| Description | Several important questions remain open regarding the latest stages of evolution of the most massive stars, in particular regarding the exact evolutionary paths taken between the various subtypes of O stars, LBVs and Wolf-Rayet stars, and the mass-loss history of these objects throughout their lives. In this proposal we will address these questions by extending the massive stars programme of the the MESS GTKP. In the MESS programme, we focus on the LBV phenomenon. Here we will focus on the properties of nebular ejecta from a peculiar O-type star and a Wolf-Rayet star. These together will allow us to study the relationship between these three types of related, massive, mass-losing stars, in particular to better understand how the mass loss both changes with evolutionary stage and how it may dictate the evolutionary paths taken. |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
