  Gaia EDR3 offers greatly improved kinematics for nearby objects, including
members of nearby young stellar moving groups (NYMGs). In this study, we aim to
identify low-mass NYMG members (spectral types of M0 to mid-L) in Gaia EDR3. We
calculated spatio-kinematic membership probabilities utilising a Bayesian
membership probability calculation scheme developed in our previous study. We
evaluated stellar youth primarily based on colour-magnitude diagram positions.
Combining spatio-kinematic membership assessment and youth evaluation, we
identified ~2900 low-mass NYMG candidate members including ~700 previously
claimed members. In the set of ~2200 new candidate members, ~550 appear to be
young based on NUV brightness. Our pilot spectroscopic study with WiFeS on the
ANU 2.3-m telescope observed 78 candidates, with 79 per cent confirmed as
members. Using our new member sample, we estimated an isochronal age of the
beta-Pictoris Moving Group. The mean age (~10 Myr), which is around half the
age of recent estimates, suggests either a truly younger age of the
beta-Pictoris Moving Group or inaccuracies in contemporary isochrones. As the
main results of this study, we provide lists of newly confirmed and candidate
low-mass NYMG members.
