摘要
通过IRAS和H_α资料的比较,我们发现麦哲伦云中有着核一晕结构的HII区往往比弥漫低密度HII区具有更高的F(60tμm)/F(H_α)比值,也可能贡献出更多的远红外辐射.这可以用远红外辐射主要来源于混杂在核内电离气体中的尘埃来解释.
From a comparison of the IRAS and smoothed Hα maps of the Manellanic Clouds, it was found that HII regions with core-halo structures usually have higher F(60(μm)/F(Hα) ratio and possibly emit more FIR than the extended low-density (ELD) HII regions. This is consistent with the model that FIR emission is mainly produced by dust within HII regions.
