Scientific paper

We have identified a nearby young star that went from hosting a densely populated dust disk in its terrestrial planet zone to hosting a meager warm dust disk in the period of only one to two years. We will discuss observations of this system that led to this remarkable finding and will suggest mechanisms that could act to rapidly deplete a dusty disk.
Funding for this research came from NASA grants to UCLA and University of Georgia, an LLNL-Minigrant to UCLA, from the Spitzer Visiting Graduate Student Program, and from the NSF through award No. AST-1003318.
