Planetary Science Seminar

Towards Radio Detection and Characterization of Exoplanets
Alex Wolszczan, Evan Pugh Professor of Astronomy and Astrophysics, Department of Astronomy & Astrophysics, The Pennsylvania State University

I will discuss the ongoing Arecibo programs to detect flaring radio emission from the coolest brown dwarfs and giant exoplanets, and to monitor radio activity of M-dwarf targets of the upcoming near-infrared, Habitable Planet Finder survey with the Hobby-Eberly Telescope. In particular, I will present the most recent detections of flares from two T-type brown dwarfs, which suggest that the same should be possible for hot, young exoplanets such as the relatively nearby HR 8799 system. I will also discuss the results of one year long monitoring of an M9-star, TVLM 513-46546, used as a proxy for the design of our M-dwarf monitoring project.
