Predictions of the “warm-start” evolutionary models of SB12 for κ And b for a system at Myr. The extreme values of the companion age, T_eff, and luminosities define a range of masses and initial entropies lying between the dashed and dot-dashed curves. We also overlay the initial entropies considered in “hot-start” (open circles) and “cold-start” (dots) models of FM08 (based on Marley et al. 2007).
