Below the frame center and just to the right of Alnitak lies the Horsehead Nebula, a dark indentation of dense dust that has perhaps the most recognized nebular shapes on the sky. 画面中央偏下,也就是位在参宿一右方的马头星云,由致密的黑暗尘埃组成,应当是天空中最被认可的形状。
The remnant nebular gas pervades the interplanetary space. 星云的残余气体充斥星际空间。
Observation of variables in Ophiuchus Scorpius region& new rapid variables and nebular variables 蛇夫-天蝎暗云区的变星观测&新快变星及星云变星
Accretion Disk and Angular Momentum Loss During Formation of a Star in the Nebular Disk 吸积盘与恒星在星云盘中形成时的角动量损失
Spectrophotometry of n her 1963 in its nebular stage 武仙座1963年新星星云阶段的分光光度
The magnitude of the turbulence then follows directly from the observed line with if the nebular gas temperature is known. 如果已知星云气体的温度,则湍流的大小可直接从观测的谱线宽度得出。
( astronomy) the nebular hypothesis of the origin of the solar system. (天文学)关于太阳系起源的星云假说。
Winds and intense radiation from hot, young, luminous stars in N44 excite and sculpt filaments and streamers of the glowing nebular gas. N44内部炽热年轻亮星的恒星风和强烈辐射,激发四周的云气发出辉光,也雕塑出这些奇形怪状的云气丝。
Ultraviolet radiation from the hot star powers the nebular glow. 热恒星的紫外辐射使星云发光。
Radio astronomers are now able to synthesize the response of a partially filled aperture of large diameter and thus to map variations in nebular brightness. 射电天文学家现在已经能够把部分充满的大直径孔径进行综合,从而描绘出星云亮度变化图。
A discussion on some Antarctic quasi C1 chondrites origin and range of nebular hydrous effect 对南极类C1陨石成因和星云水化作用范围的几点看法
If the chaotic behavior of particles in the proto planetary nebula can be described in terms of the mathematics method in quantum mechanics, the good correspondences between the planetary distances and the radial probability density peaks of the most abundant nebular particles can be found. 如果用量子力学的数学方法来描述原行星星云中的微观粒子的混沌行为,则星云中最丰富的粒子的径向分布几率密度峰与行星的位置很好地对应。
This paper analyses the structure of the outer edge region of the solar nebular disk, and shows that no formation zone of comets can exist there. 本文分析了星云盘外缘区的结构,论证了那里不可能存在彗星形成带。
We propose a model for the formation of a star in a nebular disk on the basis of the accretion disk theory and the phenomena observed in recent years. 本文根据吸秘盘理论与天文观测结果,给出一个恒星在星云盘中形成的模型。
Through the comparative studies on Q-C1 meteorite, C1 meteorite, and other carbonaceous chondrite, the Q-C1 meteorite's origin is inferred that they were results if gas-liquid-solid condensation, gas-solid condensation and hydrous effect in border sheet of nebular disk. 通过类C1陨石与其它球粒陨石及C1陨石成分结构特征的对比,推断它们是星云盘边缘层星云发生气-液-固和气-固联合凝聚作用,同时发生水化作用的产物。
