    Abstract: A two-component, core-mantle, model is developed to estimate the lifetime against destruction via sublimation of close-orbit, terrestrial-mass exoplanets. We specifically focus on the nearest terrestrial exoplanet, α Centauri Bb, since the parent star α Cen B has a reasonably well determined age of 6 ± 1 Gyr. This latter knowledge specifical...
