Determination of the wavelength dependence of interstellar polarization in the near-infrared

在近红外波段，对不同区域（朝向银河系中心、银河面和恒星形成区域）的天体已经实现了高精度的偏振测量，这反过来又强烈地限制了星际介质中的尘埃成分。此外，在这些观测中，我们对恒星形成区域的磁场有了新的发现，以及对空间分布、x射线发射、变星特性和它们的年龄有了新的发现。

In the near-infrared wavelengths, polarization measurements with high accuracies have been achieved for astronomical objects in a variety of regions(toward the Galactic center, Galactic plane, and star forming regions), which in turn constrains the dust components in the interstellar medium quite strongly. Also, we have made new findings about the magnetic field in the star forming regions, plus new findings about the spatial distributions, x-ray emission, variable star properties and their ages, in these observations.
