Exoplanet systems as a research area investigate the formation, architecture, dynamics, and physical properties of planetary systems orbiting stars other than the Sun, integrating observational, theoretical, and computational approaches. The field encompasses detection techniques (e.g., transits, radial velocities, direct imaging, microlensing), characterization of planetary masses, radii, atmospheres, and orbits, and statistical studies of population demographics as functions of stellar type, metallicity, and environment. It also addresses disk–planet interactions, migration processes, multi-planet dynamics, and stability, with implications for planet formation theories, comparative planetology, and the occurrence and potential habitability of terrestrial and giant planets in diverse stellar contexts.
The search for life beyond Earth has traditionally focused on exoplanets orbiting sun-like stars, which is a G-type star. However, low-mass stars, which are designated as K-type and M-type stars, have rapidly become a target ...
