Details

Dr. Inseok Song will be hosting Dr. Russel White of the Georgia Institute of Technology this week. His talk is entitled "High Precision Infrared Radial Velocities and the Search for Young Planets."

I will present results from our on-going high-precision infrared radial velocity survey of late-type stars. Our technique achieves a record breaking precision of 50 m/s, which is finally sufficient to begin identifying planets at infrared wavelengths. Using this technique, we are surveying a sample of young (1-10 Myr) stars to search for hot Jupiters; their discovery at these ages would put much needed constraints on the planet formation and migration timescales. I will present results from this work, including newly discovered young companions and an initial assessment of the planet frequency at these ages. I will also discuss the potential for infrared radial velocities to assess more completely the planet frequency of our nearest low mass stellar neighbors.
