Best-fit MT sequence simulated with MESA from RLO onset (see legend for values) and onward until the donor becomes a WD. In the three panels, the observed properties of the Galactic LMXB GRS 1915+105 are shown, indicated by the gray areas. The light and dark gray areas are centered on the observed values of GRS 1915+105, and each gray contrast spans 1σ on each side, except for M₂, where the lower 2σ limit is truncated at 0. The dashed vertical line is the observed orbital period of 33.85 days of GRS1915+105. The color shows the BH spin parameter a_∗ which for GRS 1915+105 is a_∗> 0.98, and it shows the fastest spin to be below 0.9. The thickening of the color denoting the MT sequence in each panel indicates the part of the evolutionary track for which the model properties are within 2σ of the observed properties of GRS 1915+105 (excluding the BH spin). The sudden spike seen in the top panel is the formation of a WD.
