I'm no expert on stars, so I have no idea what having extra extra lead or other metals in a star's atmosphere means. I'm just throwing the article out there for the more knowledgeable.

Same for me, i said: "Mhhh, why a topic about music in science and astronomy discussions?" biggrin

I have to wonder if the magenta light in the artist's impression is realistic.
Consider the fact that magenta == white minus green, so the star would have to emit large amounts of blue and red light, without emitting large amounts of green light.
It seems unlikely that a star at 38000 K would emit much of anything besides violet-blue and face-melting amounts of UV, especially considering the peak wavelength should be around 76 nm, not two peaks at 700 and 400.
Maybe if the star has a large outer atmosphere that filters out ~90% of green and 50% of blue light but is transparent to red light, it could be magenta like that, but this seem unlikely.
And by large outer atmosphere, I mean an atmosphere that is large enough to emit primarily red light instead of blue.

Yeah, the artist's rendition is not at all representative of what it would look like to the human eye. Even the caption says the high temperature would make it appear bluish, not magenta. :S

At 38000K it is right up there with the hottest O type stars, where most of the emission is in UV. You wouldn't want to look at it from anywhere remotely close by, even with cool sunglasses like these. cool

I think I once saw a screenshot of a so called "Zirconium Star" in SE (might have been old version) is this possible?




I will be inactive on this forum for the time being. Might come back eventually

There is, but it's catalog.

How can you create such a star? You just put "Zirconium" as the class?
