Almost pretty much the same thing really.
Consider that our sun contains 99.86% of the mass of our Solar System.
If you dumped that into a Sun-sized metal-poor star, it would probably pass for metal-rich.
- defrost 3y agoGiven our sun is a population I or heavy-element-rich star that'd almost certainly be the case ... the elements that didn't fall into our sun to make it so remained in orbit and are also heavy element rich (obviously relatively more so that the mostly H-He sun). A Sun sized metal poor star wouldn't be surrounded by large amounts of orbiting heavy elements .. that would suggest even larger amounts failed to orbit and fell into that star. ( I'll freely confess to being decades out of date on the conjectured life of stars though, these days I mainly do geophysics related to astrophysics (cancelling out ground effects from SKA type projects) )
- pvg 3y agoOh I just meant that amount of metal for some (entirely made up) stars would already be pretty metal. The sort of astro out of an Asimov joke story. But as the black hole approached, Hieronymus noted there was no gravitational effect. He studied it more closely and announced, with a chuckle, that it was not a black hole after all. “It’s nothing,” he said. “Just an ordinary asteroid someone has painted black.”
