Pseudo-isothermal
WebFeb 14, 2024 · We obtain a solution for which this mass density asymptotes approximately to that of the pseudo-isothermal model of dark matter. The resulting gravitational field produces radial acceleration, in the context of a post-Minkowskian approximation, which is negligible at small radius but yields a flat rotation curve at large radius.

Isothermal processes can occur in any kind of system that has some means of regulating the temperature, including highly structured machines, and even living cells. Some parts of the cycles of some heat engines are carried out isothermally (for example, in the Carnot cycle). In the thermodynamic analysis of chemical reactions, it is usual to first analyze what happens under isothermal conditions and then consider the effect of temperature. Phase changes, such as melti… Thought to consist of dark matter, halos have not been observed directly. Their existence is inferred through observations of their effects on the motions of starsand gas in galaxies and gravitational lensing.[3] Dark matter halos play a key role in current models of galaxy formation and evolution.
