中文拼音 [chāozixīng]
超子星
英文
hyperon star-
There is a good chance that this outward diffusion of neutrinos and antineutrinos plays a crucial role in the supernova explosion.
中微子和反中微子的這種向外的散射很可能在超新星爆發中起著關鍵的作用。There is a positive observational and theoretical basis for believing that neutron stars and black holes follow as a result of supernovae.
中子星和黑洞則是超新星的產物,觀測上和理論上的依據使我們相信這一點。In the first seconds after a supernova, a region rich in protons emerges around the dead star ' s core, which has most likely collapsed into a neutron star
在發生超新星爆炸后的最初幾秒內,這個死亡恆星的核心(最可能塌縮形成中子星的地方)周圍,會產生一個富含質子的區域。X - ray flashes had previously been detected from some neutron stars, but they never exceeded the eddington limit by very much
以往天文學家就曾觀測到過從中子星發出來的x射線閃光,但其亮度從來不會超過艾丁頓上限太多。In the case of n132d, the horseshoe shape of the remnant is thought to be due to shock waves from the collision of the supernova ejecta with cool giant gas clouds
在n132d中,遺跡的馬蹄鐵狀外觀據信是因超新星拋出物與巨大的冷分子云相撞所致的。The strong gravitational field of a neutron star provides the answer
中子星的超強引力提供了最佳的解答。The results show that - condensate appears at some baryon densities and makes great effect to the curve of state equation of neutron star ; hyperons - and a exist in neutron star matter at high desities
結果表明, ~ -凝聚將出現在一定的重子密度區間,並對中子星狀態方程曲線有重要的影響;超子~ -和在較高密度也會出現。On the bases of the galaxy evolution theory, we use the therotical chemical evolution model of three zone ( such as halo, thick disk and thin isk ) and multi - phase ( diffuse gas, molecular clouds, stars of both low and high mass, the remnants ). by comparing with the observational constraints, such assurface densities, age - metallicity relation, g - dwarf metallicity distribution in the solar neighbourhood and the correlation between [ a / fe ] and [ fe / h ], supernovae rates, infall rates. the rationality of the model is verified. based on the theory model, we calculate the abundance of neutron capture element
本文正是在銀河系化學演化的基礎上,利用銀河系的三成分( threezone ) (即暈、厚盤和薄盤)多相( multi - phase ) (氣體,分子云,大、小質量恆星以及剩餘物質)的化學演化的理論模型,通過與觀測約束(質量面密度、場星的年齡-金屬豐度關系、太陽附近g矮星金屬含量分佈函數、三成份的特徵量、元素的星系化學演化、超新星的爆炸率、內落速率等)的比較,來檢驗模型的合理性。If the moving fluid in a newborn neutron star also transfers a tenth of its kinetic energy to the magnetic field, then the field would grow stronger than 1015 gauss, which is more than 1, 000 times as strong as the fields of most radio pulsars
如果在新生中子星里的流體,也把10 %的動能轉變成磁場的話,磁場強度會上漲到超過1015高斯,這是大多數無線電波霎所帶磁場強度的1000倍以上。Astronomers knew several examples of neutron stars that lie within supernova remnants
天文學家早就知道好些個位在不同超新星殘骸里的中子星。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。Remaining at the center of the vela supernova remnant is a pulsar, a star as dense as nuclear matter that completely rotates more than ten times in a single second
船帆座超新星爆炸遺骸的中心還存在著一顆脈沖星,它是一顆如原子般緻密的天體,一秒鐘可以自轉十次以上。We now call this kind of super - strong magnetic field neutron stars magnetar, a term coined a few years ago by two theoretical astrophysicists duncan and thompson
天體物理學家鄧肯和湯遜在多年前已把這類具有超級強力磁場的中子星稱為磁星。Topics include : planets, planet formation ; stars, the sun, " normal " stars, star formation ; stellar evolution, supernovae, compact objects ( white dwarfs, neutron stars, and black holes ), plusars, binary x - ray sources ; star clusters, globular and open clusters ; interstellar medium, gas, dust, magnetic fields, cosmic rays ; distance ladder ; galaxies, normal and active galaxies, jets ; gravitational lensing ; large scaling structure ; newtonian cosmology, dynamical expansion and thermal history of the universe ; cosmic microwave background radiation ; big - bang nucleosynthesis

電荷屏蔽對超新星前身星階段電子俘獲的影響By analogy, a neutron star born rotating as fast as or faster than the convective period of 10 milliseconds could develop a widespread, ultrastrong magnetic field
以此類推,在中子星誕生的時候,要是它的自轉速率和10毫秒的對流周期一樣快,甚至更快,就能發展出大區域的超強磁場。Measurement of electron neutrino mass by supernova neutrino bursts
利用超新星爆發測量電子中微子靜止質量The bright source at the center of the image is presumed to be a neutron star created during the supernova
圖片中心的明亮輻射源據信是超新星爆發過程中產生的中子星。Neutron superfluid vortex in neutron stars and its astronomical effects peng qiuhe
中子星內中子超流渦旋及其天文效應[彭秋和]Unlike the rapidly rotating neutron stars in the crab nebula and vela supernova remnants that are surrounded by dynamic magnetized clouds of electrons called pulsar wind nebulas, this neutron star is quiet, faint, and so far shows no evidence for pulsed radiation
與蟹狀星雲和船帆座超新星遺跡中被磁化電子云(脈沖星風星雲)環繞的高速自轉中子星不同,這顆中子星安靜而虛弱,目前為止,沒有顯示脈沖輻射的跡象。分享友人
