The authors report on ALMA observations of continuum and molecular line emission with 0.′′4 resolution towards the high-mass star-forming region G35.20­0.74 N. Two dense cores are detected in typical hot-core tracers, such as CH3CN, and they reveal velocity gradients. In one of these cores, the velocity field can be fitted with an almost edge-on Keplerian disk rotating about a central mass of ~ 18 solar masses.
