Towards an unbiased X-ray inventory of nearby neutron stars
Abstract
X-ray data can help to better understand surface properties and atmospheric composition, magnetospheric interactions, and the geometry of neutron stars. One application of investigating these sources in the X-ray wavelength is to figure out how much of the available energy budget is converted into X-rays, and how this changes over the life span of the neutron star. In this study, we will present the first results of an XMM-Newton survey aimed at a better sampling of the nearby (< 2Kpc) NS population. We also consider archival X-ray data, comparing the X-ray properties of the archival sources with those of our new candidates, and assessing upper limits. We discuss implications for survey optimization and the importance of multi-wavelength constraints. Better sampling of these sources will allow us to re-evaluate the expected X-ray efficiencies in the literature.
