Funny, that's not what the graph is showing, by my interpretation. To me or looks like the innermost stars are the oldest. Then the mid stars are the youngest, then outermost are older again but not the oldest.
I don't think that line necessarily refers to anything going on in the core, but rather "of stars on the outside, the furthest ones are the oldest".
I'm not sure I follow you here, but just to be sure, I'm talking about this image here:
Was that also what you were looking at?
Yeah. And the oldest stars overall are indeed in the galactic centre.
But the specific bit you quoted I read as "of the old stars on the outside, the outermost are the oldest".
Ah okay, I get you. Reading it back again it does indeed seem to be that this is what they mean.
Thanks. ๐
