First enlargement within 1000 AU of a massive YSO
Max-Planck-Institut für Radioastronomie, Auf dem Hügel 69, 53121 Bonn, Germany
We presented a comprehensive view, from scales of 0.1 pc down to 100 AU, of the gas dynamics driven by a massive young stellar object (YSO) in the star-forming region G023.01−00.41. Toward this region, we conducted both: 1) sub-arcsecond and high sensitivity Submillimeter Array (SMA) observations of different (e.g., CO, SiO, CH3CN, and CH3OH) molecular lines (Sanna et al. [2]), and 2) multi-epoch Very Long Baseline Interferometry (VLBI) observations of both H2O and CH3OH masers (Sanna et al. [3]). In particular, these VLBI observations allowed us to reconstruct, for the first time, both the 3D gas kinematics and magnetic field morphology in the vicinity (<1000 AU) of a massive YSO (Sanna et al. [1]).
