Comparison between HB evolutionary tracks for Z = 0.000010, Y = 0.245, and [α/Fe] = 0.00 with M_MS = 0.700 M_⊙ and: (i) M_MS = 0.800 M_⊙ (left panel), and (ii) M_MS = 0.900 M_⊙ (right panel). In each panel, green and yellow lines correspond to the M_min value reached for M_MS = 0.700 M_⊙ and the alternative M_MS value shown in the plot, respectively. Red and black lines correspond to masses in steps of ΔM = 0.010 M_⊙ for M_MS = 0.700 M_⊙ and the alternative M_MS values, respectively. In like vein, red and gray lines correspond to evolutionary tracks for M_MS = 0.700 M_⊙ and the alternative M_MS values, respectively, with masses of M_HB = 0.650 M_⊙, 0.580 M_⊙, 0.560 M_⊙, 0.540 M_⊙, 0.520 M_⊙, and in steps of ΔM = 0.010 M_⊙ for sets with evolutionary tracks that reach masses lower than 0.500 M_⊙.
