TIC 231949697 b
Astrophysical Synthesis & Habitability Characterization
TIC 231949697 b is a confirmed super-earth exoplanet orbiting the star TIC 231949697, located approximately 163.9 light-years (50.24 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 0.0809% across the stellar disk), this world measures 1.528 Earth radii and has a measured mass of 2.95 Earth masses. Combining its mass and radius yields a mean bulk density of 4.56 g/cm³ (a terrestrial silicate-iron composition comparable to Earth (5.51 g/cm³)), a surface gravity of 1.26 g⊕ (12.36 m/s²), and an escape velocity of 15.5 km/s.
In its orbital architecture around TIC 231949697, TIC 231949697 b completes one full revolution every 0.907 Earth days.
⚠️ Thermal Regime (Irradiated / Hot Zone): At an equilibrium temperature of 983 K (+710°C / +1310°F) and receiving 154.97 S⊕ (~210,914 W/m²), TIC 231949697 b orbits interior to the runaway greenhouse boundary where surface liquid water cannot persist.
The host star TIC 231949697 is classified as a stellar host with an effective photospheric temperature of 3,451 K, a radius of 0.4926 R☉, a mass of 0.4907 M☉, an estimated bolometric luminosity of 0.031 L☉. From Earth, TIC 231949697 shines at apparent V-band magnitude 13.188 (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).
