Discovery of a Warped Infalling Disk around an O-type YSO Alberto Sanna MPIfR, Bonn, DE
I will present the first direct imaging of an accretion disk revealed with ALMA around an O-type young stellar object. The disk appears warped and, by comparing the observed and modeled pv-plots (including full radiation transfer) along the disk plane, I will show there is a significant infalling motion towards the central star. I will finally present new ALMA dust polarization observations which unveil the magnetic field morphology across the warped disk.
