Frankfurt physicists set limits on size of neutron stars
(Goethe University Frankfurt) How large is a neutron star? Previous estimates varied from eight to sixteen kilometres. Astrophysicists at the Goethe University Frankfurt and the FIAS have now succeeded in determining the size of neutron stars to within 1.5 kilometres by using an elaborate statistical approach supported by data from the measurement of gravitational waves. The researchers' report appears in the current issue of Physical Review Letters.
