We describe a sample of thermally emitting neutron stars discovered in theROSAT All-Sky Survey. We discuss the basic observational properties of theseobjects and conclude that they are nearby, middle-aged pulsars with moderatemagnetic fields that we see through their cooling radiation. While theseobjects are potentially very useful as probes of matter at very high densitiesand magnetic fields, our lack of understanding of their surface emission limitstheir current utility. We discuss this and other outstanding problems: thespectral evolution of one sources and the relation of this population to theoverall pulsar population.Comment: 9 pages, one table, 3 figures.
