    Astronomy Colloquium: Daniel Lin

    Institution: Jansky postdoctoral fellow, NRAO Title: Tracking the Grist and Flakes of Planetesimals with Dust Polarization Abstract: How planetesimals form and evolve in circumstellar disks is one of the most important questions in astrophysics. In this talk, I will demonstrate that polarization is a unique tool for studying the properties of dust grains throughout the …

    Astronomy Colloquium: Daniel Proga

    Institution: University of Nevada-Las Vegas Title: Multiphase Supersonic Outflows in Active Galactic Nuclei Abstract: Large-scale mass outflows from Active Galactic Nuclei (AGN) naturally connect  a galaxy to its central black hole and enable an AGN feedback mechanism. However, quantifying the feedback efficiency is challenging because it involves considering  multidimensional fluid dynamics, radiative processes, magnetic processes, …

    Astronomy Colloquium: Eric van Clepper

    Institution: WiCOR, UW-Madison Title: Modeling the Chemical and Dynamic Feedback Mechanisms of Planet Formation Abstract: Planets form in protoplanetary disks, inheriting the composition of the solids and gas present at their formation location. These PPDs, however, are constantly evolving, with dust growth, fragmentation, and pebble drift driving chemical evolution in the gas. While these effects …

    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: 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 …
