Lithium abundance analysis for a range of ages of clusters: comparison of A(Li) from the HD 54236 system to several different clusters ranging in age from 35 Myr to 1.2 Gyr (sample clusters and their parameters are from Sestito & Randich 2005). From these comparisons, we can see that the stellar components in the HD 54236 system (shown with red and blue squares for the primary and secondary stars in the eclipsing binary primary HD 54236A) are indicative of a relatively young age: between PMS clusters and older main-sequence clusters.
