lomb-scargle-periodogram

separate

Lomb-Scargle periodogram for finding periodic signals in unevenly sampled time series data. Use when analyzing light curves, radial velocity data, or any astronomical time series to detect periodic variations. Works for stellar rotation, pulsation, eclipsing binaries, and general periodic phenomena. Based on lightkurve library.

When to use

• **Lomb-Scargle**: General periodic signals (rotation, pulsation, eclipsing binaries)
• **Transit Least Squares (TLS)**: Specifically for exoplanet transits (more sensitive)
• **Box Least Squares (BLS)**: Alternative transit detection method

When not to use

• exoplanet transits (more sensitive methods preferred)
