Job design and industrial democracyd nearby stars. The astrometric study of a parent star of a planetary system will lead to an accurate determination of its distance. The distance is inversely proportional to the magnitude of the annual parallactic motion. The same study yields the major characteristics of the individual bodies with

On the feasibility of extra-solar planetary detection at very low ratio frequencies,e processes, is observed to come from the Sun and a number of stars smaller and cooler than the Sun, those that are known to have a magnetic field..The intensity of the planetary radiation is high enough to be detectable, in a reasonable range of distance, with a large but feasible low-frequency rad
