Astrophysics Luncheon Seminar Atmospheric Models at the Onset of Next-Generation Telescopes Presented by Natasha Batalha University of California, Santa Cruz Monday, May 6, 2019 12:00 noon in 169-336 and on Webex Abstract Across all the state-of-the-art pipelines that exist to study atmospheric composition and climate from exoplanets, about half a dozen have been developed for transiting science, a few of which are open-source. On the other hand, for observations of reflected light from directly imagined exoplanets there have only been two, neither of which are open source. With the detection and analysis of reflected light from optical phase curves and optical photometry and the onset of reflected light direct imaging missions on the horizon, such has WFIRST and ELTs, there has been an increasing demand for an accessible, versatile reflected light code. I will present the first open-source radiative transfer model for computing the reflected light of exoplanets at any phase geometry, called PICASO: Planetary Intensity Code for Atmospheric Scattering Observations. I will also describe key steps I am taking towards making tools like PICASO more accessible. Specifically, I will focus on a proposed pipeline that I am developing to increase the accessibility of critical opacity data. I will conclude by describing the ways in which I have leveraged this framework in conjunction with an information content analysis to inform WFIRST mission design studies.
