Sentences with phrase «dynamical models»

The phrase "dynamical models" refers to mathematical or computational representations of how things or systems change over time. It involves studying and predicting the behavior and evolution of these things or systems by considering their interactions, forces, or variables that affect their states as time progresses.

Four years later, another team of astronomers using the 2.5 - meter Isaac Newton Telescope at Roque de los Muchachos Observatory on La Palma (and relying on evidence supplied by their own dynamical models of Sagittarius and on preliminary results from the international Sloan Digital Sky Survey team) announced that they had found an excess of young stars belonging to a stellar system located at 183,000 ly (56,000 pc) from the center of the Milky Way.
The formation of large - scale mills in the southern oceans is an interesting phenomenon in this respect, although presumably oceanic computational fluid dynamical models may not necessarily reveal such complex vortex - type phenomena.
