18 Jan 2007 | | Abstract: | High precision planet orbital data extracted from direct observation, spacecraft explorations and laser ranging techniques enable to put a strong constraint on the maximal dark matter density of a spherical halo centered around the Sun. The maximal density at Earth’s location is of the order $10^5$ ${
m GeV/cm^3}$ and shows only a mild dependence on the slope of the halo profile, taken between 0 and -2. This bound is somewhat better than that obtained from the perihelion precession limits. | | Source: | arXiv, astro-ph/0701542 | | Services: | Forum | Review | PDF | Favorites | |
