Evidence of Galactic Interaction in the Small Magellanic Cloud Probed by Gaia-selected Massive Star Candidates

We present identifications and kinematic analysis of 7426 massive (≥8 M _⊙ ) stars in the Small Magellanic Cloud (SMC), using Gaia DR3 data. We used the Gaia ( G _BP − G _RP , G ) color–magnitude diagram to select the population of massive stars, and parallax to omit foreground objects. The spatial...
