Phase-resolved Spectroscopy of the Thermally-emitting PSR J1740+1000

Our analysis of a short Chandra ACIS observation of PSR J1740+1000 has shownthat it is a bright Xray source with the spectrum dominated by thermalemission. The spectrum fits best with a twocomponent blackbody model althoughthe presence of an additional powerlaw component is not excluded by the currentdata. Pulsations at the radio period of 154 ms are detected at a 3sigma level.We propose an observation of this middleaged (100 kyr) pulsar with EPIC toaccurately measure its spectrum and pulse profile and perform phaseresolvedspectroscopy and energyresolved timing. This would unambiguously establish thenature and orgins of the pulsar.s spectral components and add to ourunderstanding of the neutron star properties and evolution. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
