Quark Stars
BigGar' writes "Astronomers seem to have discovered a new type of star. It would lie between a neutron star and and a black hole in the hierarchy of stars and consist of quark matter. Further observations with the Chandra X-ray telescope will be needed to confirm the results."
I'm sorry, that just seems like wishful thinking to tie your star to a known event, therefor creating a strong case for you. The chances are less than one in a billion that it was the very same star.
