Scientific paper

We propose a project to map the compact dust continuum emission in a sample of 12 massive young stellar objects. The unresolved dust core emission is suspected to arise from an accretion disc or dense torus. The distance-limited sample of targets will be selected from the Red MSX Source (RMS) survey and span an order of magnitude in luminosity. We will examine whether the dust core mass scales primarily with luminosity for these objects or whether it also depends critically on other parameters such as age. The RMS survey has recently delivered the first derivation of the lifetime of the MYSO phase as a function of luminosity. These observations are essential groundwork proir to extension to larger samples, resolution of the discs and molecular line studies.
