Gravitational wave amplitude from Eq. (1), as a function the magnetic field at the surface (pole), B_s, (left), and the gravitational mass (right) for the three models. We once more assumed a family of stars located at a distance of 1 kpc and spinning with a frequency of 1 Hz. The black dots correspond to ∼2-solar-mass star configurations, and the blue ones correspond to 1.4 M_⊙ stars.
