给出了恒星形成区L1641S的H波段的偏振成像和Ks波段的近红外成像的结果.反射星云Re50和Re50N分别坐落在该区域的南北.两个星云的偏振图像均呈现出高偏振度和中心对称的特点,表明星云内的发射主要以尘埃的单次散射为主,且尘埃的尺寸较小.Re50N星云中存在两个红外点源,其中IRS1是两个星云的红外照亮源,也是该区域CO外流的驱动源,而点源IRS2可能提供了星云光学波段发射所需的大量光子.L1641S的外流结构符合表面散射模型,外流的倾角大约为30°.通过偏振弧结构,我们进一步证认了Re50N星云的双极型结构.
The results of H-band polarization imaging and Ks-band NIR imaging of the star formation region L1641S are given.The reflection nebulae Re50 and Re50N are located respectively in the north and south of the region.The polarization images of both nebulae show high polarization and center Symmetric characteristics indicate that the emission in the nebula is dominated by single scattering of dust and the size of the dust is small. There are two infrared point sources in the Re50N nebula, of which IRS1 is the infrared illuminant of two nebulae Region CO outflow, and the point source IRS2 may provide a large number of photons required for the launch of the nebula optical band.The outflow structure of L1641S accords with the surface scattering model, and the outflow angle is about 30 °. We further confirm by the polarized arc structure The bipolar structure of the Re50N nebula.
