第一个流体静力学核心候选者的SED能揭示它们的性质吗？
What can the SEDs of first hydrostatic core candidates reveal about their nature?
摘要：
第一个流体静力学核心（FHSC）是恒星形成模拟中形成的第一个稳定物体。这个阶段还没有被明确观察到，尽管已经报道了几种候选的FHSC。我们已经产生了合成光谱能量分布（SED）的三维流体动力学模拟的前恒星的核心进行引力坍缩的各种初始条件。初始旋转速率、半径和质量的变化导致SED峰值和远红外通量的位置不同。其次，我们试图拟合的SED的五个FHSC候选人从文献和五个新发现的FHSC候选人位于Serpens南分子云模拟SED。最有前途的FHSC候选人是由有限数量的模型SED与一致的属性，这表明SED可以是有用的，用于放置的年龄和旋转速率的源的约束。我们认为最有可能处于FHSC阶段的源是B1-bN，CB 17-MMS，Aqu-MM 1和Serpens South候选K242。我们无法用合理的参数拟合SerpS-MM 22，Per-Bolo 58和Chamaeleon-MMS 1，这表明它们可能更加进化。
英文摘要：
The first hydrostatic core (FHSC) is the first stable object to form in simulations of star formation. This stage has yet to be observed definitively, although several candidate FHSCs have been reported. We have produced synthetic spectral energy distributions (SEDs) from 3D hydrodynamical simulations of pre-stellar cores undergoing gravitational collapse for a variety of initial conditions. Variations in the initial rotation rate, radius and mass lead to differences in the location of the SED peak and far-infrared flux. Secondly, we attempt to fit the SEDs of five FHSC candidates from the literature and five newly identified FHSC candidates located in the Serpens South molecular cloud with simulated SEDs. The most promising FHSC candidates are fitted by a limited number of model SEDs with consistent properties, which suggests the SED can be useful for placing constraints on the age and rotation rate of the source. The sources we consider most likely to be in FHSC phase are B1-bN, CB17-MMS, Aqu-MM1 and Serpens South candidate K242. We were unable to fit SerpS-MM22, Per-Bolo 58 and Chamaeleon-MMS1 with reasonable parameters, which indicates that they are likely to be more evolved.
