Content

Spatially resolved molecular line observations have revealed circumstellar disks in Keplerian rotation around young stellar objects with masses up to 30 $M_\odot$. Line emission observations have been crucial in identifying and characterizing these disks and have allowed us to study their dynamics. In this contribution, I will discuss their properties and evolution and compare them to the circumstellar structures around lower mass counterparts. Particularly, I will discuss the mass accretion of disks as a function of stellar mass and time to get insights into the universality of star-formation models.
