A quest for rotating disks in high-mass star forming regions

We present ALMA observations towards two high-mass star forming regions. These reveal extended filamentary structures fragmenting into a number of dense cores. The detection of a multitude of lines from complex molecular species permits to study the physical and kinematic properties of three dense cores. Signposts of Keplerian rotation are identified and suggest the presence of disks rotating about stars with masses 4–18 M⊙. These results likely confirm that B-type stars form via disk-mediated accretion, and set the stage for the quest for similar structures toward the most massive O-type stars.
