Profile: Prof. Robert Gehrz

I'm enthralled by dirt -- at least the astronomical kind. The dust out of which our planet formed, originally came from the stars. For many years, I have been studying the conditions under which this dust condenses out of hotter gases. Novae, for example, are stars that undergo non-fatal explosions that expel enormous amounts of dust into space. I have played major roles in the decades-long planning and development of the Spitzer Infrared Telescope, now bringing us spectacular images of our dusty space environment. I am looking forward to using the infrared-optimized LBT to study dust in interesting systems such as the RY Scuti binary system, with two stars orbiting each other so closely that they touch.
