Abstract

Struktur bintang neutron statis dan terdeformasi dapat dikonstruksi melalui persamaan TOV termodifikasi parameter γ dan persamaan TOV termodifikasi koordinat oblate spheroid. Persamaan TOV termodifikasi parameter γ diperoleh melalui parameterisasi komponen jari-jari polar sedangkan persamaan TOV termodifikasi koordinat oblate spheroid diperoleh mela- lui transformasi koordinat oblate spheroid. Pada tugas akhir ini, digunakan persamaan keadaan gas fermi neutron, proton, dan elektron yang tidak berinteraksi. Solusi yang diperoleh dari persamaan TOV termodifikasi ini dapat menggambarkan struktur bintang neutron statis dan terdeformasi. ============================================================ ============================================================ The stellar structure of static and deformed neutron stars are constructed from both modified TOV equation by γ parameter and modified TOV equation by oblate spheroid coordinate. The modified TOV equation by γ parameter is obtained from parameterization of polar radius component. The modified TOV equation by oblate spheroid coordinate is obtained from oblate spheroid coordinate transformation. In this work, we employ ideal fermi gas of neutron, proton, and electron as an equation of state. The solutions obtained from these modified TOV equation describe the structure of static and deformed neutron star.
