  Recently, a new Solar System population of weakly interacting massive
particle (WIMP) dark matter has been proposed to exist. We investigate the
implications of this population on indirect signals in neutrino telescopes (due
to WIMP annihilations in the Earth) for the case when the WIMP is the lightest
neutralino of the MSSM, the minimal supersymmetric extension of the standard
model. The velocity distribution and capture rate of this new population is
evaluated and the flux of neutrino-induced muons from the center of the Earth
in neutrino telescopes is calculated. The strength of the signal is very
sensitive to the velocity distribution of the new population. We analytically
estimate this distribution using the approximate conservation of the component
of the WIMP angular momentum orthogonal to the ecliptic plane. The non-linear
problem of combining a fixed capture rate from the standard galactic WIMP
population with one rising linearly with time from the new population to obtain
the present-day annihilation rate in the Earth is also solved analytically. We
show that the effects of the new population can be crucial for masses below
around 150 GeV, where enhancements of the predicted muon flux from the center
of the Earth by up to a factor of 100 compared to previously published
estimates occur. As a result of the new WIMP population, the next generation of
neutrino telescopes should be able to probe a much larger region of parameter
space in the mass range 60-130 GeV.
