TOI-6130 b
Astrophysical Synthesis & Habitability Characterization
TOI-6130 b is a confirmed gas giant exoplanet orbiting the star TOI-6130, located approximately 720.4 light-years (220.88 parsecs) from the Solar System. First announced in 2024 by Transiting Exoplanet Survey Satellite (TESS) using the Transit detection technique (producing an estimated primary transit depth of 0.7588% across the stellar disk), this world measures 14.347 Earth radii (1.28 Jupiter radii) and has a measured mass of 333.72 Earth masses (1.05 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.62 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 1.62 g⊕ (15.89 m/s²), and an escape velocity of 53.9 km/s.
In its orbital architecture around TOI-6130, TOI-6130 b completes one full revolution every 2.393 Earth days at a semi-major axis of 0.036 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 163.7 km/s (compared to Earth's 29.8 km/s). With a near-circular eccentricity of e = 0.036 (ranging from 0.0347 AU at periapsis to 0.0373 AU at apoapsis), the planet experiences minimal orbital distance variation.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 1750 K (+1477°C / +2691°F) and receiving 1,150.00 S⊕ (~1,565,150 W/m²), TOI-6130 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-6130 is classified as a warm F-type star of spectral type F with an effective photospheric temperature of 6,110 K, a radius of 1.51 R☉, a mass of 1.31 M☉, an estimated bolometric luminosity of 2.851 L☉. Stellar evolution modeling indicates an estimated stellar age of 0.3 Gyr and a metallicity of [Fe/H] = 0.28 dex (metal-rich relative to the Sun). From Earth, TOI-6130 shines at apparent V-band magnitude 11.21 (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).
