TOI-2567 b
Astrophysical Synthesis & Habitability Characterization
TOI-2567 b is a confirmed gas giant exoplanet orbiting the star TOI-2567, located approximately 1646.4 light-years (504.78 parsecs) from the Solar System. First announced in 2022 by Transiting Exoplanet Survey Satellite (TESS) using the Transit detection technique (producing an estimated primary transit depth of 0.3532% across the stellar disk), this world measures 10.929 Earth radii (0.98 Jupiter radii) and has a measured mass of 63.884 Earth masses (0.2 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.27 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.53 g⊕ (5.2 m/s²), and an escape velocity of 27 km/s.
In its orbital architecture around TOI-2567, TOI-2567 b completes one full revolution every 5.984 Earth days at a semi-major axis of 0.0672 AU (orbiting interior to Mercury's 0.387 AU benchmark in the Solar System). Its mean orbital velocity is approximately 122.2 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 1352 K (+1079°C / +1974°F) and receiving 558.00 S⊕ (~759,438 W/m²), TOI-2567 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-2567 is classified as a stellar host with an effective photospheric temperature of 5,611 K, a radius of 1.686 R☉, a mass of 1.13 M☉, an estimated bolometric luminosity of 2.528 L☉. Stellar evolution modeling indicates an estimated stellar age of 7.6 Gyr and a metallicity of [Fe/H] = 0.241 dex (metal-rich relative to the Sun). From Earth, TOI-2567 shines at apparent V-band magnitude 12.3 (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).
