This book was released on 1960 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: From recent rocket monochromator measurements of solar photon fluxes phi(lambda) between 1300 and 60 A around 200 km, the fluxes phi sub o characteristic of the upper F sub 2region and interplanetary space near the earth are estimated by assuming some reasonable spectral attenuation factors phi/phi sub o because of the atmospheric absorption above the point of observation. Ionization rates in terms of sigma sub j phi sub o are estimated for H, O, N, and N2. The estimated total ionization rate for the hydrogen atom of about 5 x 10 to the -7th power per sec implies a fractional ionization of at least 99.9% for total hydrogen particle number densities of less than about 500 per cc.

This book was released on 2006-06-30 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the history of science the opening up of a new observational or experimental window is always followed by an increase in knowledge of the subject concerned. This is also the case with the subject of this book, ultraviolet radiation (hereafter UV). In principle, the ultraviolet range might be just one more of these windows, of no particular importance. However, the energy per UV photon provides the main peculiarity, its magnitude being great enough to produce important ch- ical reactions in the atmospheres of planets and satellites, thereby a?ecting the transmission of this radiation to the ground. The Sun is the main natural source of UV radiation in the Solar System and our planet is the body where its in?uences can be best tested and the only one where its relation with life can be studied. However, the terrestrial atmosphere blocksmostofthephotonsinthiselectromagneticrangeandastronomershavehad to develop various techniques (balloons, planes and rockets) to cross this barrier and access the information. These tools have been used in parallel to investigate the physical properties of the terrestrial atmosphere and the interaction of its constituents with light. This book will addresses most of these topics.

Download or read book A Guide to the Solar Corona written by Donald E. Billings and published by Academic Press. This book was released on 2013-10-22 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Guide to the Solar Corona is specifically directed to the space scientist or engineer who is not a specialist in solar physics, but whose work requires a fairly detailed knowledge of the corona. It is hoped that the material may prove useful to most graduate students in astrophysics, while solar physicists may find some topics of interest and value to them. The book contains 12 chapters and begins with three descriptive chapters that provide the casual reader with a concept of the corona as it is evident through more or less direct observation. Topics covered include the development of coronal science, observational techniques, and observational aspects of the corona. The next chapter discusses methods of analyzing coronal data. Subsequent chapters present theoretical considerations as they are applicable to the corona. These combine theory with observation to provide a description of the various aspects of the corona. The final chapter is a combination of established ideas and speculation on the place of the corona in the universe.

Download or read book The Solar Spectrum written by C. de Jager and published by Springer. This book was released on 2013-11-11 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: A good deal of our information on solar physics and on solar phenomena is derived from the solar spectrum. A quantitative interpretation of this spectrum was only possible after 1920, after the establishment of Bohr's atomic model, the discovery of Saha's law, and the development of spectrophotometry. The resolving and light gathering powers of our instruments have greatly increased since. We have seen an enormous progress in our theoretical under standing of basic atomic phenomena, and of the intricate problems concerned with the transfer of energy through a complicated structure like the sun's outer layers. In particular the observable part of the solar spectrum tremen dously enlarged since the introduction, in the years after 1945, of radio astronomy, enabling us to study the solar spectrum between wavelengths of some mm to about 15 m, of space research, giving access to the whole electro magnetic spectrum below 3000 A, down to about 0. 01 A. Further, the low and high energetic components of the solar particles spectrum have been dis covered with space probes (the solar wind), rockets, balloons (the so-called sub cosmic-ray particles) and cosmic ray monitors (solar cosmic ray bursts). The extreme wealth of this spectrum, much vaster in extent than the earlier investigators could only dream of, is an important source of information. It looked appropriate to us, after the rapid development of this branch of science, ' to invite the world's leading solar physicists to Utrecht for a summa rizing symposium on the whole solar spectrum.

Available in PDF, EPUB and Kindle. Book excerpt: 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. I, 1980; some older Volume 27 contains literature published in 1980 and received before August literature which was received late and which is not recorded in earlier volumes is also included. We acknowledge with thanks contributions to this volume by Dr. J. Bouska, Prague, who surveyed journals and publications in Czech and supplied us with abstracts in English.
