Abstract It is proposed to study objects in their early stages of formation to investigate the intrinsic properties of these young objects and to establish the nature of their interaction with the local ISM. Time variablity of these targets is an important parameter, the targets will be revisited several times during the GTO phase. The program requires both the high-resolution, ultraviolet imaging and the long-slit spectrograph of the FOC for its success. ------------------------------------------------------------------------------------ 8.

Several targets will be revisited during the GTO period, the purpose being to study their temporal variation which is expected to give an insight into their physical nature. Hence, it would be premature, and would certainly compromise the scientific goals of the program, if their data were released before one year had elapsed after the final observation. ------------------------------------------------------------------------------------ 13.
