Article is SUPER short on details. What is “dark matter heating” and is the claim here that these stars are not creating heat and light through fusion?
We don't even know what dark matter even is -- or if it actually exists. We just assume, by fitting data into our existing models, which might well be flawed. It's just all "our best guess" right now, so it's not surprising that the article is vague.
Yeah, clearly. Someone (hopefully smarter than me) came up with a concept, and a few extra details as to what they mean would have been appreciated in the article.
It's somewhat controversial. I think the majority of astrophysicists say dark matter is probably or even likely real. But there are a small and growing number who dispute this and say the standard model needs revision, and we possibly misunderstand or miscalculate gravity models over vast distances. Sabine Hossenfelder on YouTube has some interesting videos about it.
