Molecular composition of comet 46P/Wirtanen from millimetre-wave spectroscopy
N. Biver, D. Bockelée-Morvan, J. Boissier +11
We present the results of a molecular survey of comet 46P/Wirtanen undertaken with the IRAM 30-m and NOEMA radio telescopes in December 2018. Observations at IRAM 30-m during the 1…
Comets at radio wavelengths
Jacques Crovisier, Dominique Bockelée-Morvan, Pierre Colom +1
Comets are considered as the most primitive objects in the Solar System. Their composition provides information on the composition of the primitive solar nebula, 4.6 Gyr ago. The r…
Isotopic ratios of H, C, N, O, and S in comets C/2012 F6 (Lemmon) and C/2014 Q2 (Lovejoy)
N. Biver, R. Moreno, D. Bockelée-Morvan +15
The apparition of bright comets C/2012 F6 (Lemmon) and C/2014 Q2 (Lovejoy) in March-April 2013 and January 2015, combined with the improved observational capabilities of submillime…
Ethyl alcohol and sugar in comet C/2014Q2 (Lovejoy)
Nicolas Biver, Dominique Bockelée-Morvan, Raphaël Moreno +7
The presence of numerous complex organic molecules (COMs; defined as those containing six or more atoms) around protostars shows that star formation is accompanied by an increase o…
Complex organic molecules in comets C/2012 F6 (Lemmon) and C/2013 R1 (Lovejoy): detection of ethylene glycol and formamide
N. Biver, D. Bockelée-Morvan, V. Debout +9
A spectral survey in the 1 mm wavelength range was undertaken in the long-period comets C/2012 F6 (Lemmon) and C/2013 R1 (Lovejoy) using the 30 m telescope of the Institut de radio…
Gas and dust productions of comet 103P/Hartley 2 from millimetre observations: interpreting rotation-induced time variations
J. Boissier, D. Bockelée-Morvan, N. Biver +7
Comet 103P/Hartley 2 made a close approach to the Earth in October 2010. It was the target of an extensive observing campaign and was visited by the Deep Impact spacecraft (mission…
Millimetre continuum observations of comet C/2009 P1 (Garradd)
J. Boissier, D. Bockelée-Morvan, O. Groussin +7
Little is known about the physical properties of the nuclei of Oort cloud comets. Measuring the thermal emission of a nucleus is one of the few means for deriving its size and cons…
Observations of the 18-cm OH lines of comet 103P/Hartley 2 at Nançay in support to the EPOXI and Herschel missions
Jacques Crovisier, Pierre Colom, Nicolas Biver +2
The 18-cm radio lines of the OH radical were observed in comet 103P/Hartley 2 with the Nançay radio telescope in support to its flyby by the EPOXI mission and to observations with…
Molecular investigations of comets C/2002 X5 (Kudo-Fujikawa), C/2002 V1 (NEAT), and C/2006 P1 (McNaught) at small heliocentric distances
N. Biver, D. Bockelée-Morvan, P. Colom +4
We present unique spectroscopic radio observations of comets C/2002 X5 (Kudo-Fujikawa), C/2002 V1 (NEAT), and C/2006 P1 (McNaught), which came within $r_h ~ 0.2 AU of the Sun in 20…
Earth-based detection of the millimetric thermal emission of the nucleus of comet 8P/Tuttle
J. Boissier, O. Groussin, L. Jorda +7
Little is known about the physical properties of cometary nuclei. Apart from space mission targets, measuring the thermal emission of a nucleus is one of the few means to derive it…
Interferometric imaging of carbon monoxide in comet C/1995 O1 (Hale-Bopp): evidence for a strong rotating jet
D. Bockelée-Morvan, F. Henry, N. Biver +6
Observations of the CO J(1-0) 115 GHz and J(2-1) 230 GHz lines in comet C/1995 O1 (Hale-Bopp) were performed with the IRAM Plateau de Bure interferometer on 11 March, 1997. The obs…
The chemical diversity of comets
J. Crovisier, N. Biver, D. Bockelée-Morvan +3
A fundamental question in cometary science is whether the different dynamical classes of comets have different chemical compositions, which would reflect different initial conditio…
