Walter Strauss: Continua of Rotating Stars

I will present a survey of a mathematical approach to constructing rotating stars that is joint work with Yilun (Allen) Wu.   The star is modeled as a compressible fluid satisfying Euler equations subject only to steady rotation and gravity. Under certain conditions there exists a large family of solutions on which the supports of the stars become unbounded. The stars have a fixed mass and they rotate around a fixed axis at a speed that varies along the family.  I will also mention several other models.  One of these, joint with Yilun Wu and Juhi Jang, permits the entropy to be variable.
