neutron star 【天文學】中子星。

neutropenia

The main difference between neutron stars and black holes lies in the fact that neutron star has a solid surface whereas the black hole does not 中子星和黑洞的重要不同之處,是中子星有一個固體表面,而黑洞則沒有。

One ramification of our calculations is that radio pulsars are neutron stars in which the large - scale dynamo has failed to operate 從我們的計算中,還可以附帶得到一點:無線電波霎正是無法形成大尺度發電機的中子星。

As the matter falls toward the neutron star or black hole , it is heated by frictional forces to tens of millions of degrees , and produces x - rays 當物質落向中子星或黑洞時,會被摩擦力加熱到幾百萬度,并產生x射線。

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,于是這顆中子星就向成為毫秒脈沖星邁出了關鍵的第二步。

The above discussion concentrates on the single star system . there are many interesting phenomena in a neutron star binary system 以上的討論都是基于單星系統的,其實宇宙中存在不少有趣的中子星雙星系統。

This requires even more detectors because these waves are even weaker than the waves from binary stars and neutron stars 這將需要更多的探測器,因為與雙星和中子星產生的引力波相比,這些引力波還要更弱。

To adapt the wormhole for time travel , one of its mouths could be towed to a neutron star and placed close to its surface 要改造蠹孔以進行時光之旅,可以把它的一個開口拖往中子星,并安放在其表面附近。

Searching for x - ray sources in the sky becomes the most important ways to locate neutron stars and black holes among binary system 觀測星空中的x射線源成為尋找雙星系統中的中子星或黑洞的最重要方法。

Moreover , most astronomers believed in the above magnetic field figures for neutron stars until recently . in may 1998 , kouveliotou 一九九八年五月,高維利奧圖發現了sgr1806 - 20這顆異常奇特的中子星。

If the pulsar with submillisecond period would exist , it should be a strange star rather than a neutron star 如果一顆周期少于一毫秒的脈沖星真的存在的話,它便很可能會是一顆奇異星而不是中子星。

Since the gravitational field on the surface is very strong , no hills or mountains can be formed on a neutron star 由于引力場實在太強大,任何山脈高山皆會被引力蕩平,所以中子星的表面十分光滑。

G . in fact , neutron star magnetic field is the strongest amongst all stars we know of to date 高斯。事實上,中子星的磁場是所有已知恒星之中最強的,然而,大部分天文學家到最近才接受這數據。

The periodic pulsation and low energy gamma - ray outbursts are two typical characteristics of a young energetic neutron stars 周期脈沖和低能量伽瑪射線的發放都是年輕中子星所具備的特質。

Frequent space museum visitors should know that neutron star is one of the possible final products of stellar evolution 經常參觀太空館的人該知道,中子星是恒星演化至末期的結果之一。

Identifying the source as a neutron star did not solve the puzzle ; on the contrary , it merely heightened the mystery 確認光源是顆中子星,并沒有把謎團解開,反而讓問題變得更神秘。

Due to the existence of high viscosity in strange matter , strange stars can reach much shorter period than neutron stars 由于奇異星有很高的粘度,它的自轉周期會比中子星短得多。

Supernovae remnants can leave behind pulsars or spinning neutron stars that may produce gravitational waves 超新星遺跡中可能還存留有脈沖星或自旋中子星,而這些都會產生引力波。

The former happen when an old neutron star spirals to its death in a preexisting black hole 在一顆老邁的中子星漸漸死亡,落入一個業已存在的黑洞中時,前一種情況也就發生了。

In this model , neutron star ' s maximum mass is 1 . 12ms , with corresponding radius about 8km 在我們的模型中,中子星最大質量極限為1 . 12ms ( ms為太陽質量) ,對應半徑約為8km 。
