OGLE-TR-132 b
Astrophysical Synthesis & Habitability Characterization
OGLE-TR-132 b is a confirmed gas giant exoplanet orbiting the star OGLE-TR-132, located approximately 6564.3 light-years (2012.62 parsecs) from the Solar System. First announced in 2004 by OGLE using the Transit detection technique (producing an estimated primary transit depth of 0.8726% across the stellar disk), this world measures 13.45 Earth radii (1.2 Jupiter radii) and has a measured mass of 375.02 Earth masses (1.18 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.85 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 2.07 g⊕ (20.3 m/s²), and an escape velocity of 59.1 km/s.
In its orbital architecture around OGLE-TR-132, OGLE-TR-132 b completes one full revolution every 1.69 Earth days at a semi-major axis of 0.03035 AU (an ultra-close orbit less than one-seventh of Mercury's 0.387 AU distance from the Sun, where strong stellar tidal forces typically induce synchronous rotation). Its mean orbital velocity is approximately 195.4 km/s (compared to Earth's 29.8 km/s). The planet follows a highly eccentric trajectory (e = 0.6, swinging from 0.0121 AU at periapsis out to 0.0486 AU at apoapsis), pointing to past dynamical scattering or secular gravitational perturbations.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 2013 K (+1740°C / +3164°F) and receiving 2,550.84 S⊕ (~3,471,688 W/m²), OGLE-TR-132 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star OGLE-TR-132 is classified as a warm F-type star of spectral type F5 V with an effective photospheric temperature of 6,210 K, a radius of 1.32 R☉, a mass of 1.305 M☉, an estimated bolometric luminosity of 2.325 L☉. Stellar evolution modeling indicates an estimated stellar age of 1.2 Gyr and a metallicity of [Fe/H] = 0.37 dex (metal-rich relative to the Sun). From Earth, OGLE-TR-132 shines at apparent V-band magnitude 16.536 (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).
