magnetar (plural magnetars)

1. (astronomy) A neutron star or pulsar with an extremely powerful magnetic field, especially those on which starquakes occur, thought to be the source of some gamma-ray bursts.

     This signal could be detected with Advanced LIGO-class detectors up to the distance of the Virgo cluster, where ≥ 1 yr⁻¹ magnetars are expected to form.

     The radio-silent neutron stars include anomalous X-ray pulsars (AXPs), soft gamma-ray repeaters (SGRs), and “quiescent” neutron star candidates in SNRs. There is growing evidence that AXPs and SGRs are indeed magnetars (see [109] for a review).

Torres, editors, High-Energy Emission from Pulsars and Their Systems: Proceedings of the First Session of the Sant Cugat Forum on Astrophysics, page 576:

     One of most mysterious feature[s] of magnetars is their X-ray luminosities, which always exceed the rotational energy loss. Thus, the energy source of the radiation of magnetars is a mysterious question.
