KMT-2016-BLG-1107L b
Astrophysical Synthesis & Habitability Characterization
KMT-2016-BLG-1107L b is a confirmed gas giant exoplanet orbiting the star KMT-2016-BLG-1107L, located approximately 21692.6 light-years (6651 parsecs) from the Solar System. First announced in 2019 by KMTNet using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 13.1 Earth radii (1.17 Jupiter radii) and has a measured mass of 1043 Earth masses (3.28 Jupiter masses). Combining its mass and radius yields a mean bulk density of 2.56 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 6.08 g⊕ (59.62 m/s²), and an escape velocity of 99.8 km/s.
☁️ Atmospheric Regime (Volatile / Gas Envelope): With a radius of 13.100 R⊕, KMT-2016-BLG-1107L b exceeds the empirical ~1.8–2.2 R⊕ Fulton radius valley threshold, indicating a substantial hydrogen-helium or supercritical volatile envelope without a conventional solid terrestrial surface.
The host star KMT-2016-BLG-1107L is classified as a stellar host with a mass of 0.087 M☉.
Methodology: Computed using the Schulze-Makuch et al. (2011) weighted metric comparing physical interior (radius, estimated density) and surface thermal regime (escape velocity, equilibrium temperature).
