Season 3 Episode 9 - Ben Montet Makes a Star Weirder



Released: 8 August 2016
Duration:47 minutes 44 seconds

Ben Montet
Host Paul Carr talks to astronomer Ben Montet,who has, with his colleague Joshua Simon, just published the result that Tabby's Star (KIC 8462852) dimmed considerably over the four year course of the Kepler Space Telescope prime mission.

Guest Bio:

Ben Montet recently defended his Ph.D. at the California Institute of Technology, where his thesis work focused on understanding the properties of low-mass stars and their companions. During his thesis, he led teams which measured the occurrence rate of Jupiter-sized planets in wide orbits around low-mass stars, developed the first catalog of confirmed transiting planets from the K2 mission, and characterized the first non-inflated brown dwarf with a directly measured mass, radius, and atmospheric properties. In September, he will begin a Carl Sagan Fellowship at the University of Chicago.
