      Dr. Kaitlin Kratter -- Building a Solar System on the Computer
      Dec 1 2025

      How did our solar system form? More generally, how does any solar system form? We get some of our answers to these questions by looking at newly-forming planetary systems in the first million years of their lives. But getting a complete picture also requires a lot of theoretical work, understanding each stage of solar system formation, which often entails big computational models of the early solar system. Dr. Kaitlin Kratter is a leader in the practice of building these big models and using them to improve our understanding of how the planets first formed.

    • Dr. Tim Cunningham -- White Dwarfs Sometimes Eat Planets

      Dr. Tim Cunningham -- White Dwarfs Sometimes Eat Planets
      Nov 1 2025

      A white dwarf star is the compact, dense remnant of a once-thriving solar system. Long after the original star has died and turned into a white dwarf, it can still interact with its solar system. We can even see white dwarfs eating up the rocky debris that once made up their solar system, and apparently making sense of all of this requires a detailed understanding of how convection works in these dead stellar remnants.
