Long-term monitoring of active stars. VI. UBV(RI)c observations collected in Sep.-Oct. 1990.

Abstract (from CDS):

In the framework of an extensive program focusing on the global properties and evolution of active stars, high-precision UBV(RI)c photometry of 9 selected stars, collected at the European Southern Observatory over the intervals 7-17 September and 30 September - 10 October 1990, is presented. Significant evolution of the light curves, period variations and evidence for long-term variability of the global degree of spottedness are found. Some of the spectral classifications are discussed. These observations contribute to the establishment of a time-extended photometric database which can give important clues on topics such as the stability of the spotted areas, differential rotation, solar-like cycles and the correlation between inhomogeneities at different atmospheric levels.
