Contour plot showing the NRS2 derived effective albedo and heat redistribution efficiency (ε) for TOI-1685 b compared to estimates for solar system bodies from Q. Xue et al. (2024), M. Weiner Mansfield et al. (2024). Black and gray error bars represent the 1σ (84%) and 2σ (95%) upper limits for ε, respectively. The red arrow indicates the maximum T_p,day for a blackbody (assuming A_eff = 0 and ϵ = 0.) We adopt A_B = 0.119, 0.75, 0.306, 0.250, and 0.11 for Mercury, Venus, Earth, Mars, and the Moon, respectively. Since the solar system’s terrestrial planets are not tidally locked, we estimate their heat redistribution efficiency using their polar and equatorial temperatures with a given effective albedo. The results are 1σ consistent with the (mostly) airless Moon, Mercury, and Mars and highly inconsistent with Earth-like or Venus-like heat redistribution.
