An x - ray binary system has been formed, and the neutron star has made the crucial second step toward becoming a millisecond pulsar
射線雙星就這樣形成了,於是這顆中子星就向成為毫秒脈沖星邁出了關鍵的第二步。 -
They suggest that these similarities between a known millisecond pulsar and a known x - ray binary provide the long - sought link between these types of objects
他們認為,一個已知的毫秒脈沖星與一個已知的x射線雙星之間的這種相似性,為我們提示了這兩類天體間長期未知的內在聯系。 -
Most astronomers accept the binary spin - up scenario for creating millisecond pulsars because they have observed neutron stars speeding up in x - ray binary systems, and almost all radio millisecond pulsars are observed to be in binary systems
多數天文家接受這個假想的模式,因為他們已經在x射線雙星系統中觀測到了中子星的加速現象,而且幾乎所有的毫秒脈沖星都被發現時處于雙星系統中。 -
It links a millisecond pulsar with many of the properties of an x - ray binary, to j1808, an x - ray binary that behaves in many ways like a millisecond pulsar, thus providing a strong chain of evidence to support the theory
然而直到目前,決定性的證據還未獲得,因為介於第一和第二步之間的過渡天體還幾乎不為人所知。 -
Such a process can take place in the low mass x - ray binary systems where the mass transfer from the companion to the neutron star can be larger than 0. 5 solar masses. if the neutron star in the low mass x - ray binary accretes the matter, the central densities can reach to a state that strange - matter seeds are formed in the interiors of the star
在這個系統內,中子星可能會吞噬超過0 . 5個太陽質量的伴星物質,當中子星吸收了這些物質后,中心的密度會增加至足以產生奇異物質種子,這些種子會開始吞噬四周的中子物質,釋放出大量中微子和反中微子,令星體冷卻。
