lomb-scargle-periodogram

To detect periodic signals in unevenly sampled astronomical time series, apply the Lomb-Scargle periodogram to your light curves or radial velocity data. This method identifies dominant periods without requiring uniform data sampling intervals.

The Lomb-Scargle periodogram is used in light curve analysis to reveal underlying cycles by identifying the strongest periodicities. It estimates frequency at maximum power and generates model curves for comparison against unevenly sampled observations.

Yes, you can set minimum and maximum period limits when running a Lomb-Scargle periodogram. Specifying a period range allows you to target specific astronomical phenomena like stellar rotation, pulsations, or eclipsing binaries.

Yes, you need Python with a Lomb-Scargle implementation such as lightkurve to perform uneven-sample period detection. The environment must support specifying period ranges, evaluating peak power, and generating basic model curves.

The best way to find dominant periods in radial velocity data is applying Lomb-Scargle periodogram analysis. It handles uneven sampling effectively, calculating peak power across specified frequency ranges to pinpoint underlying periodic cycles.
