Globulettes: Formation Sites Of Free Floating Planets?

NIR imaging and ALMA arc-second resolution CO, CS and H2CO imaging of two typical Rosette Nebula globulettes is discussed. Velocity structure is observed in the 12CO line whereas the observed CS line widths are are extremely narrow, 0.3kms-1-0.4kms-1, indicating practically no internal motions in the very core. The highest molecular line column densities are detected at the side facing the HII region central cluster. The estimated masses of the globulettes range from 60 to 100 MJupiter (RN88) and 100 to 300MJ (RN122) and thus formation of planetary mass free floating planets is possible.
