Abstract

Telah dirumuskan tensor elektromagnetik kontravarian bintang neutron yang berotasi cepat yang diukur oleh pengamat ZAMO (Zero Angular Momentum Observers). Tensor yang diperoleh dalam sistem koordinat bola. Tensor kontravarian digunakan sebagai dasar untuk merumuskan persamaan dinamika medan magnet di bintang neutron yang mengakresi. 

Keywords

tensor elektromagnetik, kontravarian, bintang neutron, berotasi cepat, ZAMO.
