The CN isotopic ratios in comets
J. Manfroid, E. Jehin, D. Hutsemékers +6
Our aim is to determine the isotopic ratios {C/C}{} and {N/N}{} in a variety of comets and link these measurements to the formation and evolution of the…
The 16OH/18OH and OD/OH isotope ratios in comet C/2002 T7 (LINEAR)
D. Hutsemekers, J. Manfroid, E. Jehin +2
The 16OH/18OH and OD/OH isotope ratios are measured in the Oort-Cloud comet C/2002 T7 (LINEAR) through ground-based observations of the OH ultraviolet bands at 3063 A (0,0) and 312…
Large excess of heavy nitrogen in both hydrogen cyanide and cyanogen from comet 17P/Holmes
D. Bockelée-Morvan, N. Biver, E. Jehin +15
From millimeter and optical observations of the Jupiter-family comet 17P/Holmes performed soon after its huge outburst of October 24, 2007, we derive 14 N/15N = 139 +/- 26 in HCN,…
The impact and rotational lightcurves of Comet 9P/Tempel 1
Jean Manfroid, Damien Hutsemékers, Emmanuël Jehin +6
UVES and HIRES high-resolution spectra of comet 9P/Tempel 1 are used to investigate the impact and rotational light curves of various species with a view toward building a simple m…
Deep Impact : High Resolution Optical Spectroscopy with the ESO VLT and the Keck 1 telescope
E. Jehin, J. Manfroid, D. Hutsemekers +6
We report on observations of comet 9P/Tempel 1 carried out before, during, and after the NASA DEEP IMPACT event (UT July 4), with the optical spectrometers UVES and HIRES mounted o…
Isotopic abundances of carbon and nitrogen in Jupiter-family and Oort Cloud comets
D. Hutsemekers, J. Manfroid, E. Jehin +5
The 12C14N/12C15N and 12C14N/13C14N isotopic ratios are determined for the first time in a Jupiter-family comet, 88P/1981 Q1 Howell, and in the chemically peculiar Oort Cloud comet…
