Variation, with respect to the un-magnetised model, of various quantities along the equilibrium sequence with constant M₀ = 1.68 M_⊙ for purely poloidal 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 line represents our STT results, to be compared to the red line, describing the GR models of Pili et al. (2014, Fig. 7). The arrows show the direction of increasing magnetisation.
