Weakly interacting massive particles and neutron stars.

Physical Review D, 1989
Neutron stars are used to set constraints on the characteristics of weakly interacting massive particles (WIMP's) suggested as dark-matter candidates. Some special classes of WIMP's are ruled out because they would be trapped in neutron stars, concentrate towards the star center, and become self-gravitating.

Weakly interacting massive particles and solar oscillations

Nature, 1986
If the Sun were to contain even a minute mass fraction of weakly interacting massive particles (WIMPs), there could be a significant influence on its central thermal structure. In particular, a relative concentration as small as ∼10−11 by number may lower the central temperature sufficiently to bring the predicted electron neutrino detection rate into ...

On the relic, cosmic abundance of stable, weakly interacting massive particles.

Physical Review D, 1986
In the context of the expanding Universe, we solve the Boltzmann equation to obtain the relic abundance of a stable, weakly interacting massive particle species with arbitrary mass and interaction strength. We provide approximate analytic formulas for the evolution of the abundance and the final abundance.

Weakly interacting massive particles, solar neutrinos, and solar oscillations

Nature, 1986
Weakly interacting, massive particles (WIMPs) have recently been proposed as a solution to the solar neutrino problem1–3. Whereas standard solar models consistently predict a detection rate of (high-energy) neutrinos 3 times higher than that observed in the Davis experiment4–6, the presence of hypothetical massive particles in the solar centre would ...

Motion of the Earth and the detection of weakly interacting massive particles.

Physical Review D, 1988
If the galactic halo is composed of weakly interacting massive particles (WIMP's), then cryogenic experiments may be capable of detecting the recoil of nuclei struck by the WIMP's. Earth's motion relative to the galactic halo produces a seasonal modulation in the expected event rate.

Cosmic-ray positrons from annihilation of weakly interacting massive particles in the galaxy.

Physical Review Letters, 1989
The production of cosmic-ray positrons from the annihilation of weakly interacting massive particles (WIMP's) is considered. Conventional supersymmetric-neutralino annihilation generally yields an unobservably small {ital e}{sup +} flux. However, a massive WIMP ({approx gt}20 GeV) with a large annihilation cross section into a single {ital e}{sup +}e ...

Probing the Earth with weakly interacting massive particles

Physical Review D, 1989
Weakly interacting massive particles (WIMP's) with masses approx. >1 GeV are candidates for the dark matter in galactic halos. We discuss the distribution and detectability of coherently interacting particles (such as massive Dirac or scalar neutrinos, solar cosmions, and some Majorana fermions) that have been captured into orbits within the Earth ...
