On the origin of the very young groups η and ε Chamaeleontis.

JILINSKI E., ORTEGA V.G. and DE LA REZA R.

Abstract (from CDS):

The three-dimensional orbits of the kinematical centers of the η Cha and ε Cha compact groups are retraced under the action of a general Galactic potential. The results show that both groups were formed in the same spatial region about 7 Myr ago. Their birthplace appears to be quite near the Lower Centaurus Crux subgroup of the Sco-Cen OB association. The epoch of minimum separation in the past between η Cha and ε Cha turns out to be consistent with the estimated evolutionary age.
