OrbDot: A Python package for studying the secular evolution of exoplanet orbits

Gradual changes in exoplanet orbits, known as secular variations, can be detected through observations of transits, eclipses, and radial velocities that span multiple decades in time.Their detection and characterization enable the study of a wide range of dynamical phenomena, such as orbital decay and precession, which operate on timescales of millions of years.Under certain conditions, measurements of secular variations can even probe the interior structure of exoplanets, providing a unique tool for understanding exoplanet formation and evolution.
