Subject: A Search for Dust in the Habitable Zones Around Solar-like Stars
Refreshments served following the talk in the Astronomy Reading Room, 358 Physics
As part of a program to search for and characterize the presence of warm dust in the habitable zones around nearby solar like stars, we have search for dust within a few AU of the central stars. We have observed 152 FGKM stars with the Spitzer short-low and long-low IRS modules, and using the FLUOR instrument on the CHARA interferometer, we have observed the main sequence A stars beta Leo and zeta Lep, which are known to have a debris disk. I will present an overview of our results.
