We have derived a value of 15 N/14 N=× 10-3 in the Jovian atmosphere using data from the
Galileo Probe Mass Spectrometer. Adopting this as the average value for nitrogen in the …

Measurements of the isotopic composition of nitrogen in the solar system are summarized.
We show that the 30% change, during the last 3 to 4 billion years, of 15 N 14 N in solar-wind …

We have used the spectra obtained by the Composite Infrared Spectrometer (CIRS) onboard
the Cassini spacecraft to search for latitudinal variation in the 15N/14N ratio on Jupiter. We …

Determination of the nitrogen isotopic ratios in different bodies of the solar system provides
important information regarding the solar system's origin. We unambiguously identified …

We have analyzed nitrogen, neon and argon abundances and isotopic ratios in target
material exposed in space for 27months to solar wind (SW) irradiation during the Genesis …

We report high-precision measurements of nitrogen and carbon isotopic compositions of a
carbon-bearing titanium-nitride (osbornite) in a calcium-aluminum-rich inclusion (CAI) from …

Using the high-resolution Mass Time-of-Flight (MTOF) spectrometer of the Charge, Element,
and Isotope Analysis System (CELIAS) experiment on board the Solar and Heliospheric …

ABSTRACT Using the Green Bank Telescope, we have obtained accurate measurements of
the 14 N/15 N isotopic ratio in ammonia in two nearby cold, dense molecular clouds …

The relative proportion of the two isotopes of nitrogen, 14N and 15N, varies dramatically
across the Solar System, despite little variation on Earth. NASA's Genesis mission directly …

Isotopic ratios are keys to understanding the origin and early evolution of the solar system in
the context of Galactic nucleosynthesis. The large range of measured 14 N/15 N isotopic …
