Using VIRGO/SPM<br> data from solar cycles 23 and 24 we show that solar-cycle variations are<br> measurable in the temporal autocorrelation function of the p modes. Following<br> a method developed for local helioseismology, we measure the p-mode travel<br> times for multiple skips and propose to average these to enhance the<br> signal-to-noise ratio. This method is robust to noise, simpler to implement<br> than peak bagging in the frequency domain, and promising for asteroseismology<br> applications. We estimate that the activity cycles of Sun-like stars may be<br> detectable in long photometric time series.</p></description> </descriptions> </resource>
