Magnetar
Magnetar ialah jenis bintang neutron dengan medan magnet yang sangat kuat (∼109 sehingga 1011 T, ∼1013 sampai 1015 G).[1] Peluruhan medan magnet mempengaruhi pelepasan tenaga-tinggi radiasi elektromagnetik, terutama sinar-X dan sinar gama.[2] Teori tentang objek ini diusulkan oleh Robert Duncan dan Christopher Thompson pada tahun 1992, tetapi letusan sinar gama yang pertama kali tercatat berasal dari sebuah magnetar telah dikesan pada 5 Mac 1979. Selama dekad berikutnya, hipotesis magnetar diterima secara luas sebagai penjelasan yang mungkin untuk pengulangan gama lembut (SGRs) dan anomali pulsar sinar-X (AXPs).
