The Rotation Curve of our Galaxy
Applied Mechanics and Materials, 2014The rotation curve of our Galaxy is derived from a large sample of objects with known radial velocities and distances. We collect data as completely as possible, especially the data with accurately measured trigonometric parallaxes. These observations are used to construct a highly accurate rotation curve of the Galaxy.

The Rotation Curve of the Galaxy
1983The determination of the rotation curve of the Galaxy, θ(R), where θ is the circular velocity at galactocentric distance R, involves the synthesis of a large body of complementary (and sometimes contradictory) data. The synthesis has to be guided to some extent by theoretical considerations such as studying the distribution of mass in the Galaxy, i.e ...

The Dynamics of Galaxy Rotational Curves
Space 2006, 2006During the 1980’s, the first astronomical evidence was obtained that appeared to indicate spiral galaxies, (see Figure 1) do not rotate according to Newton’s’ Second Law of Motion: F=MA. The observations suggest that the outer stars in galaxies seem to rotate too fast for the amount of matter we see in the galaxy.

The kinematic effects on the rotation curve of a galaxy
Astrophysics and Space Science, 1988In this paper, it is pointed out that if the spiral galaxy revolves about some common centre as a whole, the rotation curve will be changed by the kinematic effects. The common centre could be the centre of supercluster or the centre of dark matter and luminous matter.

Rotation curves in neutrino-dominated galaxies
Chinese Astronomy and Astrophysics, 1983Abstract A massive neutrino halo will exert important effects on the motion of the galactic stars inside. In this paper, we give a fully relativistic treatment of the galactic velocity curve in the presence of a massive halo. The results are different from the classical Kepler motion, and provides a possible means of verifying the existence of ...
