Thermal emission from three middle-aged pulsars

Middleaged pulsars (about 100500 kyr) provide the opportunity to study thethermal radiation from neutron stars (NSs). Xray observations of these objects,combined with the NS cooling models, can constrain the nature of the superfluidNS interior, the composition of the stellar core, the processes responsible forthe NS cooling, and the NS mass and radius. However, thermal radiation has beendefinitively detected from only few middleaged pulsars so far. We propose toobserve three nearby middleaged pulsars discovered recently in the ParkesSurvey. These observations will allow us to measure the spectral parameters andstudy the thermal component of the pulsars. radiation to constrain the NSthermal evolution models. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
