Scientific paper

The very soft (57 eV blackbody) and very bright (3.67 ROSAT PSPC cts/sec) ROSAT source RXJ1856.5-3754 was identified recently by HST as a near-by, isolated, old, non-pulsating neutron star. The PSPC spectral blackbody fit indicates a low absorbing column density (correponding to A_V below 0.1 mag), so that this object most certainly is foreground to the R CrA dark cloud at 130 pc. With the LETG spectrum, we plan to perform photospheric spectroscopy, i.e. to check for deviations from a blackbody, e.g. due to a cyclotron emission feature in the Wien tail, or either a H, He, or Fe atmosphere. From the PSPC count rate, we can estimate that a 50 ksec AXAF LETG observation will provide sufficient S/N for distinguishing between these alternatives.
