TOI-7041 b
Astrophysical Synthesis & Habitability Characterization
TOI-7041 b is a confirmed gas giant exoplanet orbiting the star TOI-7041, located approximately 1433.5 light-years (439.52 parsecs) from the Solar System. First announced in 2025 by Transiting Exoplanet Survey Satellite (TESS) using the Transit detection technique (producing an estimated primary transit depth of 0.0654% across the stellar disk), this world measures 11.433 Earth radii (1.02 Jupiter radii) and has a measured mass of 114.418 Earth masses (0.36 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.42 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.88 g⊕ (8.63 m/s²), and an escape velocity of 35.4 km/s.
In its orbital architecture around TOI-7041, TOI-7041 b completes one full revolution every 9.691 Earth days. With a near-circular eccentricity of e = 0.04, the planet experiences minimal orbital distance variation.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 882 K (+609°C / +1128°F) and receiving 143.26 S⊕ (~194,975 W/m²), TOI-7041 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-7041 is classified as a stellar host with an effective photospheric temperature of 4,700 K, a radius of 4.1 R☉, a mass of 1.07 M☉, an estimated bolometric luminosity of 7.36 L☉. Stellar evolution modeling indicates an estimated stellar age of 10.3 Gyr and a metallicity of [Fe/H] = 0.25 dex (metal-rich relative to the Sun). From Earth, TOI-7041 shines at apparent V-band magnitude 11.251 (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).
