A turning point principle for liquid Lane-Emden stars
King Ming Lam
Upon fixing the adiabatic index, the spherically symmetric liquid Lane-Emden stars governed by the Euler-Poisson system with a "stiffened gas" equation of state form a…

Nonradial linear stability of liquid Lane-Emden stars
King Ming Lam
The classical model of a star is the Lane-Emden star with dynamics governed by the Euler-Poisson equations. We consider the case of a liquid star with a "stiffened gas" equation of…
