Probing the low-mass stellar end of the η Chamaeleontis cluster.

Abstract (from CDS):

We have identified three faint new members of the η Chamaeleontis cluster. Spectral types of the new members are estimated to be ∼M5, based on their TiO band strengths and broadband colors. With an age of 5-8 Myr for the cluster, masses of these new members are estimated to be ∼0.08 M☉. All three display strong Li 6708 Å absorption and Hα emission features, including one with an Hα emission equivalent width of ∼60 Å, along with He I 6678 and 7605 Å emission features that are characteristics of classical T Tauri stars.
