Predicting the Masses of Seven Thousand Exoplanets (2017x25)

Air date: Jun 08, 2017

We now know of thousands of exoplanet candidates discovered by NASA's Kepler Mission, using the so-called transit method. Unfortunately, transits only tell astronomers the size of the planet, not the mass. Cool Worlds Lab member Jingjing Chen discusses her new research paper which applies a type of forecasting model to predict planetary masses, based off their sizes. This reveals a couple of strange observations, as Jingjing explains in this video. ::More about this Video:: ► Chen & Kipping (2017b), "Forecasted masses for seven thousand KOIs": https://arxiv.org/abs/1706.01522 ► Chen & Kipping (2017a), "Probabilistic Forecasting of the Masses and Radii of Other Worlds": https://arxiv.org/abs/1603.08614 ► Cool Worlds - Classifying Worlds: https://www.youtube.com/watch?v=sp28ZN9Zhdw ► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu ► Columbia University Department of Astronomy: http://www.astro.columbia.edu ► Background music by Thomas Bergersen "Final Frontier": http://www.thomasbergersen.com ::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!!
