Juice-SWI during the Lunar-Earth-Gravity-Assist (LEGA) - Part 2: Instrument operations
T. Cavalié, R. Moreno, L. Rezac +17
The Jupiter Icy Moons Explorer (Juice) embarked in 2023 on a 8-year interplanetary journey to Jupiter and its icy moons. The Submillimetre Wave Instrument (SWI) is one of the ten s…
Combined model for , , and spin-state chemistry in molecular clouds
O. Sipilä, L. Colzi, E. Roueff +3
We present a new gas-grain chemical model for the combined isotopic fractionation of carbon and nitrogen in molecular clouds, in which the isotope chemistry of carbon and nitrogen…
Similar levels of deuteration in the pre-stellar core L1544 and the protostellar core HH211
K. Giers, S. Spezzano, P. Caselli +6
In the centre of pre-stellar cores, deuterium fractionation is enhanced due to the low temperatures and high densities. Therefore, the chemistry of deuterated molecules can be used…
Molecular Outgassing in Centaur 29P/Schwassmann-Wachmann 1 During Its Exceptional 2021 Outburst: Coordinated Multi-Wavelength Observations Using nFLASH at APEX and iSHELL at the NASA-IRTF
Nathan X. Roth, Stefanie N. Milam, Michael A. DiSanti +13
The extraordinary 2021 September-October outburst of Centaur 29P/Schwassmann-Wachmann 1 afforded an opportunity to test the composition of primitive Kuiper disk material at high se…
High resolution study of outflows and chemical environment of First Hydrostatic Core candidate Chamaeleon-MMS1
Veronica Allen, Martin A. Cordiner, Gilles Adande +3
The earliest stages of low-mass star-formation are unclear, but it has been proposed that Chamaeleon-MMS1 is a candidate First Hydrostatic Core (FHSC), the transition stage between…
A Search for O_2 in CO-depleted Molecular Cloud Cores with Herschel
Eva S. Wirström, Steven B. Charnley, Martin A. Cordiner +1
The general lack of molecular oxygen in molecular clouds is an outstanding problem in astrochemistry. Extensive searches with SWAS, Odin and Herschel have only produced two detecti…
On the nature of the enigmatic object IRAS 19312+1950: A rare phase of massive star formation?
M. A. Cordiner, A. C. A. Boogert, S. B. Charnley +7
IRAS 19312+1950 is a peculiar object that has eluded firm characterization since its discovery, with combined maser properties similar to an evolved star and a young stellar object…
Ortho-to-para ratio of NH2. Herschel-HIFI observations of ortho- and para-NH2 rotational transitions towards W31C, W49N, W51 and G34.3+0.1
C. M. Persson, A. O. H. Olofsson, R. Le Gal +10
We have used the Herschel-HIFI instrument to observe both nuclear spin symmetries of amidogen (NH2) towards the high-mass star-forming regions W31C (G10.6-0.4), W49N (G43.2-0.1), W…
On the accretion process in a high-mass star forming region - A multitransitional THz Herschel-HIFI study of ammonia toward G34.26+0.15
M. Hajigholi, C. M. Persson, E. S. Wirström +8
[Abridged] Our aim is to explore the gas dynamics and the accretion process in the early phase of high-mass star formation. The inward motion of molecular gas in the massive star f…
Upper limits to interstellar NH+ and para-NH2- abundances. Herschel-HIFI observations towards Sgr B2 (M) and G10.6-0.4 (W31C)
C. M. Persson, M. Hajigholi, G. E. Hassel +12
The understanding of interstellar nitrogen chemistry has improved significantly with recent results from the Herschel Space Observatory. To set even better constraints, we report h…
Cold Water Vapor in the Barnard 5 Molecular Cloud
E. S. Wirström, S. B. Charnley, C. M. Persson +3
After more than 30 years of investigations, the nature of gas-grain interactions at low temperatures remains an unresolved issue in astrochemistry. Water ice is the dominant ice fo…
On the ubiquity of molecular anions in the dense interstellar medium
M. A. Cordiner, J. V. Buckle, E. S. Wirström +2
Results are presented from a survey for molecular anions in seven nearby Galactic star-forming cores and molecular clouds. The hydrocarbon anion C6H- is detected in all seven targe…
Isotopic Anomalies in Primitive Solar System Matter: Spin-state Dependent Fractionation of Nitrogen and Deuterium in Interstellar Clouds
E. S. Wirström, S. B. Charnley, M. A. Cordiner +1
Organic material found in meteorites and interplanetary dust particles is enriched in D and 15N. This is consistent with the idea that the functional groups carrying these isotopic…
Organic chemistry of low-mass star-forming cores I: 7 mm spectroscopy of Chamaeleon MMS1
Martin A. Cordiner, Steven B. Charnley, Eva S. Wirström +1
Observations are presented of emission lines from organic molecules at frequencies 32 - 50 GHz in the vicinity of Chamaeleon MMS1. This chemically-rich dense cloud core habours an…
