  The recent progress in the understanding the physical nature of neutron star
equilibrium configurations and the first observational evidence of a genuinely
short gamma-ray burst, GRB 090227B, allows to give an estimate of the
gravitational waves versus the X and Gamma-ray emission in a short gamma-ray
burst.
