TY - JOUR ID - 43241 AU - Hledík, Stanislav - Mrázová, Kristina - Stuchlík, Zdeněk PY - 2008 TI - Dynamical stability of fluid spheres in spacetimes with a nonzero cosmological constant PB - World Scientific CY - Singapore SN - 9789812834263 KW - Perfect fluid configurations, Cosmological constant, Dynamical stability N2 - The Sturm-Liouville eigenvalue equation for eigenmodes of the radial oscillations is determined for spherically symmetric perfect fluid configurations in spacetimes with a nonzero cosmological constant and applied in the cases of configurations with uniform distribution of energy density and polytropic spheres. It is shown that a repulsive cosmological constant rises the critical adiabatic index and decreases the critical radius under which the dynamical instability occurs. ER -
