Has someone got a quick explainer for why adding a planet would result in less lithium? Is it just that a super-earth would be big enough and have so little lithium that it would measurably water down the other elements?
- accrual 19d agoNot an astrophysicist, but since they mentioned the lithium is depleted, I wonder if that implies the collision of a planetary body with a sun would consume or react with the solar lithium.
- gus_massa 19d agoNeither an astrophysics. I skimmed the paper. IIUC the collision with the planet mixed internal layers of the Sun and a lot of the Lithium went to the core and got fussed with Hydrogen. PS: The paper says that that actual A(Li)=1.1 instead of the expected A(Li)=3.3. I needed a lot of search to understand it until Gemini kindly liked this page. https://astronomy.stackexchange.com/questions/61814/what-do-lithium-abundance-numbers-mean-in-catalogs-like-hypatia https://astronomy.stackexchange.com/questions/61814/what-do-... A(Li)=1.1 means the Li/H ratio is 10^(-10.9) = 10^(-8.9)% A(Li)=3.3 means the Li/H ratio is 10^(-9.7) = 10^(-7.7)%
