CoRoT-14 b
Astrophysical Synthesis & Habitability Characterization
CoRoT-14 b is a confirmed gas giant exoplanet orbiting the star CoRoT-14, located approximately 5690.1 light-years (1744.6 parsecs) from the Solar System. First announced in 2010 by CoRoT using the Transit detection technique (producing an estimated primary transit depth of 0.8573% across the stellar disk), this world measures 12.22 Earth radii (1.09 Jupiter radii) and has a measured mass of 2415.4 Earth masses (7.6 Jupiter masses). Combining its mass and radius yields a mean bulk density of 7.3 g/cm³ (an iron-enriched, high-compression rocky core), a surface gravity of 16.18 g⊕ (158.67 m/s²), and an escape velocity of 157.3 km/s.
In its orbital architecture around CoRoT-14, CoRoT-14 b completes one full revolution every 1.512 Earth days at a semi-major axis of 0.027 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 194.3 km/s (compared to Earth's 29.8 km/s). The orbit is modeled as circular (e = 0.00), maintaining a constant stellar distance throughout its year.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 1952 K (+1679°C / +3054°F) and receiving 1,803.48 S⊕ (~2,454,534 W/m²), CoRoT-14 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star CoRoT-14 is classified as a warm F-type star of spectral type F9 V with an effective photospheric temperature of 6,035 K, a radius of 1.21 R☉, a mass of 1.13 M☉, an estimated bolometric luminosity of 1.742 L☉. Stellar evolution modeling indicates an estimated stellar age of 4.2 Gyr and a metallicity of [Fe/H] = 0.05 dex (near-solar heavy-element abundance). From Earth, CoRoT-14 shines at apparent V-band magnitude 15.932 (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).
