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…
New constraints on the delivery of cometary water and nitrogen to Earth from the 15N/14N isotopic ratio
D. Hutsemekers, J. Manfroid, E. Jehin +1
New independent constraints on the amount of water delivered to Earth by comets are derived using the 15N/14N isotopic ratio, measured to be roughly twice as high in cometary CN an…
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…
