Top panel: decay of ν (red solid) and χ (blue dashed) as functions of time for initial ν = 0.05 Hz, χ = 3^∘ for a toroidally dominated WD—WD1+B_P ( ﹩{B}_{max}^{{\rm{Toroidal}}}=4\times 1{0}^{13}﹩ G, ﹩{B}_{p}^{{\rm{Poloidal}}}=8\times 1{0}^{8}﹩ G) with a magnetosphere. For the same WD, the middle panel shows the variation of luminosities, and the bottom panel shows GW strain decay with time.
