Proper motion vectors of Tr-37 members @ GAIA
|
In a recent work, using Gaia-DR3 data and machine learning tools, we identified members of Tr-37 young cluster
over 7.1 degree^2 area. Doing kinematic analysis, we find that cluster members are expanding at a rate of 1.1 km/s,
which is found to be slower compared to the expansion velocity, ~5 km/s, of the molecular gas in the complex.
We discussed that this slow expansion of the cluster is likley due to the fact that most of the cluster members are
still bound and the cluster is still not significantly dynamically evolved. For details, see Das et al. 2023.
