In addition to the widely used MIT bag model, we have considered a … WebWe show that the neutron star minimum period of uniform rotation is determined, for causal equations of state, by the maximum value of the relativistic (compactness) parameter … Web1 de ago. de 2024 · If the star is rotating, as the plasma bubble moves radially outwards it is also pushed sideways, just like when you throw a ball while standing on a merry-go-round. (It is called Coriolis effect ). The sideways push will be stronger for plasma bubbles on the equatorial plane, because their velocity is orthogonal to the axis of rotation. how to increase profit margins
