OGLE-2016-BLG-0613L AB b
Astrophysical Synthesis & Habitability Characterization
OGLE-2016-BLG-0613L AB b is a confirmed gas giant exoplanet orbiting the star OGLE-2016-BLG-0613L AB, located approximately 11121.9 light-years (3410 parsecs) from the Solar System. First announced in 2017 by OGLE using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 13 Earth radii (1.16 Jupiter radii) and has a measured mass of 1330 Earth masses (4.18 Jupiter masses). Combining its mass and radius yields a mean bulk density of 3.34 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 7.87 g⊕ (77.18 m/s²), and an escape velocity of 113.1 km/s.
☁️ Atmospheric Regime (Volatile / Gas Envelope): With a radius of 13.000 R⊕, OGLE-2016-BLG-0613L AB 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 OGLE-2016-BLG-0613L AB is classified as a stellar host with a mass of 0.72 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).
