Aims. 60% of the A star members of the 12 Myr oldβ Pictoris moving group (BPMG) show significant excess emissi on in the mid-infrared, several million years after the proto-plane tary disk is thought to disperse. Theoretical models suggest this peak may coincide with the formation of Pluto-sized planetesimals in the disk, stirring smaller bodies into collisional destru ction. Here we present resolved mid-infrared imaging of the disk ofη Tel (A0V in the BPMG) and consider its implications for… CONTINUE READING
