Sirius B

LITBond et al. 2017 (HST): T_eff = 25,369 ± 46 K, mass 1.018 ± 0.011 M☉, radius 0.008098 R☉ (≈5,630 km, smaller than Earth), luminosity 0.02448 L☉, cooling age about 126 Myr. It orbits Sirius A (about 9,845 K) every ~50 years (period cited from memory, unverified).

COMPUTEDThe star's colour is a blackbody at the slider temperature through CIE, Bradford-adapted to D65. Pressing "cool" ages it along a toy cooling curve (MODEL), from blue-white through white and yellow-orange toward red, ending in the black dwarf no star has yet become. Nesting: the remnant's orange-to-red history in shells around a white core, then the void.
