These uniformly rotating cores are often unstable to gravitational collapse.

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. Web16 de nov. de 1999 · We adopt an adiabatic equation of state with and focus on uniformly rotating stars. We find that the onset of dynamical instability along mass-shedding sequences nearly coincides with the onset of secular instability. Unstable stars collapse to rotating black holes within about one rotation period.
