We present a comprehensive analysis of a broadband spectral line survey of the Orion Kleinmann-Low nebula (Orion KL), one of the most chemically rich regions in the Galaxy, using the HIFI instrument on board the Herschel Space Observatory. This survey spans a frequency range from 480 to 1907 GHz at a resolution of 1.1 MHz. These observations thus encompass the largest spectral coverage ever obtained toward this high-mass star-forming region in the submillimeter with high spectral resolution and… Expand

A spectroscopic survey of Orion KL between 41.5 and 50 GHz.
TLDR
A sensitive spectral survey of Orion KL, made with one of the 34 m antennas of the Madrid Deep Space Communications Complex in Robledo de Chavela, Spain, is presented, finding most of the detected molecules originate from the low temperature components in Orion KL. Expand
Analysis of the Herschel/HEXOS Spectral Survey Towards Orion South: A massive protostellar envelope with strong external irradiation.
TLDR
It is found that the chemical composition of the gas in the cooler, quiescent component of Orion South more closely resembles that of theQuiescent ridge in Orion-KL, suggesting that higher temperatures and shocks also have an influence on the overall chemistry of OrionSouth. Expand
