WebThe sun and the solar system appear to be moving at 200 kilometers per second, or at an … The rotation curve of a disc galaxy (also called a velocity curve) is a plot of the orbital speeds of visible stars or gas in that galaxy versus their radial distance from that galaxy's centre. It is typically rendered graphically as a plot, and the data observed from each side of a spiral galaxy are generally asymmetric, … Meer weergeven In 1932, Jan Hendrik Oort became the first to report that measurements of the stars in the solar neighborhood indicated that they moved faster than expected when a mass distribution based upon visible matter was assumed, … Meer weergeven The rotational dynamics of galaxies are well characterized by their position on the Tully–Fisher relation, which shows that for spiral galaxies the rotational velocity is uniquely … Meer weergeven • Long-slit spectroscopy • Nonsymmetric gravitational theory • List of unsolved problems in physics Meer weergeven 1. ^ Corbelli, E.; Salucci, P.

Meer weergeven In order to accommodate a flat rotation curve, a density profile for a galaxy and its environs must be different than one that is centrally concentrated. Newton's version of Kepler's Third Law implies that the spherically symmetric, radial density profile ρ(r) is: Meer weergeven There have been a number of attempts to solve the problem of galaxy rotation by modifying gravity without invoking dark matter.
