Probing magnetic field re-emergence through X-ray observations of radio pulsars

A significant fraction of young neutron stars can experience a strong fallbackepisode after a supernova explosion. The accreted matter screens the magneticfield which slowly diffuses out on a time scale of tens of thousand years whichis much shorter than the cooling timescale. However, no young radio pulsars withreemerged magnetic field have been identified yet. The main goal of thisproposal is to detect for the first time the thermal emission from selected old(spin down age more than 1 Myear) radio pulsars which allows us to confirm thefield reemergence scenario. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
