Image Details
Caption: Figure 9.
The J vs. J − H brown dwarf and imaged exoplanet color–magnitude diagram reproduced from Figure 5. The photometry for 51 Eri b is shown with the red star. Also plotted on the CMD are the evolutionary tracks for 5 and 14 ﹩{M}_{\mathrm{Jup}}﹩ objects (Marley et al. 2012), with the solid red line and dashed black line, respectively. The models assume a simple gravity dependence for the initiation of the transition. A few ages for the 5 ﹩{M}_{\mathrm{Jup}}﹩ track have been overplotted. The L–T transition for the 5 ﹩{M}_{\mathrm{Jup}}﹩ planet starts at approximately 900 K and 20 Myr, but for a lower-mass planet such as 51 Eri b, it will occur at younger ages.
