Transmuted Gravity Wave Signals from Primordial Black Holes
  Primordial black holes (PBHs) interacting with compact stars in binaries lead
to a new class of gravity wave signatures that we explore. A small $10^{-16} -
10^{-7} M_{\odot}$ PBH captured by a neutron star or a white dwarf will
eventually consume the host. The resulting black hole will have a mass of only
$\sim0.5-2.5 M_{\odot}$, not expected from astrophysics. For a double neutron
star binary system this leads to a transmutation into a black hole-neutron star
binary, with a gravity wave signal detectable by the LIGO-VIRGO network. For a
neutron star-white dwarf system this leads to a black hole-white dwarf binary,
with a gravity wave signal detectable by LISA. Other systems, such as
cataclysmic variable binaries, can also undergo transmutations. We describe
gravity wave signals of the transmuted systems, stressing the differences and
similarities with the original binaries. New correlating astrophysical
phenomena, such as a double kilonova, can further help to distinguish these
events. This setup evades constraints on solar mass PBHs and still allows for
PBHs to constitute all of the dark matter. A lack of signal in future searches
could constrain PBH parameter space.
