Selected evolutionary tracks with initial secondary mass of ﹩1.0\,{M}_{\odot }﹩ and orbital period of 1.0 day but different evaporation efficiencies and AML modes. Shown from top to bottom are the evolutionary timescale (thick lines for thermal timescale and thin dashed lines for mass-loss timescale), radius, age, and mass-loss rate of the secondary (thick lines for RLOF and thin dashed lines for evaporative mass loss).
