Exploring New Worlds

Presenter: Daniel Apai, University of Arizona
When: March 25, 2013 11AM PDT

Astronomy has entered an exciting new era where ground- and space-based observatories open windows on planetary systems increasingly similar to our own. I will discuss observational techniques, direct imaging and planetary transits, that allow us to characterize the atmospheres of extrasolar planets and, in the near future, to search for biosignatures. I will show results from a new observing technique, rotational phase mapping, that provides an exciting look into the atmospheres, clouds, and surface features of exoplanets and ultracool brown dwarfs. Finally, I will discuss possible pathways toward characterizing habitable planets and searching for biosignatures in their atmospheres.
