TL;DR: In this paper, the calibration and in-orbit performance of the Heterodyne Instrument for the Far-Infrared (HIFI) is described based on a combination of ground and in flight tests.

TL;DR: It is reported that the unsaturated hydrocarbon molecule cyclic-C3H2 resides in the infalling rotating envelope, whereas sulphur monoxide is enhanced in the transition zone at the radius of the centrifugal barrier (100 ± 20 au), which is the radius at which the kinetic energy of the inf falling gas is converted to rotational energy.
Journal ArticleDOI
The Origin of Complex Organic Molecules in Prestellar Cores
Charlotte Vastel,Charlotte Vastel,Cecilia Ceccarelli,Cecilia Ceccarelli,Bertrand Lefloch,Bertrand Lefloch,Rafael Bachiller +6 more
TL;DR: In this article, an unbiased spectral survey of the 3 mm band at the IRAM 30 m telescope as part of the Large Program ASAI (LPASAI) was performed to detect complex organic molecules (COMs) in cold prestellar cores.
Journal ArticleDOI
Chemical modeling of L183 (= L134N) : an estimate of the ortho/para H2 ratio
Laurent Pagani,Charlotte Vastel,Edouard Hugo,Viatcheslav Kokoouline,Chris H. Greene,Aurore Bacmann,E. Bayet,Cecilia Ceccarelli,Renshui Peng,S. Schlemmer +9 more
TL;DR: In this paper, the ortho-para H2 ratio of the L183 prestellar core was investigated and the authors derived its profile using the N2D^+/N2H+ ratio.

TL;DR: In this paper, the authors used the Herschel HIFI instrument in dual beam switch mode to observe the ground state rotational transitions of the reactive ions OH +, H 2O + and H 3O + along the line of sight to the submillimeter continuum source G10.4 (W31C).
