n.
A neutron star with a very strong magnetic field. Magnetars are the proposed sources of observed gamma-ray bursts.

[magnet(o)- + -ar (as in pulsar, quasar).]

magnetar

(ˈmæɡnɪtɑː)
n
(Celestial Objects) a type of neutron star that has a very intense magnetic field, over 1000 times greater than that of a pulsar
[C20: from magnet(ic) (st)ar, on the model of quasar]

The internal field is many times stronger than its external magnetic field, leading to its entry into the new class of 'low-field magnetars'.

Theory suggests that when a magnetar's twisted field snaps, the star's crust rips apart, unleashing gamma rays.
New data from these powerful telescopes later confirmed that 1E 1613 has the properties of a magnetar 6 a type of neutron star with an extremely powerful magnetic field 6 making it only the 30th known one.
In the magnetar model, the star has already gone supernova when the real fireworks begin.
Astronomers had identified five neutron stars, known as soft gamma-ray repeaters, as magnetars (SN: 9/12/98, p.
"If the process here is similar, then about 10 percent of the magnetar's rotational energy loss is powering the nebula's glow, which would be the highest efficiency ever measured in such a system."
Magnetar Global Event Driven Master Fund Ltd., (147) one of Delaware's most recent appraisal decisions, the court again acted in accordance with this trend, chastising the Chancery Court for disregarding the merger price altogether and using its own DCF model to value the shares instead.
Because of the extremely short, repeated bursts, the source was thought to be a kind of neutron star: either a pulsar (which spins very fast) or a magnetar (which spins but also has an extra strong magnetic field).
In this section, we are going to construct the wave function of the charged bosons, considered as test particles evolving in the crust of a relativistic magnetar. The complex scalar field of mass [mu], minimally coupled to gravity, is described by the SO(3,1) x U(1) gauge covariant Klein-Gordon equation
Still, Hessels believes that the culprit must be a young stellar remnant--maybe a rapidly spinning magnetar (a strongly magnetized neutron star).
