable manifestations at the surface. After
Roche tomography of cataclysmic variables – VII. The long-term magnetic activity of AE Aqr
We present a long-term study of the secondary star in the cataclysmic variable AE Aqr, using Roche tomography to indirectly image starspots on the stellar surface spanning 8 years of observations.
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
Chromospheric activity in bright contact binary stars
Context. Studying chromospheric activity of contact binaries is an effective way of revealing the magnetic activity processes of these systems. One efficient but somewhat neglected method for this
Imaging the cool stars in the interacting binaries AE Aqr, BV Cen and V426 Oph
It is well known that magnetic activity in late-type stars increases with increasing rotation rate. Using inversion techniques akin to medical imaging, the rotationally broadened profiles from such
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


Instabilities of Magnetic Flux Tubes in a Stellar Convection Zone
Abstract Motivated by the problems of magnetic flux storage and dynamo action in stars with convection zones, we study the equilibrium and stability of magnetic flux tubes under the influence of
We simulate the photospheric magnetic field on very active cool stars using a flux injection and surface distribution model with strictly solar parameters, including an 11 yr sunspot cycle and
Doppler imaging of stellar surface structure - XVIII. The very active RS CVn binary UZ Librae revisited
We present eight Doppler images of UZ Librae from the years 1994, 1996, 1997, 1998 and 2000. These maps indicate a preferred temperature distribution from one year to the other and suggest preferred
Starspot evolution, differential rotation, and magnetic cycles in the chromospherically active binaries lambda andromedae, sigma Geminorum, II Pegasi, and V711 Tauri
We have analyzed 15-19 yr of photoelectric photometry, obtained manually and with automated telescopes, of the chromospherically active binaries lambda And, sigma Gem, II Peg, and V711 Tau. These
Long-term starspot evolution, activity cycle and orbital period variation of SZ Piscium
A sequence of V -band light curves of the active close binary SZ Piscium (F8 V-IV+ K1 IV), extending from 1957 to 1998, is presented and analysed to derive the spot distribution and evolution on the
Long-term starspot evolution, activity cycle and orbital period variation of RT Lacertae
A sequence of V -band light curves of the active close binary RT Lacertae (G5+G9 IV), extending from 1965 to 2000, is presented and analysed to derive the spot distribution and evolution on the
