Astronomers tried to estimate what solar mass could produce the required luminosity to explain liquid water on these planets.
天文学家试图通过估计太阳质量能产生多少必需的光来解释这些行星上的液态水。
These ultra-high resolution photos allowed the scientists to extend the mass-luminosity relation further than ever before.
这些超高分辨率的照片使得科学家们将质光关系的测量扩展到以前从未涉及到的范围。
If luminosity were a true indicator of mass, most of the mass would be concentrated toward the center.
如果亮度标志着质量，那么大部分质量就应该集中在星系的中心。
In this situation astronomers tacitly assume that stars of the same luminosity and color all have the same mass.
在目前的状况下，天文学家心照不宣地默认，光度和颜色都相同的恒星具有相同的质量。
We discussed the relations between the cross-sections in tree level (and one-loop corrected cross sections) and center-mass energy in the luminosity measuring ranges of GLC.
我们还讨论了在GLC的亮度监测范围内树图及一圈修正后的总截面随质心能量的变化关系。
Due to their high luminosity and high mass-loss rates, massive stars are playing an important role in the studies of modern astrophysics, such as the formation and the evolution of galaxies.
由于高光度和高质量损失率等特性，大质量恒星在星系形成和演化等现代天体物理学的研究中扮演着重要的角色。
