Netizen asked: What is strange xenon? Why is there a difference in the ratio of Xe136/134 on solar wind and Jupiter ? Is this important?
The author answered : "Xenon" has 9 stable isotopes , and there are about 20 isotopes that decay quickly. (Isotopes are atoms with the same number of protons, so the chemical properties are the same, but the number of neutrons in the nucleus is different.) On Earth, the abundance of different isotopes of "xenon" has a specific ratio . For example, the two least common isotopes on Earth are Xe134 (10%) and Xe136 (8%). "Weird xenon" seems to refer to the different isotope ratios found in meteorites, but it's not a commonly used term.
I think you must have read the theory of foreign Dr. Oliver Manuel about "the sun is mainly composed of iron". He used the "xenon" ratio to support his view, claiming that the differences between Jupiter and the solar wind proved that the solar system was formed in a supernova explosion and that the sun was made of iron.
They claim that the strange mixture of xenon isotopes in meteorites could not have formed unless the solar system formed in a supernova explosion. In my opinion, this does not hold true. We know that the gas clouds that make up the solar system contain heavy metals, so there must be remnants of several supernova explosions. A mixture of xenon gas can easily become a tracer of this material without the need for the solar system to have formed in a supernova. In fact, Dr. Manuel's work measuring isotope ratios in meteorites played a very important role in proving that the gas clouds formed in the solar system were enriched by more than one supernova.
The Xe136/134 ratio on Jupiter has been measured to be different from the Xe136/134 ratio in the solar wind. Dr. Manuel theorizes that this proves that the central region of the solar system is made up of the supernova's interior, while the outer regions are made up of the exterior. As far as I know, no other scientist has put such importance into a small detail. Isotope ratios are difficult to measure and even harder to interpret, so I don't want to base my theory on them. In my opinion, the overwhelming evidence supporting the standard scenario of solar system formation far outweighs this. Jupiter and the Sun are both extremely complex celestial bodies, with a very complex mix of atoms. This can easily change the isotope ratio of "xenon". I don't think the difference in ratios really means anything.
It seems to me that the matter that makes up our system probably came from not one, but several supernovae, although I'm assuming you don't believe that our sun was formed from the core of a supernova. I'm weak in physics, so maybe you can help with some nucleoside questions: What process creates the "weird ratio of xenon" that is different from the ratio of "xenon" we see in the solar wind? Are you working on Any hint that there might be other ratios that have not yet been measured?
It is widely accepted that the gas, the product of the formation of the Sun and Solar System must have been abundant in more than one supernova, as I mentioned above some of Dr. Manuel's work on meteorites provides sufficient ratios for this scenario some of the first evidence. We see an enrichment of supernovae in other galaxies and in other regions of our own galaxy - there seems to be a strong connection between supernovae and star formation - perhaps the shock wave from a supernova is necessary to trigger the collapse of (or certainly will help).

I don't think the measured xenon isotope ratios mean anything. The ratios produced during nucleosynthesis are due to fine adjustments and what you do in the beginning. Additionally, these ratios are difficult to measure and may change through mixing processes in the sun. (Heavier isotopes may preferentially fall at the center of the Sun). I believe that using these isotopes as the primary evidence for this extraordinary claim is scientifically untenable.

Supernova is a violent explosion that some stars experience when they are near the end of their evolution. Such explosions are extremely bright, and the bursts of electromagnetic radiation often illuminate the entire galaxy where they are located, and may last for weeks to months before gradually decaying. During this period, the radiation energy released by a supernova can be equivalent to the total radiation energy of the sun in its lifetime.
Xenon isotopes , among which there are 5 stable isotopes and 2 observationally stable isotopes. These 7 isotopes can be found in the natural xenon element. They are the elements with the second most stable elements among all elements. In addition to these stable isotopes, xenon has more than 40 unstable isotopes. The longest-lived one is ^¹²⁴Xe, which undergoes double beta decay and has a half-life of 2.11×10^²¹ years. The relative proportions of xenon isotopes play an important role in studying the early history of the solar system.
