CoRoT-32 b
Astrophysical Synthesis & Habitability Characterization
CoRoT-32 b is a confirmed gas giant exoplanet orbiting the star CoRoT-32, located approximately 1880.9 light-years (576.68 parsecs) from the Solar System. First announced in 2018 by CoRoT using the Transit detection technique (producing an estimated primary transit depth of 0.5497% across the stellar disk), this world measures 6.389 Earth radii (0.57 Jupiter radii) and has a measured mass of 47.675 Earth masses (0.15 Jupiter masses). Combining its mass and radius yields a mean bulk density of 1.01 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 1.17 g⊕ (11.47 m/s²), and an escape velocity of 30.6 km/s.
In its orbital architecture around CoRoT-32, CoRoT-32 b completes one full revolution every 6.718 Earth days at a semi-major axis of 0.071 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 115 km/s (compared to Earth's 29.8 km/s).
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 938 K (+665°C / +1229°F) and receiving 132.26 S⊕ (~180,006 W/m²), CoRoT-32 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star CoRoT-32 is classified as a solar-type yellow star of spectral type G0 VI with an effective photospheric temperature of 5,970 K, a radius of 0.79 R☉, a mass of 1.08 M☉, an estimated bolometric luminosity of 0.711 L☉. Stellar evolution modeling indicates a metallicity of [Fe/H] = 0 dex (near-solar heavy-element abundance). From Earth, CoRoT-32 shines at apparent V-band magnitude 13.626 (faint and requiring research-grade or CCD telescopic photometry) in the Northern 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).
