恒星

By using the analogy of star formation in open clusters in NGC 1313 we can infer that stars formed in a similar manner in the Milky Way and so can help us better understand the way the Sun was formed.

通过类比棒状星系NGC 1313中疏散星团的情况，我们可以推测出银河系恒星的类似形成过程，并且能让我们更好地理解太阳的形成。

The star, located some 500 light-years away in the direction of the Ophiuchus constellation, is encircled by a disk of the material from which planets form.

这颗恒星距离我们500光年，蛇夫座方向，被一个将形成行星的物质的圆盘所环绕。

Photographed above is roughly one square degree of the nebula IC 4603 near the bright star Antares toward the constellation of Ophiuchus.

This is also the first planet discovered orbiting a fast-rotating hot star.

这也是首次发现绕一个快速旋转的热恒星运转的行星。

Two stars from the Orion's Belt can be found in the above image.

在上面的影像中，可以发现猎户座腰带上的两颗恒星。

One hypothesisfor the fragmentation and evolution of the knots includes existing gas beingdriven outby a less dense but highly energeticstellar windof the central evolving star.

说明这些物质结分解和演化的假说认为，它们可能是中心星较低密度但较高能量的恒星风所吹送出来的云气。

The author discussed the effect of opacity on stellar evolution and concentrated on the mechanism of triggering blue loop by using Padova stellar model. It shows that extended mixing at the bottom of the convective envelope changed the interior hydrogen profile, which triggers or suppresses blue loop. Laboratory astrophysics, which is a cross subject of astrophysics and plasma physics, combines the demand of accurate data of radiative opacity with the latest advances in high intense lasers to devise the third independent method to study the radiative opacity. On the basis of the comparison between stellar material and laser-produced plasma in terrestrial laboratory, the desirable way to study opacity in laboratory and the brief introduction to the experiments relative to opacity are given.

本论文就开展辐射不透明度实验室研究的背景、内容和意义进行了介绍，并在对实验室的激光等离子体和天体环境下的恒星物质两者差异和相关性的认识基础上，论证了开展辐射不透明度实验室研究的可行性，而且对世界上正在开展的类似研究予以简要介绍，期望可以将天体物理领域对辐射不透明度数据可靠程度的质疑以及对其准确数值的广泛要求，与激光等离子体物理实验的最新进展相结合，推进辐射不透明度实验室研究，为辐射不透明度的研究开拓了继天文观测和理论计算的第三种独立的手段。

However, the emission morphologies produced by incoming particle flow is severely restricted by local pair production in the gap and the absorption of magnetic pair production near the star.

不过，流入粒子流产生的辐射形态受隙中本地对生成和恒星附近的磁对生成的严格的制约。

In 1720 James Bradley carried out a series of experiments attempting to measure stellar parallax .

在1720布拉德利詹姆斯进行了一系列实验，试图衡量恒星视差。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
