Observation with the
Spitzer Space Telescope reveals what appears to be an
excess infrared emission from this star. This suggests the presence of circumstellar material in this system, making it a
debris disk candidate.[10] This star may be a member of the
Beta Pictoris moving group, an association of about 17 stars that share a common origin and a similar motion through space. If it is a member of this group, this would put the age of β TrA at about 12 million years; the same as the group itself.[11]
