WISE J033605.05-014350.4 b
Astrophysical Synthesis & Habitability Characterization
WISE J033605.05-014350.4 b is a confirmed gas giant exoplanet orbiting the star WISE J033605.05-014350.4. First announced in 2023 by James Webb Space Telescope (JWST) using the Imaging detection technique (resolved directly via high-contrast coronagraphic or interferometric imaging), this world measures 12.6 Earth radii (1.12 Jupiter radii) and has a measured mass of 2622.084 Earth masses (8.25 Jupiter masses). Combining its mass and radius yields a mean bulk density of 7.23 g/cm³ (an iron-enriched, high-compression rocky core), a surface gravity of 16.52 g⊕ (162.01 m/s²), and an escape velocity of 161.4 km/s.
In its orbital architecture around WISE J033605.05-014350.4, WISE J033605.05-014350.4 b completes one full revolution every 2560 Earth days (7.01Julian years) at a semi-major axis of 0.97 AU (comparable to the inner terrestrial zone between Venus, Earth at 1.00 AU, and Mars at 1.52 AU). Its mean orbital velocity is approximately 4.1 km/s (compared to Earth's 29.8 km/s).
☁️ Atmospheric Regime (Volatile / Gas Envelope): With a radius of 12.600 R⊕, WISE J033605.05-014350.4 b exceeds the empirical ~1.8–2.2 R⊕ Fulton radius valley threshold, indicating a substantial hydrogen-helium or supercritical volatile envelope without a conventional solid terrestrial surface.
The host star WISE J033605.05-014350.4 is classified as a stellar host with an effective photospheric temperature of 415 K, a mass of 0.0131 M☉. Stellar evolution modeling indicates an estimated stellar age of 3 Gyr.
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).
