恒星时

Lawrence martyr , 10 august : the monthly recurrence known as the new moon with the old moon in her arms : the posited influence of celestial on human bodies : the appearance of a star 1st magnitude of exceeding brilliancy dominating by night and day a new luminous sun generated by the collision and amalgamation in incandescence of two nonluminous exsuns about the period of the birth of william shakespeare over delta in the recumbent neversetting constellation of cassiopeia and of a star 2nd magnitude of similar origin but lesser brilliancy which had appeared in and disappeared from the constellation of the corona septentrionalis about the period of the birth of leopold bloom and of other stars of presumably similar origin which had effectively or presumably appeared in and disappeared from the constellation of andromeda about the period of the birth of stephen dedalus , and in and from the constellation of auriga some years after the birth and death of rudolph bloom , junior , and in and from other constellations some years before or after the birth or death of other persons : the attendant phenomena of eclipses , solar and lunar , from immersion to emersion , abatement of wind , transit of shadow , taciturnity of winged creatures , emergence of nocturnal or crepuscular animals , persistence of infernal light , obscurity of terrestrial waters , pallor of human beings

This paper can infer time of GPS satellite clock that there is a periodic variation of 12 sidereal hour, and GPS satellite orbit period is just 12 sidereal hour, no doubt, it be designed for to check up time.

本理论可以推导出GPS卫星钟的快慢，有12恒星时的周期变化，而GPS卫星轨道周期正好为12恒星时，极可能是为了方便校对时间而设计的。

For example, since the earth to the base, relative to the sun to measure time to get the sun when the time is measured relative to the stars, known as the sidereal time, to atomic transition frequency as a benchmark time for the system is called atomic time.

例如，以地球自转为基准，相对于太阳来计量时间得到的是太阳时，相对于恒星来计量时间，称为恒星时，以原子的跃迁频率为基准的时间系统称为原子时。

We've been observing a sunlike star called 55 Cancri, star 55 in the constellation Cancer, for 19 years, and we watch the wobble of this star as it's yanked on by the planets orbiting it.

&我们一直观察这名为&55 Cancri类太阳恒星19年了。55号恒星是在巨蟹星座中。当它吸引行星围着它转时，我们观察它移动的轨迹。

We've been observing a sunlike star called 55 Cancri, star 55 in the constellation Cancer, for 19 years, and we watch the wobble of this star as it's yanked on by the planets orbiting it.

我们19年来一直在观察一个类似太阳的恒星叫55号巨蟹星，是巨蟹星座里的第55号恒星。当它被环绕它的行星牵引时，我们发现它有些颤抖。

At the dimmest part of a Cepheid's cycle, the ionized gas in the outer layers of the star is opaque, and so is heated by the star's radiation, and due to the increased temperature, begins to expand.

在造父变星的一个光变周期开始时，恒星最暗，此时其外层电离气体是相对不透明的，因此会吸收恒星的辐射而升温，并开始向外膨胀。

As they move into their near-star orbits, hot Jupiters could be playing violent games of planetary billiards that produce Earthlike planets, he says.

在它们靠近恒星时，它们可能会发生可怕的碰撞并产生类似地球的行星。

"If you look at how the spectrum of the star changes when the planet transits across it, you can work out which way the planet is travelling," Professor Hellier added.

英国科学家利用一系列观测恒星的照相机进行观察恒星发出的光线粒子时，这颗行星在他们面前掠过，这才发现了这颗行星。

Planetary nebulae are the spectacular final phase in the life of Sun-like stars, when the star ejects its outer layers into the surrounding space.

行星状星云是像太阳这样的恒星最后的辉煌，当恒星进入生命晚期时，它会把外层大气抛到周围的太空中。

For example, if the working wavelength range is reduced from 300~1100 nm to 400~800 nm, the single star position errors will be 0.0422"1.9652" and 3.3891 when the field view are (0°, 0°),(0°, 2°) and (0°, 4°) correspondingly, which are about 54%65%and 70%of the original errors. And the spot intensities are about 58%, 62%, 63% and 51% of the original when color temperatures of star are 9600 K, 7600 K, 5600 K and 3600 K correspondingly

例如，当响应波长从300~1100nm减小为400~800nm时，星敏感器视场(0°，0°)、(0°，2°)和(0°，4°)处的单颗恒星定位误差分别减小为0.0422&、1.9652&和3.3891，约为原来的54%、65%和70%；色温为9600K、7600K、5600K和3600K的恒星像斑能量分别约为原来的58%、62%、63%和51%。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
