TOI-1036 b
Astrophysical Synthesis & Habitability Characterization
TOI-1036 b is a confirmed gas giant exoplanet orbiting the star TOI-1036, located approximately 600.2 light-years (184.02 parsecs) from the Solar System. First announced in 2026 by Transiting Exoplanet Survey Satellite (TESS) using the Transit detection technique (producing an estimated primary transit depth of 0.2403% across the stellar disk), this world measures 6.285 Earth radii (0.56 Jupiter radii) and has a measured mass of 32.5 Earth masses (0.1 Jupiter masses). Combining its mass and radius yields a mean bulk density of 0.72 g/cm³ (a low bulk density dominated by an extended hydrogen-helium gaseous envelope), a surface gravity of 0.82 g⊕ (8.04 m/s²), and an escape velocity of 25.4 km/s.
In its orbital architecture around TOI-1036, TOI-1036 b completes one full revolution every 3.78 Earth days.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 1294 K (+1021°C / +1870°F) and receiving 466.53 S⊕ (~634,945 W/m²), TOI-1036 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TOI-1036 is classified as a stellar host with an effective photospheric temperature of 5,665 K, a radius of 1.1755 R☉, a mass of 1.03 M☉, an estimated bolometric luminosity of 1.277 L☉. From Earth, TOI-1036 shines at apparent V-band magnitude 10.973 (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).
