The Hertzsprung–Russell (H-R) diagram showing the position of RY Lep. The open box encompasses the whole range of T_eff reported in the literature, while the gray box represents the values derived from our spectroscopic analysis. The evolutionary tracks were computed for X₀ = 0.7, Z = 0.008, and V_rot,0 = 45 km s⁻¹. Lines of constant frequency 4.4415 day⁻¹ correspond to the radial fundamental mode (p₁), first overtone (p₂), and second overtone (p₃).
