TL;DR: In this article, the authors used a molecular excitation code that includes the effects of collisions with water and electrons, as well as pumping by the Solar infrared photons (for HCN alone), and found a production rate of 2.9 × 10^(26) s^(−1) and for CH_3OH of2.2 × 10−27) s−1.

TL;DR: The Long Baseline Campaign (LBC) was carried out from 2014 September to late November, culminating in end-to-end observations, calibrations, and imaging of selected Science Verification (SV) targets as discussed by the authors.

TL;DR: In this article, the water abundance in embedded Keplerian disks through spatially-resolved observations of H218O lines was determined by analyzing the water column densities of five young stellar objects.

TL;DR: Water In Star-forming regions with Herschel (WISH) as discussed by the authors is a key program on the Herschel Space Observatory designed to probe the physical and chemical structures of young stellar objects using water and related molecules and to follow the water abundance from collapsing clouds to planet-forming disks.
