Abstract:
We present a search for stellar members of young associations within
150pc of the Sun, based on TGAS and an updated version of the BANYAN
Σ software to determine Bayesian membership probabilities that
includes Gaia-2MASS color-magnitude diagrams. We identify 32 new
F0-M3-type bona fide members of the 10-200Myr old Sco-Cen, Carina,
Tucana-Horologium, Columba, and Octans associations and the
AB Doradus, β Pictoris, and Carina-Near moving groups. These new
bona fide members have measurements of their full kinematics and
literature data consistent with a young age. We also confirm the
membership of 66 previously known candidate members using their
Gaia-Tycho trigonometric distances or new literature radial
velocities, and identify 219 additional new candidate members, most of
which do not yet have a radial velocity measurement. This work is the
first step toward a completeness-corrected survey of young association
members based on Gaia DR2 in the near future.

for the bona fide members of young associations compiled in
Gagne+ (2018, J/ApJ/856/23) (colored circles on Figure 3). The 27
young associations were grouped in three age categories which were
found to follow distinct sequences in this particular color-magnitude
diagram. See Section 2 for more detail.
