Abstract
Stars are all rotating but some more than others… Rotation is fast when you cannot ignore it, whatever the problem you are considering. Practically, I consider that if the centrifugal flattening of a star exceeds 5%, it is rapidly rotating. The Sun’s flattening is 0.001%, thus very very small: it is a slowly rotating star.
In this talk I will therefore focus on stars that spin about a hundred times faster than the Sun. I’ll present the many questions, and their first answers, emerging as we seek to understand how rotation shapes stellar evolution and stellar seismology.
Series This talk is part of the Fluid Mechanics (DAMTP) series.
