论文摘要
测量原星磁盘中气体和灰尘的量是行星形成研究的关键挑战。在这里，我们提供了一组新的尘埃耗竭因子以及一组原星盘样品的最内向区域的气体和灰尘的相对质量表面密度。我们通过将恒星理论与观察到的磁盘宿主和开放群集星中观察到的耐火元素丰度相结合来做到这一点。我们的结果与从空间分辨的磁盘观测值获得的结果无关，并且与互补。
Measuring the amount of gas and dust in protoplanetary disks is a key challenge in planet formation studies. Here we provide a new set of dust depletion factors and relative mass surface densities of gas and dust for the innermost regions of a sample of protoplanetary disks. We do this by combining stellar theory with observed refractory element abundances in both disk hosts and open cluster stars. Our results are independent of, and complementary to, those obtained from spatially resolved disk observations.
