Flat rotation
WebNov 1, 2024 · With this model, flat rotation curves of spiral galaxies are obtained, because the modified Poisson equation approximately meets the requirement of conservation of total energy in Newton's theory ... WebThe rotation speed would then fall steadily with radius outside a radius of ~10 kpc (i.e., Keplerian), since most of the mass in stars is inside of our orbit beyond that distance. (Graphic by R. Pogge) But, the observations show that the rotation speed stays roughly constant (a "flat rotation curve") at large radii!

WebBy rotating it around an axis, not a point. The best way I can think about it is to talk about a magazine. While it is not 2D, when it is closed, it is flat and fairly skinny.

WebMay 16, 2024 · The rotation curve of Figure 6 can be divided into 3 sections: Section 1: from 0 to r 1, the rotation velocity linearly increases with the distance from the galactic center.. Section 2: from r 1 to r 2, the rotation velocity gradually flats off from linearity relationship.. Section 3: from r 2 to the edge R of the galactic disc, the rotation velocity …
WebA flat rotation curve means that the velocity does not increase or decrease with radius. In effect, v is a constant. G is also a constant, so we deduce that: M G ∝ r. This result is remarkable.
