您要查找的是不是：
- unseen companion star 未见伴星
- 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。
- Its companion star,HDE 226868 is a BO super giant with a surface temperature of about 3 1,000 K. 它的伴星HDE226868，质量为超巨大的BO级，表面温度达到31000开尔文摄氏度。
- Its effect on its companion star suggested as early as 1971 that it must be a compact object with a mass too high for it to be a neutron star. 早在1971年，从它对其伴星的影响就认为它肯定是一个被压缩了的星体，有着如此巨大的质量，而不可能是一颗中子星。
- As a companion star orbits its primary, it alternately approaches and recedes from the Earth. 当伴星围绕着主星运转时，它交替地朝着地球或背离地球运转。
- Its companion star, HDE 226868 is a BO super giant with a surface temperature of about 3 1, 000 K. 它的伴星HDE226868，质量为超巨大的bo级，表面温度达到31000开尔文摄氏度。
- Additionally,if the X-ray source is in a binary system,the X-rays will be periodically cut off as the source eclipsed by the companion star. 另外，如果X射线源是一个双星系统，当X射线源被它的伴星所遮挡时，发出的X射线就会周期性地被切断。
- If the neutron star is in a globular cluster, it will perform an erratic dance around the center of the cluster, picking up a companion star which it may later swap for another. 如果这个中子星处于球状星团中，它就会围绕星团中心作不规则的“舞蹈”运动，俘获一个“舞伴”（伴星），而且将来还可能更换它的伴侣。
- Additionally, if the X-ray source is in a binary system, the X-rays will be periodically cut off as the source eclipsed by the companion star. 另外，如果X射线源是一个双星系统，当X射线源被它的伴星所遮挡时，发出的X射线就会周期性地被切断。
- A millisecond pulsar is a supercompact neutron star, whose spin is highly accelerated by mass transferred from a companion star. 毫秒脉冲星是密度极大的中子星，其旋转被从伴星转移来的的物质大大地加快了。
- The material drawn tidally from the large dying star thus forms a tail that chases the denser companion star from behind. 于是，从大的垂死恒星如潮汐般涌出的物质，便形成了一条尾巴，紧追在致密伴星之后。
- It was supposed that Sirius must be affected by a second star, and in 1862 a faint companion star was finally detected by Alvan Clark, and it was named Sirius B. 据猜测天狼星一定受到第二颗星作用影响，而在1862年AlvanClark发现一颗暗淡的伴星，就把它取名为天狼星B。
- It is likely that the companion star in47 Tuc W- a normal star with a mass greater than about an eighth that of the Sun- is a new partner, rather than the companion that spun up the pulsar. 向中子星奔去的物质缓缓地加快着中子星的旋转，如同小孩玩的旋转木马，每当转过来时就推它一把，它就会越转越快。
- More than 60% of the stars in the Milky Way have a companion star around which they orbit. 银河中超过六成的恒星在其运行轨道附近存在伴星。
- This is because the color photos of uncompressed data, accounting for a large photo of the space, and the companion star from the back of the ground is quite a large amount of data. 这是因为彩色照片数据未经压缩，一张照片占相当大的空间，而从伴星传回地面的数据量也相当庞大。
- The oracle bone inscriptions about "a new big star escorts Antares" can be explained as a new big star was "merged into" the Antares.It may be also an outburst of Antares' companion star. 甲骨文“新大星并火”可以解释为新大星“合并”入大火星，可能也是心宿二伴皇的一次爆发。
- While you live in safety, consider unseen dangers. 居安应思危。
- However, it is never an easy task to determine the mass of companion stars in binary systems just by way of spectral analysis. 不过,从光谱分析以决定黑暗的伴星的质量并不是一项容易的观测工作。
- A large unseen orchestra was playing jazz. 一个观众看不到的乐队正在演奏爵士乐。
- In the stage wings, unseen by the audience. 在观众看不到的舞台两侧
