Description
Recent studies suggest that the intensity of the magnetic
field in low-mass X-ray binaries (LMXBs) is much smaller that its
equipartition value. If the black hole in the binary is surrounded by
a DM spike this would strongly suppress the strength of synchrotron
emission from Dark Matter (DM) induced electron--positron pairs. We
analyze the issue in detail and conclude that, instead, the data do
not rule out the possibility that the intensity of the magnetic field
can approach its equipartition value. This confirms that LMXBs are
potentially promising systems to search for DM.
