χ1 Fornacis cluster
The χ1 Fornacis cluster, or Alessi 13,[3] is one of the four star clusters known within 110 parsecs from Earth. [2] Despite its closeness, the χ1 Fornacis cluster has barely been studied. Its age is 40 million years and its distance is 104 parsecs.[2] The χ1 Fornacis cluster appears to be closely related to the Tucana–Horologium and Columba associations.[2] A remarkable, unprecedented aspect of the cluster is the large percentage of M-type stars with warm excess infrared emission due to orbiting dust grains.[2]
