Scientific paper
Hot cores attract attention because of their bright emission line spectra, but their importance in the massive star formation process makes them key sources to study. It is thought that hot cores may be the next generation of massive stars, so understanding their origins, their effect on the surrounding environment, and their future is vital to understanding massive star formation. We present high resolution millimeter observations of two well-known hot cores, G34.26+0.15 and G31.41+0.31, illustrating positional offsets of emission from different molecular species. We compare our observation with the models of Millar etal (1997). We suggest that external heating by the nearby UC HII region is a viable mechanism to produce hot core emission rather than internal heating by forming stars. Millar, T. J., Macdonald, G.
