UBV(RI)c photometry of active stars. VII.
Listed in IVOA Registry (Virtual Observatory)
In the framework of an extensive program focusing on the global properties and evolution of active stars, high-precision UBV(RI)c photometry of 19 selected stars, collected at ESO over the 15-31 March 1991 interval is presented.
Description
Significant evolution of the light curves, period variations and evidence for long-term variability of the global degree of spottedness are found. Most of the spectral classification are discussed.
A flare event was detected for the star HD 127535 = V841 Cen. These observations contribute to the establishment of a time-extended photometric database which can give important clues on topics such as the stability of spotted areas, differential rotation, solar-like cycles and the correlation between inhomogeneities at different atmospheric levels.
