标题： Star formation in clusters: a survey of compact mm-wave sources in the Serpens core

摘要： 我们报告了对蛇夫座核心内部5.5'x5.5'区域内的紧凑3 mm连续谱源的毫米波干涉测量调查结果。 我们检测到32个高于4.0 mJy/beam的离散源，其中21个是在毫米波段的新检测结果。 通过将我们的数据与已发表的红外巡天数据进行比较，我们估计有26个源可能是原恒星凝聚体，并假设尘埃颗粒的光学薄热辐射来推导它们的质量。 云团的质量谱dN/dM~M^(-2.1)与恒星初始质量函数一致，支持年轻星团中的恒星质量是由湍流云核的碎片化决定的观点。 显示英文摘要

摘要： We report the results of a millimeter interferometric survey of compact 3 mm continuum sources in the inner 5.5'x5.5' region of the Serpens core. We detect 32 discrete sources above 4.0 mJy/beam, 21 of which are new detections at millimeter wavelengths. By comparing our data with published infrared surveys, we estimate that 26 sources are probably protostellar condensations and derive their mass assuming optically thin thermal emission from dust grains. The mass spectrum of the clumps, dN/dM~M^(-2.1), is consistent with the stellar initial mass function, supporting the idea that the stellar masses in young clusters are determined by the fragmentation of turbulent cloud cores.
