Millisecond Pulsars as “seismic” detectors — 3 Comments

  1. Dr. Frye
    One is tempted to say that spinning pulsars produce gravity waves, but this is not the case.
    Object geometry governs.
    There must be eccentric geometry like spinning dumbbells or something called quadrapoles
    but not rotating spheres such as pulsars.
    This geometrical view is another affirmation of Einstein’s relativity theory.

  2. Dear Richard, I think I did not describe the science in enough detail. The proposal is NOT to detect gravity waves from binary neutron stars, but rather to use them as gravity wave _detectors_, such that unexpected delays in pulse arrival time are correlated with gravity wave events. I hope this helps? Best, –Dr. Frye

  3. Dr. Frye,
    Some clarification to my comment.
    In addition to your spacetime modification detection concept
    ‘unexpected delays in ‘pulsar’ radio pulse arrival time correlated with colliding neutron star collision gravitational wave events.’
    would ‘quaking’ neutron pulsar geometrical asymmetric modification events as proposed in
    https://arxiv.org/abs/1608.07049
    be a help. Would these ‘quaking’ or pulsar mass shifting events be considered ‘glitches’ in your terminology?
    A normally rotating pulsar with related pulsing radio emission and no GW
    would undergo an asymmetric quaking event with GW emission and altered radio emission due to rotation modification.
    Differing gravitational wave and radio wave arrival times should provide additional spacetime characterization.
    It is understood that such pulsar quaking events may be difficult to detect with current technology but perhaps LISA may do so in a few years.
    All the best, Richard
