有研究团队发现中子星散发出罕见的红外光,这是一种前所未见的现象。
据NASA网站报导,巨大的恒星在生命的末期,经由重力坍缩发生超新星爆炸之后,可能变成中子星。这种密集度很大的残骸又称为脉冲星(pulsar),因其旋转速度极快,而旋转所产生的无线电波等各种辐射则可能以一明一灭的方式对外发送。
尽管科学家通常以无线电波和X射线等高能量辐射线研究中子星,但本次的研究证实,有关中子星的讯息也可以透过红外光来取得。
由土耳其和美国多所大学的科学家所组成的研究团队观测到,一颗名叫RX J0806.4-4123的中子星,其四周有红外光散射的区域,其大小约有200个天文单位(约299亿公里)

This illustration shows a neutron star (RX J0806.4-4123) with a disk of warm dust that produces an infrared signature as detected by NASA's Hubble Space Telescope. The disk wasn't directly photographed, but one way to explain the data is by hypothesizing a disk structure that could be 18 billion miles across. The disk would be made up of material falling back onto the neutron star after the supernova explosion that created the stellar remnant.
