Abstract :
The effect of cosmological parameter on rotation of boson star oscillations is studied. The study found that the amplitude of rotation of boson star ground state and excited state decreased under the correction of cosmological constant in the Lagrangian density of Boson star.

Key-Words / Index Term :
