The Nearby, Young, Argus Association: Membership, Age, and Dusty Debris Disks

Understand

The reality of a field Argus Association has been doubted in some papers in the literature.

• We apply Gaia DR2 data to stars previously suggested to be Argus members and conclude that a true association exists with age 40-50 Myr and containing many stars within 100 pc of Earth; Beta Leo and 49 Cet are two especially interesting members.
• Based on youth and proximity to Earth, Argus is one of the better nearby moving groups to target in direct imaging programs for dusty debris disks and young planets.
