Query: Pulsars as Weber gravitational wave detectors   A gravitational wave passing through a pulsar will lead to a variation in the
moment of inertia of the pulsar affecting its rotation. This will affect the
extremely accurately measured spin rate of the pulsar as well as its pulse
profile (due to induced wobbling depending on the source direction). The effect
will be most pronounced at resonance and should be detectable by accurate
observations of the pulsar signal. The pulsar, in this sense, acts as a
remotely stationed Weber detector of gravitational waves whose signal can be
monitored on earth. With possible gravitational wave sources spread around in
the universe, pulsars in their neighborhoods can provide us a family of
\textit{remote} detectors all of which can be monitored on earth. Even if GW
are detected directly by earth based conventional detectors, such pulsar
detectors can provide additional information for accurate determination of the
source location. This can be of crucial importance for sources which do not
emit any other form of radiation such as black hole mergers. For the
gravitational wave events already detected by LIGO (and Virgo), our proposal
suggests that one should look for specific pulsars which would have been
disturbed by these events, and will transmit this disturbance via their pulse
signals in any foreseeable future. If these future pulsar events can be
predicted with accuracy then a focused effort can be made to detect any
possible changes in the signals of those specific pulsars.
