Variation, with respect to the un-magnetised model, of various quantities along the equilibrium sequence with constant M₀ = 1.68 M_⊙ for purely toroidal magnetic field. From left to right, top to bottom: central density ρ_c, Komar mass M_k, circumferential radius R_c and quadrupole deformation e. The blue lines represent our STT results, to be compared to the red lines, describing the GR models in Pili et al. (2014, Fig. 2). The cyan dotted lines highlight the de-scalarised configurations; it is connected by the black dashed segments to the magenta dotted lines, which represent the same STT deviations when calculated with respect to the un-magnetised model in GR. The arrows show the direction of increasing magnetisation.
