磁星 Magnetar

(重定向自Magnetars)
画家笔下的磁星想像图

磁星」(Magnetar)是中子星的一种,它们均拥有极强的磁场,透过其产生的衰变,使之能源源不绝地发布高能量电磁辐射,以X射线及伽玛射线为主。磁星的理论于1992年由科学家罗伯特·邓肯(Robert Duncan)及克里斯托佛·汤普森(Christopher Thompson)首先提出,在其后几年间,这个假设得到广泛接纳,去解释软伽玛射线复发源(soft gamma repeater)及不规则X射线脉冲星(anomalous X-ray pulsar)等可观测天体。

Magnetar 磁星

Artist's conception of a magnetar, with magnetic field lines.
Artist's conception of a powerful magnetar in a star cluster.
Magnetar SGR 1900+14 is in the exact center of the image, which shows a surrounding ring of gas seven light-years across in infrared light, as seen by the Spitzer Space Telescope. The magnetar itself is not visible at this wavelength, but it has been seen in X-ray light.
Artist's impression of a gamma-ray burst and supernova powered by a magnetar.[15]

A magnetar is a type of neutron star with an extremely powerful magnetic field. The magnetic field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays. The theory regarding these objects was proposed by Robert Duncan and Christopher Thompson in 1992, but the first recorded burst of gamma rays thought to have been from a magnetar had been detected on March 5, 1979. During the following decade, the magnetar hypothesis has become widely accepted as a likely explanation for soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs).
