Dark Matter Distribution in the Vicinity of Stars

It is generally accepted that dark matter must be found throughout galaxies. The observed motion of stars demands that galaxies contain large amounts of dark matter distributed throughout according to a particular density function. However, it is argued in this paper that this assumed density function should apply to all matter in the galaxy, not just dark matter. This paper reasons that in a region where a strong concentration of visible matter is observed, an absence of dark matter ought to be expected. In particular, calculations show that the dark matter density in the expanded solar neighbourhood (a kiloparsec radial extent from the Sun) should be as expected, in agreement with kinematic measurements; however, the immediate solar neighbourhood (within a few parsecs radial extent from the Sun) should be mostly devoid of dark matter, in accordance with the lack of success in finding dark matter using direct detection experiments on Earth.
