论文摘要
紫外线(UV)辐射场的分布在分子云的物理环境上提供了关键的约束。在我们的太阳系的1 kpc之内,并培养了不同质量的质体,古尔德带中的巨大分子云提供了解决恒星形成区域中紫外线田间结构的绝佳机会。我们对Herschel Gould Belt调查(HGB)进行了光谱能量分布(SED)拟合。用灰尘代码的尘埃辐射转移分析应用于14个分子络合物中的23个区域,从而导致这些区域的辐射场的空间分布。对于具有恒星形成速率独立测量的15个区域中的10个,它们的恒星形成速率和紫外线辐射强度在很大程度上符合先前研究中发现的线性相关性。
The distribution of ultraviolet (UV) radiation field provides critical constraints on the physical environments of molecular clouds. Within 1 kpc of our solar system and fostering protostars of different masses, the giant molecular clouds in the Gould Belt present an excellent opportunity to resolve the UV field structure in star forming regions. We performed spectral energy distribution (SED) fitting of the archival data from the Herschel Gould Belt Survey (HGBS). Dust radiative transfer analysis with the DUSTY code were applied to 23 regions in 14 molecular complexes of the Gould Belt, resulting in the spatial distribution of radiation field in these regions. For 10 of 15 regions with independent measurements of star formation rate, their star formation rate and UV radiation intensity largely conform to a linear correlation found in previous studies.
