Discovering and Characterizing Exoplanets with High-Contrast Spectroscopy
Timothy Brandt
11:00am|Princeton University, Peyton Hall, Room 145
Advances in adaptive optics and infrared instrumentation now enable us to see young exoplanets millions of times fainter than their host stars. By collecting photons emitted by these worlds, imaging allows us to measure the chemistry and physical...

Climate Dynamics of Condensible-Rich Exoplanet Atmospheres
Ray Pierrehumbert
10:45am|Bloomberg Hall Lecture Hall

On the present Earth, the primary condensible substance — water vapor — represents only a few percent of the mass of the atmosphere. While the effects of the latent heat of phase change are dynamically significant, the direct effects of mass loss...

Lonely Galaxies: The Baryon Content of Isolated Dwarf Galaxies
Marla Geha
10:45am|Bloomberg Hall Lecture Hall

Environment plays a major in role in the evolution of galaxies. This is particularly true of low mass dwarf galaxies where more massive galaxies dramatically affect the local gravitational potential. Isolated galaxies offer a unique test bed for...
