A remarkable method in astronomy uses transiting exoplanets to measure the average density of the parent star. By comparing this value to other ways of measuring a star's density, astronomers can learn more about the planet, such as its orbital shape. Prof Kipping breaks down how this is possible in a simplified way and explains how "Asterodensity Profiling" is becoming an important tool in astronomy. ::More about this Video:: ► Cartoon list of Asterodensity Profiling effects: https://www.cfa.harvard.edu/~dkipping/AP_Cheat_Sheet.pdf ► Kipping (2014), "Characterizing Distant Worlds with Asterodensity Profiling": http://arxiv.org/abs/1311.1170 ► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk ::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 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!!
