The iPLEX Spring 2017 Guest Speaker Schedule

Posted on Mar 31, 2017 in Seminars

The iPLEX Spring 2017 Guest Speaker Schedule:

Please join us on Fridays from 12 to 1pm in UCLA Geology Building (Room 3-814), followed by lunch 1 to 2pm.


Apr 07: Jessie Christiansen (Caltech/JPL) – Taking the Galactic Exoplanet Census

Measuring the occurrence rate of extrasolar planets is one of the most fundamental constraints on our understanding of planets throughout the Galaxy. By studying planet populations across a wide parameter space in stellar age, type, metallicity, and multiplicity, we can inform planet formation, migration and evolution theories. The NASA Kepler mission was a space-based survey for transiting exoplanets, primarily focussed on measuring the occurrence rates of Earth-like planets orbiting Sun-like stars. I will describe our ongoing efforts to catalogue the exoplanets in the Kepler field, including characterizing the survey completeness and reliability, and summarize our progress towards measuring robust occurrence rates. I will also describe the opportunity afforded by the NASA K2 mission, the successor to the Kepler mission, to expand occurrence rate calculations into a wider stellar parameter space.

Apr 14: Joseph O’Rourke (Caltech) Generating Magnetic Fields in Earth, Venus, and Super-Earth Exoplanets

Earth’s global magnetic field has survived for at least 3.5 billion years, yet Venus lacks a dynamo today. I will explore possible explanations for this dichotomy and discuss related implications for the internal structure and evolution of massive, rocky exoplanets.
