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 on…
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…
Nonradial stability of expanding Goldreich-Weber stars
Mahir Hadžić, Juhi Jang, King Ming Lam
Goldreich-Weber solutions constitute a finite-parameter of expanding and collapsing solutions to the mass-critical Euler-Poisson system. Two subclasses of this family correspond to…
Linear Stability of liquid Lane-Emden stars
King Ming Lam
We establish various qualitative properties of liquid Lane-Emden stars in , including bounds for its density profile and radius . Using them we prove that agai…
