Abstract

Tesis ini mengkaji model bintang boson Einstein-Klein-Gordon yang terkopel dengan muatan sumber dan materi. Konfigurasi ini dibangun dari medan skalar riil dengan sumber ditambah materi yang direpresentasikan oleh fluida ideal. Selain itu, diasumsikan sumber memiliki kesbandingan dengan densitas massa-energi fluida ideal. Keberadaa sumber dan materi terebut dapat menghasilkan solusi yang statik pada medan skalar riil. Solusi diperoleh dengan profil medan yang terlokalisasi. Potensial kuadratik menjadi potensial yang dominan dalam menentukan perilaku solusi, sedangkan potensial kuartik berperan dalam menentukan lokalitas solusi. Adapun potensial Φ^4 dan Φ^6 juga berperan dalam meningkatkan masssa total sistem.

In this thesis, we studied Einstein-Klein-Gordon boson star model coupled to source and matter. This configuration was build from a real scalar field with source plus matter that represented by perfect fluid. In addition, it had been Imposed that the source had proportionality with perfect fluid mass-energy density. The existence of this source and matter produced static solution to the real scalar field. Solutions were obtained with localized field profiles. The quadratic potential became the dominant potential in determining the behavior of the solution, while the quartic potential played a role in determining the locality of the solution. The Φ^4 and Φ^6 potential also played a role in increasing the total mass of the system.
