abstract = "In one of our previous articles we have considered the role of a
time dependent magnetic ellipticity on the pulsars' braking
indices and on the putative gravitational waves these objects can
emit. Since only nine of more than 2000 known pulsars have
accurately measured braking indices, it is of interest to extend
this study to all known pulsars, in particular as regards
gravitational wave generation. To do so, as shown in our previous
article, we need to know some pulsars' observable quantities such
as: periods and their time derivatives, and estimated distances to
the Earth. Moreover, we also need to know the pulsars' masses and
radii, for which we are adopting current fiducial values. Our
results show that the gravitational wave amplitude is at best h
similar to 10(-28). This leads to a pessimistic prospect for the
detection of gravitational waves generated by these pulsars, even
for Advanced LIGO and Advanced Virgo, and the planned Einstein
Telescope, if the ellipticity has a magnetic origin.",
