TL;DR: In this paper, high-resolution (15-24 au) observations of CO isotopologue lines from the Molecules with ALMA on Planet-forming Scales (MAPS) ALMA Large Program were used to retrieve CO gas density distributions, using three independent methods: (1) a thermo-chemical modeling framework based on the CO data, the broadband spectral energy distribution, and the mm-continuum emission; (2) an empirical temperature distribution based on optically thick CO lines; and (3) a direct fit to the C$^{17}$O

HD far infrared emission as a measure of protoplanetary disk mass
TL;DR: In this article, the authors examined the robustness of HD as tracer of the disk gas mass, specifically the effect of gas mass on the HD FIR emission and its sensitivity to the vertical structure.

TL;DR: In this article, the gas outer radius measured from the extent of the CO emission changes with time in a viscously expanding disk, which is a suitable tracer of viscous spreading and whether current observations are consistent with viscous evolution.
