Nice!
A couple last name Brothwell wrote a book on cuisine of the Roman Empire.
Ultimately, yeah.
If Sol is the coalesced remnants of an earlier star, its lifetime would be limited.
It would reach an “antitypical” phase where it would enter death throes “early”.
Similar to certain blue straggler stars with “anomalous ages”.

and something of interest to X-Planets, probably good to just add it to the catalog.

Still not too much to worry about. :’)
*shrug* Any civilization that discovered a way to use Einstein’s spooky action at a distance would drop RF communications in an instant.
Why settle for poky-slow radio for instant communications?
Why use radio where any munchkin with an antenna can intercept your signal?
Why lose signal strength with the inverse square of the distance?
Tomorrow morning, “Why is the sun red and bloated?”
“Because Darksheare and Sunkenciv ticked it off!”

“strange xenon”
Jupiter’s helium-rich atmosphere contains xenon with excess 136Xe and the ratio of r-products more closely resembles “strange” xenon (Xe-X, alias Xe-HL) seen in carbonaceous chondrites than xenon seen in the solar wind (SW-Xe ). The linkage of primordial helium with Xe-X, as seen on a microscopic scale in meteorites, apparently extended across planetary distances in the solar nebula, This is expected if the solar system acquired its present chemical and isotopic diversity directly from debris of the star that produced our elements.
...
What makes xenon the noble gas of choice? Besides the fact that it has more stable isotopes than any other noble gas and lies in the region of the mass spectrum that has the least contamination, it has also provided the most information about the ea rly history of the solar system and the origin of its elements. Xenon isotopes contain decay products of the first two extinct radionuclides3,4 discovered in the solar system in the 1960s. In 1960, xenon provided the first hint that isotopic ratios of primordial elements might vary within the solar system5, and xenon isotopes first carried the message in 1972 that one form of xenon, Xe-X, might have been “... added to our solar system from a nearby supernova, although no evidence for the addition of products from a separate nucleosynthesis event has been found in other elements.” (MANUEL et al.6, p. 100)
...
Soon after confirmation7 of excess 124,126Xe and 134,136Xe in the Allende meteorite from the p- and r-processes of nucleosynthesis8, xenon isotopes in the Murchison meteorite revealed a complementary component9, Xe-S, characterized by excess 128-132Xe from the s-process of nucleosynthesis8. More important for the present study are the finding10 and confirmation11 that primordial He is always closely coupled with isotopically strange Xe-X in meteorites.

Wasting time wondering about things that cannot be changed and do not matter.
Who cares how much iron is in the Universe, and why?
;’)
Thanks BL!
My daughter was just lamenting on her science project due tomorrow on the various stages of the sun. “What does it matter - it’s not like anyone around now is going to SEE any of it!!??”
I didn’t have a good answer, except for the “knowledge for knowledge’s sake”. That, and learning about the sun and it’s energy to debunk the AGW crowd!
Posting in a science topic despite not caring about science is the quintessential waste of time.
There is precedence in the universe for odd things happening to stars.
V838 Monocerotis started out as an under luminous f-type dear not unlike Sol.
It had some outburst, grew rapidly, and briefly was an L-type supergiant.
“Dear”?
*sigh*
“Under luminous f-type dwarf” .
I hate autocorrect.
