Hannelore Goos earned her astrological armor in the former "Astrologischen Arbeitskreis" in Frankfurt, her teachers being among others Manfred M. Herm, Edith Wangemann and Bernd A. Mertz. An extensive literature study supplemented lectures and seminars. Since 2001, she deals mainly with astrological basic research, in particular the doctrine of signatures. The result of this work is published since 2002 as "Lexikon der astrologischen Zuordnungen" (Rulership book) which has now become a standard work in German-speaking countries. As Hannelore Goos has not only learned her native language German, but also Latin, English, French, Swedish and Dutch, the input for this 4-volume astrological dictionary was found in the important sources of all these languages. In 2010 the second, expanded edition has been published. Further research topics were
- the question of a relationship between length of life and sun sign,
- the astrological interpretation of the 1977 discovered Chiron and
- the representation of the meaning of names by means of astrological symbols.
All projects have been completed with the publication of a book.
A research concerning the difference between the Latin planet names and the usually reported Greek mythology for their explanation led to a thorough engagement in Roman history, mythology and religion.
