Strain (σ) induced by m = 2 and m = 1 g₁ modes (blue and red curves, respectively) of a star spinning at ν_⋆ = 30 Hz (top panel) or at ν_⋆ = 63 Hz (middle panel), both with Θ = 30°, and a star spinning at ν_⋆ = 63 Hz with Θ = 80° (bottom panel), all as functions of t, where the merger corresponds to t = 0. The stratification is set through δ = 0.021, as relevant for the later precursor of GRB 090510 (see Sect. 3.1). The horizontal dashed lines represent the breaking threshold; σ_max = 0.04 is adopted here (Baiko & Chugunov 2018). The binary is considered to be symmetric and consists of stars of masses 1.23 M_⊙ with the APR4 EOS.
