Query: Constraints on Bosonic Dark Matter From Observations of Old Neutron
  Stars   Baryon interactions with bosonic dark matter are constrained by the potential
for dark matter-rich neutron stars to collapse into black holes. We consider
the effect of dark matter self-interactions and dark matter annihilation on
these bounds, and treat the evolution of the black hole after formation. We
show that, for non-annihilating dark matter, these bounds extend up to $m_X
\sim 10^{5-7}$ GeV, depending on the strength of self-interactions. However,
these bounds are completely unconstraining for annihilating bosonic dark matter
with an annihilation cross-section of $<\sigma_a v> \gtrsim 10^{-38} {\rm cm^3
/s}$. Dark matter decay does not significantly affect these bounds. We thus
show that bosonic dark matter accessible to near-future direct detection
experiments must participate in an annihilation or self-interaction process to
avoid black hole collapse constraints from very old neutron stars.
