[Baps] MIT/EAPS DLS speaker on origin of meteorites

[Julien de Wit]

Good morning BAPS,

Today, I am writing to bring to your attention this week's DLS speaker Miroslav Brǒz.
If you loved the movie Don’t Look Up and/or are eager to learn more about meteorites and how objects from out of space end up here on Earth (as asteroid 2024YR4 is now all over the news), please join us for Mira’s talk in 54-100 at noon on Wednesday Feb 12th.

Mira’s work was notably featured on Nature’s cover in October<https://www.nature.com/nature/volumes/634/issues/8034> and again last week.

Talk title: "On the origin of meteorites. Why Nature^1 tricked us for so long?”
^1 Not the journal.

Abstract: "The ordinary chondrite meteorites comprise 70% of all falls. Hereinafter we explain their origin as ejecta from three relatively recent collisions in the asteroid belt — related to the Massalia Koronis and Karin asteroid families. Our conclusions are supported by various kinds of observations ranging from reflectance spectroscopy of near-Earth asteroidsinfrared photometry of dust bands radiometric dating of meteorites to bolide orbits prior to atmospheric entry.”

More about Mira: "Miroslav Broz works as the assistant professor at Charles University in Prague, Czech republic. He studied celestial mechanics, including the role of non-graviational forces acting on meteoroids. His recent studies focus on formation of planetary systems, asteroidal satellites, and corresponding numerical modelling of collisions. He collaborated on the ESO Large Programme devoted to adaptive-optics observations of asteroids with the Very Large Telescope.”

I’ll add to this that Mira has also worked on a range of planetary-stellar-astronomy projects, so if you’re interested in meeting with him that might be possible => contact me.
I’ve heard that he is notably looking to discuss aspects of the core-mantle boundary, habitability and exoplanet characterization, (paleo)climate and the effect of extraterrestrial dust.

Thank you and best wishes,

Julien
