伴星

包含我的研究群在内，天文学家正试著了解MRI如何作用在黑洞周边高热而不透明的吸积盘。在中子星或黑洞伴星上发生吸积的模型，仍应看成是一个有价值的假说。

My group and others are trying to figure out how MRI works in hot , opaque accretion disks around black holes . The model comprising accretion onto a neutron star or black hole companion must still be considered a favored hypothesis .

伴星是物质下陷形成黑洞的一个极好的物质来源。

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

当伴星物质陷落到中子星上时，它就发射出X射线。

As matter falls onto the neutron star , it gives off X-rays .

基于Multi-Agent的伴星自主控制结构研究

Multi-Agent Based Autonomous Control Architectures of Concomitant Satellite

本文在此基础上，讨论具有早型伴星的X射线脉冲星吸积过程中吸积盘与球吸积流的相互作用。

Based on this suggestion we discuss the interaction of disk and spherical accretion streams for X-ray pulsars with early-type companions .

最后提出伴星自主控制的通用Agent体系结构，适用于各种控制结构中的各颗卫星。

At last , a general Agent structure for concomitant satellite is outlined . It can be used to any satellite in any autonomous control architecture .

一个碳氧白矮星可以通过洛希瓣物质交流或者通过星风从其伴星吸积物质，从而增加自身质量，最终由于不稳定的热核燃烧而发生Ia型超新星爆炸。

A carbon-oxygen white dwarf may explode as Type Ia supernova by accreting matter from its company via either Roche lobe overflow or wind .

天文学家长期以来一直怀疑太阳是否有一个小伴星。

Astronomers have long wondered if the Sun has a smaller partner .

航天任务需求对伴星回收问题不仅提出了最省燃料要求，而且提出了最小时间要求。

The diversity of the space missions demands minimization of both fuel and time .

大多数恒星都有一个或更多围绕彼此运动的伴星。

Most stars have one or more of the companion star , borne around one another .

来自我们的看到的星球的物质正被吸引到伴星去。

Matter from the one which we can see is being pulled towards the companion star .

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。

As a companion star orbits its primary , it alternately approaches and recedes from the Earth .

毫秒脉冲星被认为形成于脉冲星从它的伴星中吸取物质时。

A millisecond pulsar is thought to form when the pulsar is siphoning material from a companion star .

如果一颗恒星有一颗伴星，那么当它横越天空运动时，它似乎是摇来摆去。

If a star has a companion , it will seem to wobble as it moves across the sky .

在中子星或黑洞伴星上发生吸积的模型，仍应看成是一个有价值的假说。

The model comprising accretion onto a neutron star or black hole companion must still be considered a favored hypothesis .

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。

The material drawn tidally from the large dying star thus forms a tail that chases the denser companion star from behind .

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。

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

即便如此，科学家也证实了开普勒-452b和几颗系外伴星均位于其恒星的宜居带。

Even so , scientists have confirmed that Kepler-452b is located in its star 's habitable zone , along with several companion exoplanets .

这显示这个天体是一个黑洞，正吞噬这颗超新星或一个双子伴星落下的物质。

This suggests the object is a black hole being fed either by material falling into it from the supernova or a binary companion .

天文学家长期一直怀疑太阳有小伴星。最近，两个独立的小组了端倪。

Astronomers have long wondered if the Sun has a smaller partner . Recently , two independent groups of researchers have found evidence of one .

在一些双星系里，天文学家已经表示这里有一颗看不到的伴星，即我们可以在天空中看到的一颗星球的伙伴。

In some binary systems , astronomers have shown that there is an invisible companion star , a partner to the one which we can see in the sky .

当一个快球靠近你着地时，你得后退一步击球。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。

When a fast ball lands short of you , you have to play back . As a companion star orbits its primary , it alternately approaches and recedes from the Earth .

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。

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 .
