Magnetar vs Null - What's the difference?
magnetar | null |
(star): 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 burst, gamma-ray bursts.

is that magnetar is magnetar while null is zero, nil; the cardinal number before einn.magnetar

- 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).

- 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.
