WASP-35 b
Astrophysical Synthesis & Habitability Characterization
WASP-35 b is a confirmed gas giant exoplanet orbiting the star WASP-35, located approximately 659.5 light-years (202.22 parsecs) from the Solar System. First announced in 2011 by SuperWASP using the Transit detection technique (producing an estimated primary transit depth of 1.5301% across the stellar disk), this world measures 14.572 Earth radii (1.3 Jupiter radii) and has a measured mass of 225.659 Earth masses (0.71 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.4 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 1.06 g⊕ (10.4 m/s²), and an escape velocity of 44 km/s.
In its orbital architecture around WASP-35, WASP-35 b completes one full revolution every 3.162 Earth days at a semi-major axis of 0.04317 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 148.5 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 1338 K (+1065°C / +1949°F) and receiving 758.10 S⊕ (~1,031,778 W/m²), WASP-35 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star WASP-35 is classified as a stellar host with an effective photospheric temperature of 5,990 K, a radius of 1.08 R☉, a mass of 1.05 M☉, an estimated bolometric luminosity of 1.347 L☉. Stellar evolution modeling indicates an estimated stellar age of 5 Gyr and a metallicity of [Fe/H] = -0.15 dex (metal-poor relative to the Sun). From Earth, WASP-35 shines at apparent V-band magnitude 10.939 (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).
