OGLE-2013-BLG-0911L b
Astrophysical Synthesis & Habitability Characterization
OGLE-2013-BLG-0911L b is a confirmed gas giant exoplanet orbiting the star OGLE-2013-BLG-0911L, located approximately 10502.2 light-years (3220 parsecs) from the Solar System. First announced in 2019 by OGLE using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 12.5 Earth radii (1.12 Jupiter radii) and has a measured mass of 3020 Earth masses (9.5 Jupiter masses). Combining its mass and radius yields a mean bulk density of 8.53 g/cm³ (an iron-enriched, high-compression rocky core), a surface gravity of 19.33 g⊕ (189.56 m/s²), and an escape velocity of 173.9 km/s.
☁️ Atmospheric Regime (Volatile / Gas Envelope): With a radius of 12.500 R⊕, OGLE-2013-BLG-0911L 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-2013-BLG-0911L is classified as a stellar host with a mass of 0.29 M☉. From Earth, OGLE-2013-BLG-0911L shines at apparent V-band magnitude 26.42 (faint and requiring research-grade or CCD telescopic photometry) in the Southern celestial hemisphere.
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).
