Geometric albedo (A_g) estimated as a function of the dayside temperature of Kepler-10b. The cyan lines correspond to the 3σ uncertainty in the computation of A_g. The two vertical red lines and orange regions display the theoretical temperatures and associated 1σ error bars, by considering zero Bond albedo and negligible or perfect heat redistribution. The maximum geometric albedo is at 0.74 ± 0.06. The maximum dayside temperature can be as high as 3430(+50∕−40) K in the case of100% thermal emission.
