... mysterious pulses that are being emitted by an extremely magnetic star. The magnetic star, a magnetar, emits the pulses as very high energy X-rays. The astronomers made their observations using the ...
... scientists might have detected an unexpected new sub-category of astronomical objects. It appears to be a magnetar with bursts in the visible part of the spectrum, in contrast to the X-ray and gamma ...
... 100 trillion times stronger than Earth's, a magnetar placed half the moon's distance would ... anomalous X-ray pulsars -- are thought to be magnetars. But, all told, astronomers know of only 15 examples ...

Some scientists have noted that magnetars should be evolving towards a pleasant retirement as their magnetic fields decay, but no ...
... rotation rate of 2.6 seconds, this magnetar must be old enough to have slowed down. ... exploded star, possibly the same one that created the magnetar. "These usually fade to invisibility after a few tens ...
At 1014 gauss, atoms are compressed into tiny needles whose widths are only 1% of their lengths. X-ray photons readily undergo an exotic process where they change into matter and anti-matter ...
