Abstract
We propose a procedure to use gravitational wave signals as a trigger
for electromagnetic follow up of black hole-neutron star coalescing
binaries, based on two recently proposed semi-analytic fits. The first
one, reproduces the mass of the remnant disk surrounding the black hole
which forms after the merging, as a function of some key parameters of
the binary; the second relates the neutron star compactness, i.e.
the
ratio of mass and radius, with its tidal
deformability. This method
allows to assign a probability that the gravitational signal, emitted in
a black hole-neutron star coalescence, is associated
to the formation of
an
accreting disk massive enough to supply the energy needed to power a
short gamma ray burst.
