How many single stars among solar-type stars?,etary orbits and in the context of the search for extraterrestrial life, the long period systems (say with P > 100 yrs) may be considered as two independent single systems. As they represent about half of the total of the binary systems, we may expect actually about two thirds of the solar-type stars which could accept stable planetary orbits.

Zum Konvergenzverhalten von FAP,. In a few cases the presence of a pre-planetary circumstellar disk can be inferred from an analysis of the relative velocity of forbidden lines with respect to the stellar rest velocity, but further observations are required to obtain better statistics on the presence of circumstellar disks.
