The Herschel-Heterodyne Instrument for the Far-Infrared (HIFI) [PDF]
EAS Publications Series, 2008 This paper describes the Heterodyne Instrument for the Far-Infrared (HIFI) to be launched onboard of ESA's Herschel Space Observatory, by 2008. The instrument is designed to be electronically tunable over a wide and continuous frequency range in the Far Infrared, with velocity resolutions better than 0.1 km s-1 and a high sensitivity.de Graauw, Th., Whyborn, N., Caux, E., Phillips, T., Stutzki, J., Tielens, A., Güsten, R., Helmich, F., Luinge, W., MartÃn-Pintado, J., Pearson, J., Planesas, P., Roelfsema, P., Saraceno, P., Schieder, R., Wildeman, K., Wafelbakker, K. +16 moreopenaire +4 more sourcesNeptune’s HCl upper limit from Herschel/HIFI [PDF]
Icarus, 2021 Abstract Here we search for hydrogen chloride (HCl) in Neptune’s stratosphere using observations of the 1876.22 GHz J=3–2 transition from the Heterodyne Instrument for the Far-Infrared (HIFI) on Herschel. Observations comprise a 7.2 hr disc-averaged integration, originally designed to investigate stratospheric methane.N.A. Teanby, B. Gould, P.G.J.

Astronomy & Astrophysics, 2011 Aims. In this paper the calibration and in-orbit performance of the Heterodyne Instrument for the Far-Infrared (HIFI) is described.Methods. The calibration of HIFI is based on a combination of ground and in-flight tests. Dedicated ground tests to determine those instrument parameters that can only be measured accurately using controlled laboratory ...Roelfsema, P. R., Helmich, F.

Astronomy & Astrophysics, 2017 Context.The HIFI instrument on theHerschelSpace Observatory performed over 9100 astronomical observations, almost 900 of which were calibration observations in the course of the nearly four-yearHerschelmission. The data from each observation had to be converted from raw telemetry into calibrated products and were included in theHerschelScience Archive ...Shipman, R. F., Beaulieu, S.

Astronomy and Astrophysics, 2010 Circumstellar envelopes (CSEs) of a variety of evolved stars have been found to contain ammonia (NH3) in amounts that exceed predictions from conventional chemical models by many orders of magnitude. The observations reported here were performed in order to better constrain the NH3 abundance in the CSEs of four, quite diverse, oxygen-rich stars using ...Menten, K.
