Kepler-1932 b
Astrophysical Synthesis & Habitability Characterization
Kepler-1932 b is a confirmed super-earth exoplanet orbiting the star Kepler-1932, located approximately 2327.9 light-years (713.73 parsecs) from the Solar System. First announced in 2021 by Kepler using the Transit detection technique (producing an estimated primary transit depth of 0.029% across the stellar disk), this world measures 1.515 Earth radii and has a measured mass of 2.91 Earth masses. Combining its mass and radius yields a mean bulk density of 4.61 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.27 g⊕ (12.45 m/s²), and an escape velocity of 15.5 km/s.
In its orbital architecture around Kepler-1932, Kepler-1932 b completes one full revolution every 0.524 Earth days at a semi-major axis of 0.0123 AU (an ultra-close orbit less than one-seventh of Mercury's 0.387 AU distance from the Sun, where strong stellar tidal forces typically induce synchronous rotation). Its mean orbital velocity is approximately 255.3 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 1891 K (+1618°C / +2944°F) and receiving 2,799.90 S⊕ (~3,810,664 W/m²), Kepler-1932 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star Kepler-1932 is classified as a stellar host with an effective photospheric temperature of 5,278 K, a radius of 0.815 R☉, a mass of 0.911 M☉, an estimated bolometric luminosity of 0.462 L☉. Stellar evolution modeling indicates an estimated stellar age of 1.45 Gyr and a metallicity of [Fe/H] = 0.14 dex (metal-rich relative to the Sun). From Earth, Kepler-1932 shines at apparent V-band magnitude 15.286 (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).
