Abstract

Long-term photometric measurements in a sample of ultrashort-period (P ≈ 0.5 days or less) single and binary stars of different interior structures are analysed. A loose correlation exists between the rotational rate and cycle lengths of active stars, regardless of their evolutionary state and the corresponding physical parameters. The shortest cycles are expected for the fastest rotators of the order of 1-2 years, which is reported in this paper.
