伴星

Here we report interferometric images that show the eclipsing body moving in front of the F star. The body is an opaque disk and appears tilted as predicted.

我们在此报告：根据干涉图像测定，掩食伴星已经移到主星前，它带有尘埃气体盘，与先前预计一样是带倾角的。

A companion star is a perfect source of infalling material for a black hole.

伴星是物质下陷形成黑洞的一个极好的物质来源。

Theory predicts that a white dwarf star will explode when infalling matter from a companion star increases the mass of the white dwarf beyond a critical mass limit, known as the Chandrasekhar limit.

理论预言，当来自伴星的物质让白矮星的质量增加到了临界质量极限即钱德拉塞卡极限时，白矮星就会爆发。

The region is in the Large Magellanic Cloud, a satellite of our Milky Way galaxy. It is a fascinating laboratory for observing star-formation regions and their evolution.

这个区域位于我们银河系的伴星系——大麦哲伦云，这个是观察恒星诞生、演化的迷人实验室。

Because the core mass of the AGB star is remarkably large at low metallicity.

对于AGB星初始质量小于3M_☉且初始轨道距离较远的双星系统，白矮星不能从受污染的星上吸积充足的物质，因此不能形成AIC，其伴星只受到AGB前身星的污染，从而形成s-过程元素超丰的星。

Astronomers don't know exactly what role the companion has played in the evolution of Eta Carinae, or what role it will play in its future.

天文学家不是确切的知道伴星在Eta Carinae的进化中是扮演怎样的一个角色，或者在其自己的未来中扮演什么角色。

Recent work implies that the system consists of a low-mass (2.2M⊙–3.3M⊙) visible F-type star, with a disk at 550K that enshrouds a single B5V-type star.

最新的研究认为：双星系统的主星为2.2~3.3个太阳质量的F型星，伴星则是包裹在550K尘埃气体盘中的B5V型星。

The companion galaxy's pull would be inducing extra starbirth by compressing gas, jump-starting the process by which stars form.

伴星系的拉力会以压缩气体的方式引发额外的产星活动，气体的压缩正是恒星形成过程的开端。

By the time that material from the dying star reaches the companion, the latter has scooted well ahead in its orbit.

当来自垂死恒星的物质到达伴星之前，后者早就在轨道上往前急冲了一段距离。

Also known as Messier 51a, M51a, or NGC 5194, the Whirlpool Galaxy is an interacting grand-design spiral galaxy located at a distance of approximately 23 million light-years in the constellation Canes Venatici.

漩涡状星系又被称为&梅赛耶51a&，&M51a&或&NGC 5194&，与的地球距离为2300万光年，位于北天的猎犬座，是一个庞大的，与它的伴星系共存的螺旋状星系。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
