Scientific paper

PSR J0108-1431 is a 170 Myr old, very faint radio pulsar at a distance of about 130 pc, likely the nearest neutron star to Earth. Thanks to its proximity, PSR J0108-1431 offers a unique opportunity to study X-ray emission from a very old, almost dead pulsar. A short Chandra} observation has shown that its X-ray flux is higher than one could expect from such an old pulsar with a very low spin-down luminosity. However, the number of detected counts was too small to definitively characterize its spectrum, and the time resolution too low to detect pulsations. The proposed study of the X-ray spectrum and pulsations of PSR J0108-1431 will provide first definitive results on the X-ray properties of very old pulsars and test the pulsar evolution models.
