KMT-2019-BLG-1367L b
Astrophysical Synthesis & Habitability Characterization
KMT-2019-BLG-1367L b is a confirmed super-earth exoplanet orbiting the star KMT-2019-BLG-1367L, located approximately 15231.5 light-years (4670 parsecs) from the Solar System. First announced in 2023 by KMTNet using the Microlensing detection technique (detected via relativistic gravitational lensing of a background source star), this world measures 1.85 Earth radii and has a measured mass of 4.08 Earth masses. Combining its mass and radius yields a mean bulk density of 3.55 g/cm³ (an intermediate density indicative of a deep water-ice mantle or dense volatile envelope), a surface gravity of 1.19 g⊕ (11.67 m/s²), and an escape velocity of 16.6 km/s.
ℹ️ Thermal & Atmospheric Regime: Current photometric and spectroscopic constraints for KMT-2019-BLG-1367L b place it outside the conservative habitable zone definition pending further atmospheric characterization.
The host star KMT-2019-BLG-1367L is classified as a stellar host with a mass of 0.25 M☉.
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).
