I'll give a review on "Planet Signatures on the Chemical Composition of Stars" at the @ESO workshop 'The Star-Planet Connection'. Registration until 20/September: eso.org/sci/meetings/2…

How much did accreted stars contribute to the build-up/shape of the Milky Way? We all found many accreted stars via their distinct orbits thanks to @ESAGaia. In our latest study (arxiv.org/abs/2109.04059), we identify/“tag” accreted stars via their chemistry with @galahsurvey. 1/5

Who knew that a quarter of Sun-like stars eat their own young? Incredible work by @lorenzospina (formerly @MonashAstro) & colleagues using @ESO #HARPS observations of more than 100 binary stars.
The Conversation - Australia + New Zealand@ConversationEDU

In the search for alien worlds that may contain life, astronomers have found at least a quarter can be ruled out. That's because they have very chaotic histories, writes @MonashUni's Lorenzo Spina. bit.ly/3Dsg8m1

The second paper this week on planet engulfment in widely separated binaries! This time the 1st author is my former PhD student Jhon Yana Galarza @ramstojh. Look at the huge difference in lithium (1 dex) for twin stars (Δ temperature < 25 K). Paper: arxiv.org/abs/2109.00679

Yet another reason to be grateful that we live in a fairly calm solar system: some 20 to 35% of Sun-like stars eat their planets. These acts of "planetary ingestion" could “drive a generational advancement in astrophysics” says a team led by @lorenzospina vice.com/en/article/wx5…
