(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..
2008, W. Becker, F, Haberl, J Trümper, 14: Pulsars and Isolated Neutron Stars, Joachim E. Trümper, Günther Hasinger (editors), The Universe in X-Rays, page 193, 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).
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.
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.
Use magnetar when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
