我们提出了一个开放的访问网格3930外部蒸发原行星盘的计算。这涵盖了一系列的盘大小（1- 400 AU），盘质量，紫外线场强（10-10 $^4$ G $_0$）和恒星质量（0.05- 1.9 M $_\odot$）。网格是公开可供下载的，并提供了一种廉价的手段，包括外部光蒸发光盘进化计算。它也可以使用在线工具进行查询，以快速估计瞬时质量损失率（例如，方便评估实际观察到的系统）。“FRIED”网格本身表明，对于围绕恒星$\leq0.3$ M $_\odot$的圆盘，外部光蒸发在小半径（$<50$ AU）下到至少弱至10 G $_0$的紫外线场都是有效的。在尺度的另一端，在$10^4$ G $_0$环境中，即使恒星质量至少高达1.9 M $_\odot$，光蒸发在低至1 AU时也是有效的。我们还说明了在该制度CO生存的光蒸发外流显着的质量损失率，标志着一个系统的一个很好的候选人检测外部光蒸发在弱中间紫外线环境中，通过子开普勒旋转。最后，我们根据Guilloteau等人（2011）的星盘参数对金牛座的星盘进行了说明性的质量损失率估计，发现大约一半的星盘预计会有显著的质量损失，并将CO保留在光蒸发流出物中。
英文摘要：
We present an open access grid of 3930 calculations of externally evaporating protoplanetary discs. This spans a range of disc sizes (1-400AU), disc masses, UV field strengths (10-10$^4$G$_0$) and stellar masses (0.05-1.9M$_\odot$). The grid is publicly available for download, and offers a means of cheaply including external photoevaporation in disc evolutionary calculations. It can also be queried using an online tool for quick estimates of instantaneous mass loss rates (e.g for convenient evaluation of real observed systems). The `FRIED' grid itself illustrates that for discs around stars $\leq0.3$M$_\odot$ external photoevaporation is effective down to small radii ($<50$AU) down to UV fields at least as weak as 10G$_0$. At the other end of the scale, in a $10^4$G$_0$ environment photoevaporation is effective down to 1AU even for stellar masses at least as high as 1.9M$_\odot$. We also illustrate in which regimes CO survives in the photoevaporative outflow for significant mass loss rates; marking a system a good candidate to detect external photoevaporation in weak-intermediate UV environments through sub-Keplerian rotation. Finally we make illustrative mass loss rate estimates for discs in Taurus based on the Guilloteau et al. (2011) star-disc parameters, finding that around half are expected to have both significant mass loss and retain CO in the photoevaporative outflow.
