Speaker Schedule

  • Oct 22
    Astronomy Colloquium: Stella Ocker

    Institution: Brinson Prize Postdoctoral Fellow, Caltech Title: Probing Cosmic Plasmas from Sub-AU to Gigaparsec Scales Abstract: Most of the ordinary matter in the universe takes the form of diffuse ionized gas, or plasma. Characterizing the full distribution of this plasma is critical to understanding how the universe forms its main structures. In this talk, I …

    Astronomy Colloquium: Sarah Millholland

    Institution: MIT Title: Migration, Tides, and the Diversity of Extrasolar Worlds Abstract: Many exoplanetary systems contain planets orbiting close to their host stars, with orbital periods of only days to weeks. These planets experience strong tidal forces that can reshape both their orbits and their interiors. Energy dissipation by time-dependent tidal deformations can drive orbital …

    Astronomy Colloquium: Laura Kreidberg

    Institution: Director, Max Planck Institute for Astronomy Title: Copernicus Revisited: is the Earth special? Abstract: Nearly 500 years ago, Nicolas Copernicus published his disruptive theory that Earth is not the center of the universe. This “Copernican demotion” has held fast over the centuries, as astronomers have learned that there is nothing particularly remarkable about Earth …

    Astronomy Colloquium: Anju Panthi

    Institution: Birla Institute of Astrophysics, India Title: Study of Exotic Stellar Populations in Open Clusters and Galactic Fields Abstract: Binary interactions can significantly alter stellar evolution, producing exotic populations that cannot be fully explained by single-star evolution. In this talk, I will present a multi-wavelength study of blue straggler stars (BSSs), yellow straggler stars (YSSs), …

  • Dec 10
    Astronomy Colloquium: Adina Feinstein

    Institution: Michigan State University Title: The Early Evolution of Exoplanetary Systems Abstract: Within the past decade, we have discovered only a dozen young (< 300 Myr) short-period exoplanets, compared to the ~6,000 mature systems. The radii of these young planets are larger than older planets on similar orbital periods. The leading hypothesis is that these young planets have inflated …
