Local Group中有灰尘

Dust in the Local Group

Aigen Li, Shu Wang, Jian Gao, B. W. Jiang

摘要:

尘埃如何吸收和散射星光作为波长的函数(称为星际消光曲线)对于校正尘埃消光的影响至关重要,从而推断出红色天体的真实亮度和颜色。与消光光谱特征一起,消光曲线包含了关于尘埃粒度分布和成分的重要信息。这篇综述总结了我们目前对银河系尘埃消光的认识,三个本星系群星系(即,小麦哲伦云和大麦云,以及M31),以及本星系群之外的星系。

英文摘要:

How dust absorbs and scatters starlight as a function of wavelength (known as the interstellar extinction curve) is crucial for correcting for the effects of dust extinction in inferring the true luminosity and colors of reddened astrophysical objects. Together with the extinction spectral features, the extinction curve contains important information about the dust size distribution and composition. This review summarizes our current knowledge of the dust extinction of the Milky Way, three Local Group galaxies (i.e., the Small and Large Magellanic Clouds, and M31), and galaxies beyond the Local Group.
