But I'll take it...also...28.5% argon....

Hm, depends on what you mean to ask. Neither nitrogen nor argon are poisonous per se (unlike oxygen), but both do act as a narcotic at high enough pressures. Even down here on Earth, that is a common problem for deep divers. So poisonous, no; potentially harmful, yes. However, looking at this specific ELW, the partial pressures of both argon and nitrogen are well within safe limits, so breathing the air should be fine.Argon is a noble gas, so not poisonous, right?
Yeah, I've always been a bit fascinated with argon in the ELW atmospheres. I first discovered that it's possible back in 2015. Sept. - as far as I know, nobody posted about that before - and as more "argonic" ELWs were found, it didn't take long to notice that at high enough argon levels, ice starts to appear in surface compositions. If there's ice in an ELW's composition, there's always argon in its atmosphere. However, this isn't true the other way around.
Yeah, but the Forge-generated argon is highly likely to come from elsewhere, due to them being present in likely much larger quantities than in Earth's atmosphere. I say "likely" because we don't actually have all the relevant data on planetary atmospheres (yet?), such as their mass. However, if(!) such quantities of argon generated on ELWs is not a bug (which it could very well be), then it might not come from kalium-40 beta decay, but likely from the parent star itself. I'd find it much more likely that the Forge would model the latter, but not the former.It's weird that argon seems to be tied to ice worlds. While argon is itself technically an "ice" (which is defined astronomically as "anything that's not solid at standard Earth temperature and pressure"), here on Earth, all our argon has apparently been derived from the radioactive decay of potassium-40 in the Earth's rock. So, logically, to get a high argon atmosphere, you should need to have lots of rock, and lots of time for all the K-40 in the rock to decay. The stellar forge apparently does not know this.
Oh, and I learned today that kalium is for some reason called potassium in English. That's pretty weird - but hey, live and learn.
I meant that it's weird that English uses different names for natrium and kalium - namely, sodium and potassium. Yet the symbol is the same, as you don't write Pot-40 (since P and Po are already taken), but K-40. Must be a bit inconvenient when studying chemistry or physics.Potassium was first isolated from potash, hence potassium.
