Spatially extended OH+ emission from the Orion Bar and Ridge
Floris van der Tak, Zsofia Nagy, Volker Ossenkopf +5
We report the first detection of a Galactic source of OH+ line emission: the Orion Bar, a bright nearby photon-dominated region. Line emission is detected over ~1' (0.12 pc), traci…
Herschel/HIFI observations of a new interstellar water maser: the 5(32)-4(41) transition at 620.701 GHz
David A. Neufeld, Yuanwei Wu, Alex Kraus +4
Using the Herschel Space Observatory's Heterodyne Instrument for the Far-Infrared (HIFI), we have performed mapping observations of the 620.701 GHz 5(32)-4(41) transition of ortho-…
The chemistry of ions in the Orion Bar I. - CH+, SH+, and CF+: The effect of high electron density and vibrationally excited H2 in a warm PDR surface
Z. Nagy, F. F. S. Van der Tak, V. Ossenkopf +8
The abundances of interstellar CH+ and SH+ are not well understood as their most likely formation channels are highly endothermic. Using data from Herschel, we study the formation…
