Abstract
This paper proves the existence of variational rotating solutions to the compressible non-isentropic Euler-Poisson equations with prescribed total mass. This extends the result of the isentropic case (see Auchmuty and Beals (1971)) to the non-isentropic case. Compared with the previous result of variational rotating solutions in the non-isentropic case (see Wu (2015)), to keep the constraint of prescribed finite total mass, we establish a new variational structure of the non-isentropic Euler-Poisson equations.
