Title: The Amazing Disappearing Disk

Abstract: 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 one to two years. The cause of this depletion event is not known, but continued monitoring of the star can help identify the mechanism responsible for this rapid clearing of its inner dusty disk. We propose a T-ReCS measurement of the source to monitor its mid-infrared flux level.
