恒星学

This paper focuses on the application of hydrodynamics and magnetohydrodynamics to solar oscillations and accretion process and outflow in star formation.

本文着重讨论了流体和磁流体力学在日震学方面和恒星形成中吸积和外流这两方面的应用。

It is likely that the pre-stellar gas has more angular momentum in theprimordial case, and this is borne out by cosmological simulations.

在原初时期，形成恒星的气体很可能具有更多的角动量，这已得到宇宙学的数值模拟的证实。

Basic quantities in stellar photographic photometry (in particular, colour index and "effective wavelength") are formulated according to the assumptions that: 1 stellar radiation may be represented by some black body equivalent and 2 within the limits of a single photometric "receiver", intensity-wavelength relationship of the radiation may be taken as linear.

本文对着当前的发展，综述了照相方法在恒星光度学中的地位。接着用两个简单的假设，即星体幅射的黑体近似和累积亮度范围中的直线近似，把恒星光度学中的基本定义(如有效波长、等光波长和色指数等)和主要问题(如空间红化，亮度效应等)表以公式。

Major advances have been made in the last a few years, including the discovery of fading X-ray, optical and radio afterglows of GRBs, the identification of host galaxies at cosmological distances, and evidence showing that many GRBs are associated with star-forming regions of the host galaxies and possibly a peculiar type of supernova.

过去几年里γ暴的研究取得了重大突破，包括发现了变暗的X射线、光学和射电余辉，探测到位于宇宙学距离的寄主星系，发现γ暴与恒星形成区成协、甚至可能与超新星关联的证据等等。

I know, but scientists at UCLA and TennesseeStateUniversity noticed a strange ring of debris and dust orbiting a star.

：我知道，但是加利福尼亚大学洛杉矶分校及田那西大学的科学家们注意到一个奇怪碎片和尘土组成的环围绕着一颗恒星运转。

Nuclear Physics 1930, the Star of energy will be satisfied with the solution to the rapid development of the internal structure of stars; Hours map and based on the experimental results, the establishment of a stellar evolution of scientific theory. Einstein's general theory of relativity, in 1917 by the structure of the universe, the establishment of a relativistic cosmology. In 1929 the Hubble Space Telescope found redshifts and distances of the future, relations between the people of the gravitational theory of general relativity River from the data objects, size and structure of the material movement and the formation of modern cosmology.

三十年代原子核物理学的发展﹐使恒星能源的疑问获得满意的解决﹐从而使恒星内部结构理论迅速发展﹔并且依据赫罗图的实测结果﹐确立了恒星演化的科学理论。1917年爱因斯坦用广义相对论分析宇宙的结构﹐创立了相对论宇宙学。1929年哈勃发现了河外星系的谱线红移与距离间的关系﹐以后人们利用广义相对论的引力理论来分析有关河外天体的观测资料﹐探索大尺度上的物质结构和运动﹐这就形成了现代宇宙学。

You'll learn your primary fixed star plus those that influence your astrological chart.

你学你那些影响力小恒星加你召开航天表。

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。
