Περίληψη:
We study the oscillation spectrum of neutron stars containing both
ordinary matter and dark energy in different proportions. Within the
model we consider, the equilibrium configurations are numerically
constructed and the results show that the properties of the mixed
neuron-dark-energy star can differ significantly when the amount of
dark energy in the stars is varied. The oscillations of the mixed
neuron-dark-energy stars are studied in the Cowling approximation. As
a result we find that the frequencies of the fundamental mode and the
higher overtones are strongly affected by the dark energy content.
