Radio Emission of the Sun and Planets
International Series of Monographs in Natural Philosophy, Volume 25: Radio Emission of the Sun and Planets presents the origin of the radio emission of the planets. This book examines the outstanding triumphs achieved by radio astronomy of the solar system. Comprised of 10 chapters, this volume begins with an overview of the physical conditions in the upper layers of the Sun, the Moon, and the planets. This text then examines the three characteristics of radio emission, namely, the frequency spectrum, the polarization, and the angular spectrum. Other chapters consider the measurements of the intensity of the solar radio emission, which indicate the existence of a lower limit. This book discusses as well the complex phenomena of the sporadic solar radio emission. The final chapter deals with the theory of the radio emission of Venus. This monograph is a valuable resource for radio astronomers and astrophysicists who are interested in the state of investigations in galactic radio astronomy.
The Spectrum of a Local Source of Radio Emission on the Sun
The spectrum of local radio emission sources is most directly determined by simultaneous observations of several waves at a high angular resolution. Such observations of the emission of a source associated with the group of spots No. 188 (the numeration of the bulletin ''Solar Data'' (S sub p = 1076)) in the range from 0.8 cm to 30 cm were carried out during the solar eclipse on 19 April 1959. The results are shown as a graph for the ratio of the source flux F sub u, to the flux of the undisturbed sun, F sub o. Data are from the observations of the joint expedition of the AN SSSR and the AN KNR and from observations in Japan. (Author).

Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de voted 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, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 18 contains literature published in 1976 and received before March 1, 1977; some older liter ature which was received late and which is not recorded in earlier volumes is also included.
