CoRoT-35 b
Astrophysical Synthesis & Habitability Characterization
CoRoT-35 b is a confirmed gas giant exoplanet orbiting the star CoRoT-35, located approximately 3663.4 light-years (1123.21 parsecs) from the Solar System. First announced in 2022 by CoRoT using the Transit detection technique (producing an estimated primary transit depth of 1.0948% across the stellar disk), this world measures 18.831 Earth radii (1.68 Jupiter radii) and has a measured mass of 349.611 Earth masses (1.1 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.29 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.99 g⊕ (9.71 m/s²), and an escape velocity of 48.2 km/s.
In its orbital architecture around CoRoT-35, CoRoT-35 b completes one full revolution every 3.227 Earth days at a semi-major axis of 0.0429 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 144.6 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 1747 K (+1474°C / +2685°F) and receiving 1,251.86 S⊕ (~1,703,785 W/m²), CoRoT-35 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star CoRoT-35 is classified as a warm F-type star of spectral type F6 V with an effective photospheric temperature of 6,390 K, a radius of 1.65 R☉, a mass of 1.01 M☉, an estimated bolometric luminosity of 4.073 L☉. Stellar evolution modeling indicates an estimated stellar age of 6.1 Gyr and a metallicity of [Fe/H] = -0.5 dex (metal-poor relative to the Sun). From Earth, CoRoT-35 shines at apparent V-band magnitude 15.635 (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).
