There will be a reception with refreshments at 3:30 PM in the lounge. All interested persons are cordially invited to attend.


We are well into the Age of Exoplanets with approximately 4000 confirmed to date.  Efforts in exoplanet characterization have led to some very precise determinations of planetary densities, compositions, and even accurate maps of active region and spot locations on stellar surfaces.  Exoplanet magnetic fields, however, remain elusive.  While radio observations continue to push into the low-mass brown dwarf regime, no emission from a planetary-mass object has been confirmed.

I will discuss some of our efforts involving alternate methods for probing exoplanet magnetic fields and how they stack up so far against the prospects for detection via radio emission.
