SPOTTED: Astronomers discovered a special kind of neutron star for the first time outside of the Milky Way galaxy! ⭐️ Neutron stars like this one spotted by our @nasachandraxray telescope are formed when a massive star runs out of fuel and collapses. The very central region of the star – the core – collapses, crushing together every proton and electron into a neutron. If the core of the collapsing star is between about 1 and 3 solar masses, these newly-created neutrons can stop the collapse, leaving behind a neutron star.Since neutron stars began their existence as stars, they are found scattered throughout the galaxy in the same places where we find stars. And like stars, they can be found by themselves or in binary systems with a companion. Our data suggests that this neutron star is a rare variety that has both a low magnetic field and no stellar companion. Future observations at X-ray, optical, and radio wavelengths will help astronomers learn more about how this neutron star ended up in its current position outside our galaxy.
SPOTTED:天文学家第一次在银河系外发现了一种特殊的中子星! 当我们的@nasachandraxray望远镜发现时,这样的中子星是由一颗巨大的恒星用完燃料并坍塌形成了。恒星的中心区域 - 核心 - 坍塌,将每个质子和电子压缩成一个中子。如果坍缩恒星的核心在大约1到3个太阳质量之间,那么这些新生成的中子可以阻止坍塌,留下一颗中子星。中子星以恒星的形式开始存在,它们被发现分散在整个星系中在我们找到星星的地方夜可以找到它们。和星星一样,它们可以通过它们自己或与同伴一起在二进制系统中找到。我们的数据表明,这颗中子星是一种罕见的品种,同时具有低磁场和无其他恒星的伴侣。未来通过X射线、光学和无线电波段的观测将有助于天文学家更多地了解这颗中子星如何在我们银河系外的当前位置结束。
