Respuesta :
If a spinning star gets larger in diameter its rotation rate is decreases.
As the radius of a spinning star decreases, some of its rotational inertia is lost, which results in a rise in rotational speed owing to the conservation of angular momentum. Because stars gradually slow down over time, much like a top spinning on a table, a star's spin rate depends on its age. The mass of a star also influences its spin; astronomers have discovered that larger, heavier stars have a tendency to spin more quickly than smaller, lighter ones. As the radius of a rotating star decreases, some of its rotational inertia is lost, which results in a rise in rotational speed due to the conservation of angular momentum.
