The fraction of DR5 planet candidates that are genuine planets, instead of unresolved binaries, for different values of apparent stellar mass and semimajor axis. The points are Gaia DR3 exoplanet candidates with mp < 13 MJ, colored based on our current knowledge of their status. Most of the DR3 candidates are close-in giants around low-mass stars, a region of parameter space where we expect severe contamination by unresolved binaries. The confirmed planet Gaia-4 b (G. Stefánsson et al. 2025) and most of the other previously known planets are in regions of higher purity.
