Preface

Astronomy and Astrophysics Abstracts. which appears in semi-annual volumes, is devoted to the re­cording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970).

Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com­pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user.

Volume 3 contains literature published in 1970 and received before August IS, 1970; some older lite­rature which was received late and which is not recorded in earlier volumes is also included.

The authors of papers who have sent us abstracts on request have effectively contributed to the suc­cess of our service. We should like to express our gratitude to them. We acknowledge with thanks con­tributions to this volume by Dr. J. Bouska, who surveyed journals and publications in the Czech lan­guage and supplied us with abstracts in English, by Dr. B. Onderli~ka, Brno, for providing English ab­stracts of Russian papers, and by the Commonwealth Scientific and Industrial Research Organization (C.S.I.R.O.), Sydney, for providing titles and abstracts of papers on radio astronomy.

Our warmest thanks also to the ladies of our editorial office, Mrs Monika Betz, and Mrs Utta-Barbara Stegemann, who typed the text of this volume on IBM 72 Composers and compiled the pages from abstract slips in a perfect form for offset reproduction, and to Miss Gisela Nollert, for punching all the material for author index and subject index.
