The statistics of albedo and heat recirculation on hot exoplanets

NB Cowan, E Agol - The Astrophysical Journal, 2011 - iopscience.iop.org
If both the day-side and night-side effective temperatures of a planet can be measured, it is
possible to estimate its Bond albedo, 0< AB< 1, as well as its day–night heat redistribution …
