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! WebOct 7, 2016 · A flat frame orientation is only significant with respect to the camera's rotation relative to the optical system. It is irrelevant how the frame is oriented on the sky. That said, if you achieve that orientation by rotating the camera relative to the scope, then you would need a new master flat for each orientation. Brett.

WebThus, we have already solved the two basic problems of the rotation of spirals: flat rotation curves and the Tully-Fisher relation. Therefore, g would depend on M 1/2, or equivalently, on (GM) 1/2. Hence, g=constant (GM) 1/2 R-1. The constant would have the dimensions of the square root of an acceleration and would be a universal constant.

WebThe flat rotation curves are counter to what we see for the distribution of stars and gas in the spiral galaxies.
