Abstract

Only seven isolated radio-quiet neutron stars (XINS) emitting thermal X rays are known, too few to address fundamental questions such as the equation of state of degenerate neutron matter. To expand this sample, we have used the Sloan Digital Sky Survey (SDSS) to examine 10,000 ROSAT error circles and identify a dozen X-ray sources lacking plausible optical counterparts. Short Chandra observations of these XINS candidates are underway to pinpoint the sources. The very small Chandra error circle of one observed candidate remains completely optically blank in SDSS, and this ROSAT/Chandra source is a prime new XINS candidate. We propose a 15 ksec XMM observation to obtain high quality X-ray SED information that will elucidate the nature of this intriguing blank-field X-ray source.
