The normal way of determining the magnetic field of a magnetar is to measure the rate at which the spin is declining.
It is one of about two dozen neutron stars called magnetars, which have very powerful magnetic fields and occasionally produce high-energy explosions or pulses.
That is why the discovery of a wind nebula - which is created around a pulsar when its fast rotation and strong magnetic field interact to accelerate electrons and other particles to very high energies - around a magnetar assumes special importance.
The galactic center magnetar is still cooling off two years after its initial outburst, its X-rays steadily declining in intensity.
We have found that SGR 0418 has a much lower surface magnetic field than any other magnetar," said Nanda Rea of the Institute of Space Science in Barcelona, Spain.
Although the team may have uncovered a new kind of neutron star, theorist Robert Duncan of the University of Texas at Austin says that "a more reliable and conservative interpretation" is that the researchers have detected elderly rotating neutron stars--either radio pulsars or magnetars, which have the strongest known magnetic fields of any star.
9 million appraised shares were held by affiliates of Magnetar Capital.
Thornton and his colleagues consider a few ideas in their July 5th Science paper, but their favorite is that the bursts are giant flares from a highly magnetized neutron star called a magnetar.
The recently discovered star appears to be a hybrid of these two stellar breeds: the spinning stellar skeleton appears as a pulsar while hiding an intense internal magnetic field much like a magnetar.
Investment management firm Magnetar Capital said on Sunday that it has signed a definitive agreement to sell interests in metallurgical and steam coal company International Resource Partners LP (IRP) ro James River Coal Company (Nasdaq:JRCC) for USD475m in cash.
2 percent ownership interest in Magnetar MLP Investment, LP (Magnetar MLP) for net consideration of $9.
By tracing the outburst to a magnetar, the rare type of star with the strongest magnetic field known, the scientists may be able to account for a puzzling group of extremely short-lived gamma-ray bursts from distant galaxies.
