Because xenon is a tracer for two parent isotopes, Xe isotope ratios in meteorites are a powerful tool for studying the formation of the Solar System. The I-Xe method of dating gives the time elapsed between nucleosynthesis and the condensation of a solid object from the solar nebula (xenon being a gas, only that part of it that formed after ...
Xenon isotope geochemistry uses the abundance of xenon ... The meteorite Bjurböle is 4.56 billion years old [13] with an initial 129 I/ 127 I ratio of 1.1×10 −4, ...
Carbonaceous chondrite fission xenon (CCF Xe), are a collection of different isotopes of xenon that were thought to have arisen from the decay of a superheavy element within the island of stability. Early studies proposed that the half life of the theoretical progenitor of CCF Xe to be on the order of 10 8 years. [2]
Because xenon is a tracer for two parent isotopes, xenon isotope ratios in meteorites are a powerful tool for studying the formation of the Solar System. The iodine–xenon method of dating gives the time elapsed between nucleosynthesis and the condensation of a solid object from the solar nebula.
An example of an extinct radionuclide is iodine-129; it decays to xenon-129, a stable isotope of xenon which appears in excess relative to other xenon isotopes. It is found in meteorites that condensed from the primordial Solar System dust cloud and trapped primordial iodine-129 (half life 15.7 million years) sometime in a relative short period ...
It identified two processes, known as space weathering, at work - the meteorite impacts and a phenomenon called solar wind sputtering. "Solar winds carry high-energy charged particles, primarily ...
In this dramatic illustration, a meteor falls toward Earth from space. A pair of asteroids that rammed into Earth more than 35 million years ago seemingly had no climate impacts, scientists said ...
First experimental detection of s-process xenon isotopes was made in 1978, [19] confirming earlier predictions that s-process isotopes would be enriched, nearly pure, in stardust from red giant stars. [20] These discoveries launched new insight into astrophysics and into the origin of meteorites in the Solar System. [21]
