  • Abstract We discuss recent Chandra and XMM-Newton observations of the bright isolated neutron star RX J1856.5–3754 and suggest that the absence of any line features is due to effects of a high magnetic field strength (∼10 13 G). Using different models for the temperature distribution across the neutron star surface and assuming blackbody emission to fit the optical and X-ray spectrum, we derive a conservative lower limit of the "apparent“ neutron star radius of 16.5 km × (d/117 pc).
