Qualitative behaviour of multiple solutions for NSs in STTs, in terms of the relation of their mass to the central density ρ_c . The black, orange and red sequences represent, respectively, the weakly scalarised solutions 𝒮_w and the strongly scalarised solutions and . Green diamonds mark the position with central densities ρ_c = ρ₁, ρ₂, ρ₃ where two branches have the same mass; triangles select intermediate densities (see e.g. the values in Table 1); ρ_b and ρ_t (magenta circles) represent the lower and upper limits of the central density for which spontaneous scalarisation happens.
