内容記述タイプ Abstract
内容記述 Magnetars are a special type of neutron stars, considered to have extreme dipole magnetic fields reaching ∼10^11  T. The magnetar 4U 0142+61, one of the prototypes of this class, was studied in broadband x rays (0.5–70 keV) with the Suzaku observatory. In hard x rays (15–40 keV), its 8.69 sec pulsations suffered slow phase modulations by ±0.7  sec, with a period of ∼15  h. When this effect is interpreted as free precession of the neutron star, the object is inferred to deviate from spherical symmetry by ∼1.6×10^−4 in its moments of inertia. This deformation, when ascribed to magnetic pressure, suggests a strong toroidal magnetic field, ∼10^12  T, residing inside the object. This provides one of the first observational approaches towards toroidal magnetic fields of magnetars.
