    Is there any chance these suspactable planets to get catched by Einstein@Home LIGOs?

      don't think so, though I agree it would be nice if they could

      If I understand correctly, the period of the gravity waves transmitted from a rotating system would be the same as the period of the rotation, and I don't think a LIGO can look for gravity waves which last ~years per cycle.

      Pulsars may be a lot further away, but they rotate fast enough to make a signal that (we hope) would be detectable
