Look out - it’s the attack of the planet-eating #suns! Enter Lorenzo Spina from Italy’s Astronomical Observatory of Padua and colleagues. They studied the #chemical composition of over 100 pairs of #stars! #astronomy @lorenzospina

#Radio 📻. Hoy en @PMovimiento de @RadioUNAM hablaré con @berenice_wav y @mquemain sobre #estrellas que comen #planetas. Basado en un artículo de @lorenzospina y colaboradores. 🔔. ¡No te lo pierdas! 🔔 [Crédito de la imagen: NASA/ESA/G. Bacon]

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: https://t.co/nGwof6oQZ9

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 (https://t.co/NoMrNyrPBT), 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 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:

How are the so-called lithium-rich giants formed?

A new @GaiaESO paper, recently accepted for publication in @AandA_journal, investigates this puzzle that has been bothering astronomers for almost 40 years now.

@adamspacemann @EricMamajek Thanks @adamspacemann ! I really enjoyed chatting with you and reading this piece

[Lorenzo Spina @lorenzospina]

@beckyferreira Amazing piece!!! Thanks @beckyferreira

[Becky Ferreira @beckyferreira]

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

Astrônomos encontram estrelas que devoraram planetas. A pesquisa tem participação do Prof. @DrJorgeMelendez (IAG/USP).

Estudo aponta que pelo menos uma em quatro estrelas semelhantes ao Sol engolem os planetas que as orbitam (via @futuroastronomo):

A quarter of Sun-like stars in binary systems show evidence of having devoured their planetary progeny, say @lorenzospina et al. https://t.co/W3tNPCRWYq
