摘要：
在形成过程中，巨行星被来自背景恒星盘的气体和尘埃盘所环绕。尽管目前探测到的此类系统较少，但未来几十年即将出现的仪器可能会发现更多。精确的光谱建模将使这些观测能够约束这些形成中系统的特性。为此，我们构建了一个半解析模型，用于几何厚度较大的环行星盘及其行星宿主的结构和辐射特征。将这些辐射特征与二维盘模型的合成观测进行拟合，从而量化（在模型假设下）可得出的参数约束。该机制提供了系统参数值和不确定性的估计，某些参数组合的不确定性明显小于其他组合。然后用此模型拟合实际原行星的观测，结果良好。推导得出的参数为这些天体的局部消光、形成历史和初始熵提供了有用的背景信息。
英文摘要：
As they form, giant planets are surrounded by disks of gas and dust sourced from the background circumstellar disk. Although there have been few detections to date, upcoming instruments are likely to discover many more of these systems in the coming decades. Accurate spectral modeling will enable these observations to constrain the properties of these forming systems. Towards this end, we have constructed a semianalytic model for the structure and radiative signatures of geometrically thick circumplanetary disks and their planet hosts. Fitting these radiative signatures to synthetic observations of a two-dimensional disk model then quantifies the parameter constraints that can be derived (subject to model assumptions). This machinery provides estimates of the values and uncertainties in system parameters, and some combinations of parameters have significantly smaller uncertainties than others. This model is then used to fit observations of real protoplanets, with good results. The derived parameters provide useful context about the local extinction, formation history, and initial entropy of these objects.
