  • Monday, July 13, 2020
    Princeton University Exoplanet Discussion Group
    “A Stellar Age Dependence of the Planet Radius Gap”

    Location: Virtual Meeting
    Time: 12:15 PM
    Speaker(s): Travis Berger, University of Hawaii
    Note:

    Josh Winn is the organizer.



    Description: A major bottleneck for Kepler exoplanet demographics has been the lack of precise properties for most of the observed stars. In this talk, I will present the first homogeneous and precise characterization of all Kepler targets using Gaia DR2. Applying these improved stellar parameters to revise exoplanet properties, I will present the dependence of the planet radius gap on stellar mass and age for the full Kepler exoplanet sample and discuss implications for the competing theories of core-powered mass-loss and photoevaporation. In particular, I will present first evidence for the planet radius gap's dependence on stellar age on timescales of a Gyr, a result that is only predicted by core-powered mass-loss. In addition, I will show that low-flux sub-Neptunes appear to shrink on Gyr timescales, suggesting that most of these planets possess H/He envelopes that measurably contract over Gyr timescales as opposed to higher mean molecular weight atmospheres. Finally, I will reveal that there are bona-fide planets within the "hot sub-Neptunian desert" and show that these planets are preferentially orbiting more evolved stars compared to other planets at similar incident fluxes. The results detailed here demonstrate the potential for transformative characterization of stellar and exoplanet populations using Gaia data.

  • Tuesday, July 14, 2020
    Princeton University 2020 Summer Colloquium Series
    “Promoting Diversity and Addressing Barriers in Physics”

    Location: Virtual Meeting
    Time: 11:00 AM
    Speaker(s): Geraldine Cochran, Rutgers University
    Note:

    The Summer 2020 Colloquium Series is led by Jenny Greene.



    Description: In this presentation, I will discuss the ways in which physicists have engaged in diversity work over the past twenty years. I will analyze these methods using a critical framework. I will then discuss efforts to address barriers to diversity in physics graduate programs by discussing the results of two research studies on graduate education in physics.
