Spiral Galaxies Rotation Curves with a Logarithmic Corrected Newtonian Gravitational Potential

Understand

We analyze the rotation curves of 10 spiral galaxies with a newtonian potential corrected with an extra logarithmic term, using a disc modelization for the spiral galaxies.

• There is a new constant associated with the extra term in the potential.
• The rotation curve of the chosen sample of spiral galaxies is well reproduced for a given range of the new constant.
• It is argued that this correction can have its origin from string configurations.
