Science Under the Stars: How do the planets form?

Join us in the Planetarium for this free talk with Dr. Aida Behmard, of the American Museum of Natural History. How can we understand the processes that formed the thousands of planets we’ve discovered orbiting other stars? We can look at the stars these exoplanets orbit themselves, because the characteristics of these host stars - like what they’re made of - encode clues on how their planets came to be.

Dr. Behmard combines techniques used for studying exoplanets with another area of astronomy - galactic archaeology, which treats the chemistry of stars as artifacts for reconstructing the history of our galaxy, the Milky Way. By looking at exoplanet host star chemistry in galactic archaeology datasets, we can begin to understand planet formation on large - even galactic - scales.
