On nonlinear instability of liquid Lane–Emden stars

We establish a dynamical nonlinear instability of liquid Lane–Emden stars in R 3 whose adiabatic exponents take values in [ 1 , 4 3 ) . Our proof relies on a priori estimates for the free boundary problem of a compressible self-gravitating liquid, as well as a quantitative analysis of the competitio...

Zusammenfassung:We establish a dynamical nonlinear instability of liquid Lane–Emden stars in R 3 whose adiabatic exponents take values in [ 1 , 4 3 ) . Our proof relies on a priori estimates for the free boundary problem of a compressible self-gravitating liquid, as well as a quantitative analysis of the competition between the fastest linear growing mode and the source.
