Rotation Curve of Galaxies by the Force Induced by Mass of Moving Particles

TL;DR

This paper introduces the Mirinae force, a novel force generated by moving particle mass, which explains galaxy rotation curves without dark matter, matching observed data for the Milky Way.

Contribution

The paper proposes the Mirinae force as an alternative to dark matter, providing a new model for galaxy rotation curves based on relativistic moving mass effects.

Findings

Mirinae force explains circular motion in galactic disks.

It accounts for flat and varied rotation curves in spiral galaxies.

Inner mass of the Milky Way estimated close to observed values.

Abstract

We suggest that there is a novel force which is generated by the mass of relatively moving particles. The new force which we named Mirinae Force is a counterpart of the magnetic force operating between electrically charged moving particles. Instead of using the conventional dark matter, we applied the mirinae force to a particular model system of the spiral galaxy in which most of the galaxy's mass is located within the central region where some portion of the inner mass is in revolving motion at a relativistic speed. The calculation yielded three important results that illustrate the existence of mirinae force and validate the proposed model: First, the mirinae force in this model explains why most of the matters in the galactic disk are in the circular motion which is similar to cycloid. Second, the mirinae force well explains not only the flat rotation curve but also the varied slope of the rotation curve observed in the spiral galaxies. Third, at the flat velocity of 220 Km/s, the inner mass of the Milky Way calculated by using the proposed model is 6.0\times10^11 M\odot, which is very close to 5.5\times10^11 M\odot (r <50 Kpc, including Leo I) estimated by using the latest kinematic information. This means that the mirinae force well takes the place of the dark matter of the Milky Way.
