After discovering thousands of planetary systems orbiting other stars, we are finally at a point where we can start looking at the patterns we see to hopefully understand how they formed. But hold the phone - because maybe the configurations we see are nothing but purely random. Dynamical evolution tends to disorder initially pristine systems, so do planets even still remember how they formed? Is the ordered nature of the Solar System typical or rare? This week we dive into these questions by discussing a new research paper by Prof Kipping on the topic. ::More about this Video:: ► Kipping (2017), "Do planets remember how they formed?": https://arxiv.org/abs/1709.04987 ► GitHub repo of the microstate visualizations: https://github.com/CoolWorlds/exoinformatics ► Cake number: https://en.wikipedia.org/wiki/Cake_number ► Eulerian number: https://en.wikipedia.org/wiki/Eulerian_number ► Kepler Orrey by Dan Fabrycky: http://astro.uchicago.edu/~fabrycky/kepler/ ► Columbia University Department of Astronomy: http://www.astro.columbia.edu ► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu ► Outro music by 8-bit Universe "Harder Better Faster Stronger [8 Bit Cover Tribute to Daft Punk]": https://8bituniverse.bandcamp.com/track/harder-better-faster-stronger-8-bit-tribute-to-daft-punk ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Tabby's Star ► http://bit.ly/TabbysStar Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!
