Context. The ESA Rosetta spacecraft (S/C) is tracking comet 67P/Churyumov-Gerasimenko in close vicinity. This prolonged encounter enables studying the evolution of the volatile …
The composition of cometary ices provides key information on the chemical and physical properties of the outer solar nebula where comets formed, 4.6 Gy ago. This chapter …

We detected CH4 in eight Oort cloud comets using high-dispersion (λ/Δλ∼ 2× 104) infrared spectra acquired with CSHELL at NASA's IRTF and NIRSPEC at the WM Keck Observatory …
We measured the chemical composition of Comet C/2007 W1 (Boattini) using the long-slit echelle grating spectrograph at Keck-2 (NIRSPEC) on 2008 July 9 and 10. We sampled 11 …
Multiple non-resonance fluorescence lines of water (H2O) were detected in Comet 153/P Ikeya–Zhang (2002 C1) between UT 2002 March 21.9 (Rh= 0.51 AU) and April 13.9 (Rh …
