From page 18...
... The primely initial goals are to confirm the presence and frequency of, or limit the existence of, extrasolar planets in the Jupiter- to Uranus-mass range, and to study the dynamics of discovered systems. 1b achieve these goals requires the following: · Development of instrumentation to enable sensitive search techniques, and application of these techniques to a stellar population sufficient)

From page 19...
... This general goal requires both new theoretical comparisons among such systems and related laboratory experiments, including considerations of the following: · Companion of low-mass stars, substellar objects, and planets and the differences and similarities of their formation conditions; Various types of binary systems and plan eddy systems and the relations among them; · Fragmentation of a collapsing and rotating assemblage into multiple objects and their subsequent evolution; · Physical and chemical characterization of stellar nebulae through time, silicate-carbon dust grains and icy-organic Gain mantles, the precipitation of solid matter from cooling nebular gas, He conditions under which dust paroles and planetesimals accrete or erode, and the evolution of accretion
