solar-type star

Excepting the plants in the solar system, each star in the sky almost is a galaxy.

天上的星星，除了太阳系的几个行星外，每一颗几乎都代表着一个银河系。

Since a 7-solar-mass is too large to be a white dwarf or neutron star, it must be a black hole.

因为有着7个太阳质量的星体不可能是白矮星或中于星，所以它一定是黑洞。

Multiple exoplanets--planets orbiting stars outside our solar system--were discovered orbiting an M-dwarf star, called GJ 357 in the Hydra constellation.

科学家发现了数颗围绕着长蛇座M矮星GJ357运行的系外行星，系外行星指的是围绕太阳系外恒星运行的行星。

The document issued by the notary public declares Duran to be the "owner of the Sun, a star of spectral typeG2, located in the centre of the solar system, located at an average distance from Earth of about 149600000 kilometres."

公证员发布的文件宣称，杜兰是“太阳的主人。该恒星的光谱类型为G2，位于太阳系中心，与地球的平均距离为1.496亿公里。”

Based on the results of the contrast of star to sky background in daytime, the detectable stellar magnitude limits are computed and analyzed as functions of observing heights, solar zeniths angle, wavebands and stellar spectral types for 3 °× 3 ° field of view.

根据恒星和白天大气背景辐射的对比度，计算和分析了3°×3°视场下，可探测星等极限值随观测高度、太阳天顶角、波段和恒星光谱类型的变化情况。
