SCIENTIFIC ABSTRACT This proposal sets out a plan for observations of the driving sources for Herbig-Haro (HH) flows, using both ISOPHOT-P and ISOPHOT-C to obtain maximum wavelength coverage. With the help of sub-mm observations, vital information on the evolution of disks around low-mass objects and their role in the mass loss phenomena can be derived. OBSERVATION SUMMARY It is intended to perform broad band photometry on the energy sources with a variety of filters, but ensuring that there is always enough sky to allow background subtraction. In order to achieve 5% photometry, the minimum integration time per filter should be 32sec. This has, therefore, been selected as the standard integration time. With the PHT-C detector a one-dimensional scans will be made at 200um, adding new science, possibly never again achievable.
