AbstractDeuterium fractionations in cometary ices provide important clues to the origin and evolution of comets. Mass spectrometers aboard spaceprobe Giotto revealed the first accurate D/H ratios in the water of Comet 1P/Halley. Ground-based observations of HDO in Comets C/1996 B2 (Hyakutake) and C/1995 O1 (Hale-Bopp), the detection of DCN in Comet Hale-Bopp, and upper limits for several other D-bearing molecules complement our limited sample of D/H measurements. On the basis of this data set…

D/H in the refractory organics of comet 67P/Churyumov-Gerasimenko measured by Rosetta/COSIMA

The D/H ratio is a clue to the origin and evolution of hydrogen-bearing chemical species in Solar system materials. D/H has been observed in the coma of many comets, but most such measurements have

Some Features of Comet Hale–Bopp (According to the Observations of 1995–1998)

Abstract “The Great Comet of 1997” was a significant event in cometary physics. Numerous interesting scientific studies are devoted to this comet. Unfortunately, in the Russian scientific literature,

Isotopic abundances of carbon and nitrogen in jupiter-family and oort cloud comets

The 12 C 14 N/ 12 C 15 N and 12 C 14 N/ 13 C 14 N isotopic ratios are determined for the first time in a Jupiter-family comet, 88P/1981 Ql Howell, and in the chemically peculiar Oort Cloud comet

The abundances of constituents of Titan's atmosphere from the GCMS instrument on the Huygens probe

Direct atmospheric measurements from the Gas Chromatograph Mass Spectrometer (GCMS), including altitude profiles of the constituents, isotopic ratios and trace species (including organic compounds), were reported, confirming the primary constituents were confirmed to be nitrogen and methane.

Martian Volatiles: Isotopic Composition, Origin, and Evolution

Information about the composition of volatiles in the Martian atmosphere and interior derives from Viking spacecraft and ground-based measurements, and especially from measurements of volatiles

A long-tailed , seed-eating bird from the Early Cretaceous of China

show the appropriate hyperbolic relationship (Fig. 2b) predicted by mixing of unmodified terrestrial and meteorite debris. We propose that weathering of meteoritic debris caused preferential

Physics and chemistry of icy particles in the universe : answers from microgravity

During the last century, the presence of icy particles throughout the universe has been con:rmed by numerous ground and space based observations. Ultrathin icy layers are known to cover dust

Experimental and theoretical simulation of sublimating dusty water ice with implications for D/H ratios of water ice on Comets and Mars

Sublimation experiments have been carried out to determine the effect of the mineral dust content of porous ices on the isotopic composition of the sublimate gas over medium (days to weeks)
