Abstract | Sets of dual frequency microwave data on selected chromospherically active stars, from the Australia Telescope Compact Array, have been investigated for their auto and cross-correlation effects. Comparison of cross-correlation peak values with theoretical expectation indicates a high degree of real physical connection between the emission at the pairs of frequencies (4.8 and 8.64 GHz) compared. This fact should help constrain models for the emission mechanism. The timescale of observed time-shifts between the emissions at the two frequencies is consistent, in general, with the underlying energization being propagated by magnetohydrodynamic waves in a compact turbulent medium. © 2002 Elsevier Science B.V.
