您要查找的是不是:
- clissical Cepheid 经典造父变星
- Cepheid variable stars are stars whose brightness changes at regular periods. 造父变星是一种光线按规律周期发生变化的恒星。
- Such stars periodically wax and wane in brightness: the longer a Cepheid’s period the bigger and brighter it is. 这类星的亮度有周期性盈亏:周期越长,该造父变星体积就越大,亮度也越高。
- The most impossible energy hit method is launches a bunch of energetic particle to the cepheid variable, like neutrion. 最有可能的能量撞击方法就是向造父变星发射一束高能粒子,如“微中子”。
- Thus, the information may back and forth transmits in Milky Way's network perhaps between these cepheid variables. 这样,信息就可以在银河系的网络之中或是在这些造父变星之间来回传输。
- Zhao Miao Wang city for the week of closure Cepheid, theshi yi afterzhao jian son, named Zhao City. 赵城为周缪王封造父之地,后为赵简子食邑,故名赵城。
- His first great discovery was made when he recognized a Cepheid variable star.It was in the outer area of the great nebula called Andromeda. 他识别出造父变星,做出了第一个重大发现,在仙女座星云的外围区域。
- Forced kindness to introduce that this idea's wonderful place lay in us already to grasp about cepheid variable one century brightness change data. 勒恩德介绍说,“这种想法的美妙之处在于我们已经掌握了关于造父变星一个世纪的亮度变化数据。
- They discovered almost 800 Cepheid variable stars,a special class of pulsating star used for accurate distance measurement. 他们发现了差不多800个造父变星,一种用于准确测量距离的特殊变星。
- This property can be used to reveal the distance to a Cepheid’s parent galaxy, because the star’s period reveals its intrinsic brightness. 这一特性可以用来测算出一造父变星与其源星系之间的距离,因为变星的周期能显示出其内在亮度。
- This makes space telescope invaluable for identifying a rare class of pulsating stars, called Cepheid Variable stars embedded within M100';s spiral arms. 这对于从M100的旋臂中分辨出暗藏的造父变星有着莫大价值。
- Toward this goal, this image was taken by the Hubble Space Telescope in order to help identify key stellar distance markers know as Cepheid variable stars. 为了达到这么目标,这张由哈勃太空望远镜拍摄的影像就是为了帮助确定关键的恒星距离也就是被称为造父变星。
- Edwin Hubble was able to use individual Cepheid variable stars to show that M31 was not nearby swirling gas but rather an entire galaxy like our Milky Way Galaxy. 埃德文.;哈勃利用造父变星来说明M31不是一个临近的旋涡云气,而是与我们银河系一样也是一个完整星系。
- The researchers explained that through a beam energy hit cepheid variable, might cause its essence to elevate temperature and to inflate, thus caused it to have the vibration. 研究人员解释说,通过一束能量撞击造父变星,可以引起其内核升温并膨胀,从而导致其发生震动。
- The times of 6 maxima of the ultrashort-period cepheid variable EH Librae were measured in May to June, 1980, and in January, 1981, with a three channel photoncounting high-speed photoelectric photometer. 我们于1980年5月18、19日及6月15日和1981年1月15日四夜,用高速光电光度计观测了天秤座EHLib,获得6个光度极大时刻。
- Wendy Freedman of the Carnegie Observatories in Pasadena, California, and her colleagues used the Space Telescope to examine the spiral galaxy M100, in which they discovered Cepheid variables. 加州帕萨迪那卡内基天文台的温迪 ( 弗里德曼和她的同事们使用空间望远镜来观察螺旋状星系M100,并在其中发现了造父变星。
- The SHOES team used Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) and the Advanced Camera for Surveys (ACS) to observe 240 Cepheid variable stars across seven galaxies. SHOES团队使用哈勃望远镜的近红外相机和多目标光谱仪(NICMOS)、高级巡天相机(ACS)观测了综括7个星系的240颗造父变星。
