超新星

So the calcium that is in your bones and the iron that is in your blood probably came from supernovae that exploded before the sun formed.

所以，你骨骼里的钙和你血液里的铁很可能来源于太阳系形成前超新星的爆炸。

Pinpointing supernovae in the faraway universe is similar to watching fireflies in your back yard.

在遥远的宇宙中精确定位超新星就像在你的后院中观察萤火虫。

Pair'.'' of supernovae explosions occurred near Earth.

时候'。''，地球附近的两颗超新星发生了爆炸。

Red supergiants are the most common stars that end their lives as supernovae.

以超新星形式结束自己生命的最常见的星星类型就是红超巨星。

Supernovae also come from larger, more developed galaxies than do the gamma-ray bursts.

超新星也来自于更大更成熟的星系的星系。

Not just any old relics, neutron stars are the leftover cores of huge stars that exploded in supernovae.

和一般残骸不同，中子星是以超新星方式爆炸的巨大星球的残余核心部分。

So the calcium that is in your bones and the iron that is in your blood probably came from supernovae that exploded before the sun formed.

所以你骨骼里面的钙和血液里面的铁都很可能来自超新星，其在太阳形成前爆炸。

Models of element synthesis during the supernova explosions predict that the abundance ratios of actinide s with respect to other stable elements heavier than iron are very sensitive to the environment of the explosion, such as the entropy and the ratios o

模型元素的合成，在超新星爆炸预言的丰度比锕对于其他稳定更重的元素，比铁很敏感，对环境造成的爆炸，如熵和比例的质子，中子和电子。

Major advances have been made in the last a few years, including the discovery of fading X-ray, optical and radio afterglows of GRBs, the identification of host galaxies at cosmological distances, and evidence showing that many GRBs are associated with star-forming regions of the host galaxies and possibly a peculiar type of supernova.

过去几年里γ暴的研究取得了重大突破，包括发现了变暗的X射线、光学和射电余辉，探测到位于宇宙学距离的寄主星系，发现γ暴与恒星形成区成协、甚至可能与超新星关联的证据等等。

The researches include the dense medium effect on the evolution of afterglows, constraints on the physical parameters of GRBs, the origin of the energetic gamma-ray emission from GRBs, the inverse Compton spectra in the very early afterglows, and energy source mechanism of the supernova-GRB connection.

研究工作主要包括：γ暴周围环境对余辉演化的影响、γ暴的物理参数的限制、极高能γ射线的起源、极早期外激波区域的逆康普顿散射光谱与观测效应以及γ暴与超新星关联的理论解释。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
