A deep XMM-Newton look on the "Magnificent Seven" isolated neutron star RX J1605.3+3249
Abstract
The thermally emitting isolated neutron star (INS) RX J1605.3+3249 is the third brightest in the group dubbed the "Magnificent Seven". Magnetic field decay may explain why these neutron stars rotate more slowly and have higher thermal luminosities and magnetic field intensities than standard pulsars of similar age. Previous XMM-Newton observations of the source revealed a shallow and energy-dependent periodic signal, as well as evidence of a fast spin-down. Such intriguing properties suggest a high dipolar magnetic field and an evolution from a magnetar. We targeted the INS with XMM-Newton to confirm its candidate timing solution, understand the energy-dependent amplitude of the modulation, and investigate the origin of the broad and narrow spectral features of the source. We report here the preliminary results of our programme.
