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.

TL;DR: In this paper, the first protostars gain sufficient mass to ionize the accretion flow, their H II regions are initially gravitationally trapped, but soon begin to rapidly fluctuate between trapped and extended states, in agreement with observations.

TL;DR: In this article, a model of massive star formation by continuing accretion predicts a new class of gravitationally trapped, long-lived, hypercompact H II regions, where the momentum of the accretion flow is sufficient to push the dust grains through a narrow zone of high dust opacity at the ionization boundary and into the H II region where the dust is sublimated.

TL;DR: The first detection of water vapor at high spectral resolution toward a dense cloud on the verge of star formation, the pre-stellar core L1544, was reported in this article.

TL;DR: In this article, the authors investigated the effect that the formation of a massive star has on its own accretion flow and proposed a simple model that includes angular momentum, that of gas flow on ballistic trajectories around a star, and that of a three-stage evolutionary sequence.
