lomb-scargle-periodogramv0.1.0

Astronomers can use Lomb-Scargle periodograms to measure rotation periods of stars from Kepler or TESS light curves. This helps in studying stellar activity, gyrochronology, and exoplanet host star properties.

Pulsating variable stars (e.g., Cepheids, RR Lyrae) produce periodic light variations. Lomb-Scargle periodograms enable classification by extracting precise periods from unevenly sampled data, aiding large survey analyses like OGLE or ZTF.

While BLS/TLS are more sensitive for transits, Lomb-Scargle provides a quick initial period scan for exoplanet candidates in transit surveys. It can identify candidate periods before applying transit-specific methods.

Eclipsing binary stars exhibit periodic dimming. Lomb-Scargle periodograms efficiently determine orbital periods from unevenly sampled light curves, enabling mass and radius measurements.

The method can be applied to any unevenly sampled time series, such as seismic or climate data, to detect periodic signals like seasonal cycles or tidal patterns.

Offer a cloud-based platform that provides Lomb-Scargle periodogram computation as part of a suite of time series analysis tools for astronomers. Users upload light curves and receive periodograms and statistical significance reports.

Provide expert analysis services to research groups or observatories, delivering periodograms and interpretation for their specific datasets. Clients could include university departments, space agencies, or private observatories.

Develop and sell online courses or workshops teaching the usage of Lomb-Scargle periodograms for astronomical time series analysis, targeting graduate students and early-career researchers.
