    Panning for gold with things that go bang in the night

    Abstract: Electromagnetic follow-up observations of the gravitational wave-detected binary neutron star merger (NSM) GW1701817 suggested that material ejected from the accretion disk formed in the merger underwent a robust r-process nucleosynthesis, producing heavy elements like Au, Pt, and Eu. These observations seemed to answer a long-standing question about the origin of the heaviest elements in the Universe. However, the conditions that characterize the disks formed in NSMs are also found in other systems,...

    The precessing gas rings around WD1145+017

    Abstract: Approximately 30% of white dwarfs are polluted by metals, the result of accretion onto the stellar surface by rocky bodies that have been tidally disrupted. These systems thus offer a direct window onto the interior composition of rocky planetesimals. Disks of these metals are also observed in emission around a subset of polluted white dwarfs from which the radial extent of the orbiting gas has been determined. The (so far) geometrically-unique polluted white dwarf WD1145+017 provides a different perspective on the gaseous...

    Finding and characterizing the youngest exoplanets 

    Abstract: Observing and characterizing newly-formed planets around young stars is fundamental for developing planet formation and evolution theory.  In this talk, I will present results of an infrared radial velocity survey with the primary goal of detecting exoplanets around the youngest stars using the Immersion Grating Infrared Spectrograph (IGRINS) on Lowell Observatory's 4.3-m Discovery Channel Telescope (DCT). For one young planet, CI Tau b, I will present IGRINS observations where we have searched for...

    Journey to the Center of the Super-Earth

    Sub-Neptune, super-Earth size exoplanets are a new planet class. Though absent from the Solar System, they are found by microlensing, radial velocity, and transit surveys to be common around distant stars. In this talk, I'll review both recent developments and outstanding puzzles in our understanding of the nature and origin of these enigmatic planets.
