Structure
Structure of Exoplanet Demographics, Rogue Worlds & Circumbinary Planets
Population studies must account for detection bias: transits favor short periods and aligned systems, radial velocity favors massive close-in planets, microlensing samples wider separations, and direct imaging favors young luminous giants.

Exoplanet demographics studies planet occurrence as a function of size, mass, period, stellar type, metallicity, and system architecture.
supported · checked Sep 22, 2026Kepler and TESS establish high occurrence rates for small close-in planets, microlensing probes colder planets and unbound candidates, and circumbinary transits demonstrate stable planetary orbits around stellar pairs.
