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.
