The 16OH/18OH and OD/OH isotope ratios in comet C/2002 T7 (LINEAR)
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 A Σ − X Πi ultraviolet bands at 3063 Å (0, 0) and 3121 Å (1, 1) obtained with the Very Large Telescope (VLT) feeding the Ultraviolet-Visual Echelle Spectrograph (UVES). From the OH/OH ratio, we find O/O = 425 ± 55, equal within the uncertainties to the terre...

15 صفحه اولMeasuring Isotope Ratios across the Solar System
Introduction: Stable isotope ratios in C, H, N, O and S are powerful indicators of a wide variety of planetary geophysical processes that can identify origin, transport, temperature history, radiation exposure, atmospheric escape, environmental habitability and biology [1]. For the Allan Hills 84001 meteorite, for example, the C/C ratio identifies it as a Mars (SNC) meteorite; the K/Ar ratio te...
متن کاملMagnesium isotope ratios in Hyades stars
Using classical model atmospheres and an LTE analysis, Mg isotope ratios Mg:Mg:Mg are measured in 32 Hyades dwarfs covering 4000K ≤ Teff ≤ 5000K. We find no significant trend in any isotope ratio versus Teff and the mean isotope ratio is in excellent agreement with the solar value. We determine stellar parameters and Fe abundances for 56 Hyades dwarfs covering 4000K ≤ Teff ≤ 6200K. For stars wa...
متن کاملSilicon Isotope Ratios in Cais: In-situ Laser-ablation Mc-icpms Measurements and Comparisons with Magnesium Isotope Ratios
Introduction: High-precision measurements of Mg/Mg by multiple-collector inductively coupled plasma-source mass spectrometry (MC-ICPMS) have been used recently in our laboratory to constrain the thermal history of calcium aluminum-rich inclusions (CAIs) [1]. Presence of primary zoning profiles in at least some CAIs points to supersolidus and subsolidus diffusion as important factors in controll...
