Abstract EN

The spiral galaxy is basically a disk of stars with large central bulge and halo.

In this paper density distribution profiles of bulge, disk with arms and dark halo of spiral Galaxy are discussed , also in this paper the new profile of dark matter density distribution can be suggested, and then plot spiral galaxy such as the Milky Way rotation curve for above components.

The results show that the new profile of dark matter density distribution provides a good agreement with the observed rotation curve of Milky Way galaxy.-
