We try to constrain the nuclear Equation-of-State (EoS) and supernova ejecta
models by observations of young neutron stars in our galactic neighbourhood.
There are seven thermally emitting isolated neutron stars known from X-ray and
optical observations, the so-called Magnificent Seven, which are young (few
Myrs), nearby (few hundred pc), and radio-quiet with blackbody-like X-ray
spectra, so that - by observing their surface - we can determine their
luminosity, distance, and temperature, hence, their radius. We also see the
possibility to determine their current neutron star masses and the masses of
their progenitor stars by studying their origin. It is even feasible to find
the neutron star which was born in the supernova, from which those Fe60 atoms
were ejected, which were recently found in the Earth crust.
