Scientific paper

Chandra observations of the Compact Central Object 1E 1207.4-5209 in the PKS 1209-51/52 Supernova Remnant allowed us to discover the first absorption lines in the thermal spectrum of a neutron star and the 424 millisecond period of this object. This first discovery of spectral lines allows an opportunity to measure the gravitational redshift at the surface of a NS and constrain the Equation of State of the super-dense matter. The measured gravitational redshift depends on the correct identification of the spectral lines. Multiwavelength observations are needed to constrain the origin of the spectral lines. We propose deep HST imaging observations to search for the optical counterpart of this source and constrain the properties of this unique object.
