-
The total gravity force on the star from the stars enclosed by its circular orbit can be treated as if they are concentrated at the center.
对于一个离中心为 r 的恒星来讲,来自轨道内的恒星的引力与把它们集中在星系中心的一样,来自轨道外的恒星的引力合力为零。

The results show that the turbulent pressure can be 30 percent of the total pressure in the region closed to the surface of a AGB star with 7M〓 and has an important influence on the inner structure and evolution.
结果表明,对于7M〓恒星,在红巨星及AGB阶段,湍流压可以达到总压强的30%,并且对恒星的结构产生重要影响,对于2.8M〓恒星,在红巨星及AGB阶段影响较小。

Seen in silhouette near the top of the view are small, dark clouds of obscuring cosmic dust.
影像顶端的这些既小又暗的宇宙尘埃云,是以发现者命名的谢克瑞云球(Thackeray's Globules),它们也是未来新恒星可能成形的区域,不幸的是,附近年轻恒星所发出的高能量辐射,很可能也正在侵蚀它们,因此它们未来是否能形成恒星之命运未卜。

As the Earth's rotation axis in space there is precession and nutation, by the effects of precession and nutation is called true sidereal day sidereal day, excluding the impact of nutation, only affected by the precession of the sidereal day sidereal day is called flat.
由于地球自转轴在空间存在岁差和章动,受岁差和章动影响的恒星日称为真恒星日,扣除章动的影响,仅受岁差影响的恒星日称为平恒星日。

Our abundance analysis, which followed standard prescriptions for stellar models, spectral synthesis code and stellar parameter determination12, confirm the peculiar behaviour of Li in the effective temperature range 5600–5900 K for the 30 planet-bearing stars with respect to the 103 stars without planets in the comparison sample.
通过对恒星模型、光谱合成辨认、以及恒星参数的确认(参考文献12)等大量分析后,在有效温度介于5600~~5900K的30颗"有行星"恒星与103颗"无行星"恒星的实验对照组中,我们可以确定锂元素的确表现出独特的性质。

From the distribution of rotation period and convection parameter of M type stars, stellar chromospheric activity of M type stars depart from the anticipation of a.
对于A—早F型主序恒星的色球活动水平也随自转周期呈线性下降趋势,随Rossby数却呈上升趋势。A—早F型主序恒星的自转周期和恒星对流区的随色指数的分布明显地影响着这些恒星的色球活动行为。
-
For A-early F type MS stars, stellar chromospheric activity decrease with stellar rotation period, but increase with Rossby number; For M type MS stars, stellar chromospheric activity increase with stellar rotation period and Rossby number, and stellar chromospheric activity reach saturation at large color index; For the MS stars between mid-F to M type, stellar chromospheric activity decrease with stellar rotation period and Rossby number.
在第五章中,我们采用不同的磁活动指数研究了晚型恒星磁活动与恒星自转参量(自转周期、Rossby数)、磁活动与恒星色指数以及恒星磁活动指数之间的相关性。大样本分析显示晚型主序恒星的色球活动与恒星自转参量的研究晚型主序恒星的色球活动与恒星自转参量间的关系表现出对恒星光谱型的依赖。
-
These so-called dark stars, named for the song "Dark Star" by the Grateful Dead , would contain mostly normal matter, in the form of hydrogen and helium molecules, but would be vastly larger (about 400 to 200,000 times wider) and "fluffier" than the sun and other stars.
这些所谓的暗恒星,是根据&感恩而死&乐队创作的歌曲《暗恒星》命名的。暗恒星中所包含的主要是普通物质,以氢分子和氦分子的形式而存在。但是暗恒星比太阳和其他恒星要大得多(大400倍至20万倍),密度也要低得多。
-
Employed by consortia that operate global networks of telescopes (the Optical Gravitational Lensing Experiment and Microlensing Observations in Astrophysics), microlensing allows continuous monitoring for subtle brightening of far-distant stars as a relatively nearby star passes in front of them.
天文协会启动全球的望远镜网络,利用微引力透镜效应,可以连续监视诸多远距离恒星微妙的亮度增加情况。当一颗较近的恒星在遥远的恒星前面经过时,较远恒星的亮度就会有所增加。
-
Dr. Yoshida's simulation also shows that the protostar would likely evolve into a massive star capable of synthesizing heavy elements, not just in later generations of stars, but soon after the Big Bang.
另外,Yoshida博士的模拟也揭示了原恒星演化成大质量恒星的可能性,在大质量恒星中一些较重的元素得以合成,模拟背景不是原恒星的后续演化,而是在大爆炸之后。

sidereal day:恒星日
天文学家计算这种与太阳不同的恒星出没的时间是用的一种"恒星日"(sidereal day),这一日之长正好等于一颗星(或春分点)两次经过子午圈之间的时间. 天文学家又将一恒星日分为24恒星时,再照常分为分秒. 他们又用一种比普通时钟每天快3分56秒的恒星时钟来计算恒星时.
