stellar magnitude

A simple double temperature model has been developed to study the effects of stellar spots on the apparent magnitude, colour and the apparent lithium abundance of active stars.

发展了一种简单的双温模型用于研究黑子对活动星的视星等、颜色和视Li丰度的影响。

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。

The results show that the detectable stellar magnitude limits linearly increase with observing height and solar zenith angle.

结果表明：可探测星等极限值随观测高度和太阳天顶角的增加接近线性增加；
