TOI-6029 b
Astrophysical Synthesis & Habitability Characterization
TOI-6029 b is a confirmed gas giant exoplanet orbiting the star TOI-6029, located approximately 1967.1 light-years (603.12 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 0.3185% across the stellar disk), this world measures 14.392 Earth radii (1.28 Jupiter radii) and has a measured mass of 519.649 Earth masses (1.63 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.96 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 2.51 g⊕ (24.61 m/s²), and an escape velocity of 67.2 km/s.
In its orbital architecture around TOI-6029, TOI-6029 b completes one full revolution every 5.799 Earth days. Its moderate orbital eccentricity of e = 0.091 driving measurable seasonal insolation cycles.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 1484 K (+1211°C / +2212°F) and receiving 806.79 S⊕ (~1,098,047 W/m²), TOI-6029 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-6029 is classified as a stellar host with an effective photospheric temperature of 6,223 K, a radius of 2.338 R☉, a mass of 1.548 M☉, an estimated bolometric luminosity of 7.355 L☉. Stellar evolution modeling indicates an estimated stellar age of 2.31 Gyr and a metallicity of [Fe/H] = 0.37 dex (metal-rich relative to the Sun). From Earth, TOI-6029 shines at apparent V-band magnitude 12.858 (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).
