The Heliosphere at Solar Minimum and Beyond by COSPAR. Scientific Commission D. D0.2 Symposium Pdf

Paperback. The Heliosphere is the large volume of space dominated by the expanding solar atmosphere. Even the most distant spacecraft, now at more than sixty Astronomical Units (1 Astronomical Unit = 150 million kilometers) from the sun, have yet to encounter the boundary between the Heliosphere and interstellar space. This publication contains 30 papers, reporting observations made throughout the Heliosphere and presenting theories to explain these observations. The results of the Ulysses spacecraft mission, the first to explore the Heliosphere over the solar poles, are summarised. Modulation of the galactic cosmic radiation and energetic solar particles by heliospheric structures is discussed. New results on the anomalous component of cosmic radiation are given, and predictions are made as to where the boundary of the Heliosphere may be found.

The Heliosphere through the Solar Activity Cycle by A. Balogh,Louis J. Lanzerotti,Steve T. Suess Pdf

Understanding how the Sun changes though its 11-year sunspot cycle and how these changes affect the vast space around the Sun – the heliosphere – has been one of the principal objectives of space research since the advent of the space age. This book presents the evolution of the heliosphere through an entire solar activity cycle. The last solar cycle (cycle 23) has been the best observed from both the Earth and from a fleet of spacecraft. Of these, the joint ESA-NASA Ulysses probe has provided continuous observations of the state of the heliosphere since 1990 from a unique vantage point, that of a nearly polar orbit around the Sun. Ulysses’ results affect our understanding of the heliosphere from the interior of the Sun to the interstellar medium - beyond the outer boundary of the heliosphere. Written by scientists closely associated with the Ulysses mission, the book describes and explains the many different aspects of changes in the heliosphere in response to solar activity. In particular, the authors describe the rise in solar activity from the last minimum in solar activity in 1996 to its maximum in 2000 and the subsequent decline in activity.

The Heliosphere Near Solar Minimum by Andre Balogh,Richard G. Marsden,Edward J. Smith Pdf

On the Ulysses mission scientists gathered observations from the unexplored regions of the heliosphere. This book presents a highly readable and concise account of the results. The authors summarise our understanding of the area and provide the basis for understanding the more complex state of the heliosphere around solar maximum. The first chapter provides an overview of the region, introducing the heliosphere prior to the Ulysses mission, and mission objectives. Subsequent chapters discuss the areas of the heliosphere, large and small scale features, cosmic rays and energetic particles, and the observations of interstellar gas and cosmic dust.

The Sun to the Earth -- and Beyond by National Research Council,Division on Engineering and Physical Sciences,Space Studies Board,Solar and Space Physics Survey Committee Pdf

The sun is the source of energy for life on earth and is the strongest modulator of the human physical environment. In fact, the Sun's influence extends throughout the solar system, both through photons, which provide heat, light, and ionization, and through the continuous outflow of a magnetized, supersonic ionized gas known as the solar wind. While the accomplishments of the past decade have answered important questions about the physics of the Sun, the interplanetary medium, and the space environments of Earth and other solar system bodies, they have also highlighted other questions, some of which are long-standing and fundamental. The Sun to the Earthâ€"and Beyond organizes these questions in terms of five challenges that are expected to be the focus of scientific investigations in solar and space physics during the coming decade and beyond.

Heliophysics: Evolving Solar Activity and the Climates of Space and Earth by Carolus J. Schrijver,George L. Siscoe Pdf

Heliophysics is a fast-developing scientific discipline that integrates studies of the Sun's variability, the surrounding heliosphere, and the environment and climate of planets. Over the past few centuries, our understanding of how the Sun drives space weather and climate on the Earth and other planets has advanced at an ever increasing rate. This 2010 volume, the last in this series of three heliophysics texts, focuses on long-term variability from the Sun's decade-long sunspot cycle and considers the evolution of the planetary system over ten billion years from a climatological perspective. Topics covered range from the dynamo action of stars and planets to processes in the Earth's troposphere, ionosphere, and magnetosphere and their effects on planetary climate and habitability. Supplemented by online teaching materials, it can be used as a textbook for courses or as a foundational reference for researchers in fields from astrophysics and plasma physics to planetary and climate science.

The 3-D Heliosphere at Solar Maximum by R.G. Marsden Pdf

The global structure of the heliosphere changes dramatically with the solar circle. Our knowledge of the heliosphere in three dimensions under solar-minimum conditions has advanced significantly in the last 10 years, largely as a result of the on-going ESA/NASA Ulysses mission. Similar advances in our understanding of the heliosphere at solar maximum are to be expected with the return of Ulysses to the Sun's polar regions in 2000/2001. The papers in this volume address a wide range of topics related to the solar-maximum heliosphere, and include many of the latest findings from Ulysses and other space-based missions. Ground-based studies and theoretical modeling are also well represented. Specific questions include: what are the dominant processes that determine the global structure of the inner heliosphere under conditions of high solar activity, and what are the key differences between the high-latitude heliosphere at solar maximum and solar minimum? The book is intended for those carrying out active research in the fields of solar and heliospheric physics.

Observatories in Earth Orbit and Beyond by Y. Kondo Pdf

When I became President of International Astronomical Union Commission 44 for the triennial period 1985-1988, several members of the Organizing Committee and I agreed that it would be a good idea for our Commission to host a conference on observatories in space in view of their increasingly important role in astronomi cal research. IAU Colloquium Number 123 "Observatories in Earth Orbit and Beyond" is the first colloquium sponsored by IAU Com mission 44 on Astronomy from Space, although Commission 44 has co-sponsored numerous colloquia and symposia in the past. The past two decades have seen a flourishing of astronomical observatories in space. Over a dozen orbiting observatories have opened up a new window on the universe, providing hitherto una vailable data in the electromagnetic spectral range from gamma-ray, X-ray, ultraviolet to infrared and radio. This has clearly demon strated the crucial nature of astronomical observations from space. The invited talks of present colloquium consist primarily of reviews of currently operating observatories in space, future observatories that have been approved by sponsoring government or space agencies, the launch systems of U.S.A., E.S.A., U.S.S.R. and Japan, discussions of various orbits and sites (such as the Moon), and alternate approaches in designing space observatories. Several panel discus sions addressed those issues as well as the major unsolved problems of astronomy. Contributed poster papers included descriptions of space observatories that are in planning stage.

The Solar System Beyond Neptune by M. Antonietta Barucci Pdf

A new frontier in our solar system opened with the discovery of the Kuiper Belt and the extensive population of icy bodies orbiting beyond Neptune. Today the study of all of these bodies, collectively referred to as trans-Neptunian objects, reveals them to be frozen time capsules from the earliest epochs of solar system formation. This new volume in the Space Science Series, with one hundred contributing authors, offers the most detailed and up-to-date picture of our solar systemÕs farthest frontier. Our understanding of trans-Neptunian objects is rapidly evolving and currently constitutes one of the most active research fields in planetary sciences. The Solar System Beyond Neptune brings the reader to the forefront of our current understanding and points the way to further advancement in the field, making it an indispensable resource for researchers and students in planetary science.

The Outer Heliosphere: The Next Frontiers by E. Marsch,H.-J. Fahr,K. Scherer Pdf

The eleventh COSPAR colloquium The Outer Heliosphere: The Next Frontiers was held in Potsdam, Germany, from 24-28 July, 2000, and is the second dedicated to this subject after the first one held in Warsaw, Poland in 1989. Roughly a century has passed after the first ideas by Oliver Lodge, George Francis Fitzgerald and Kristan Birkeland about particle clouds emanating from the Sun and interacting with the Earth environment. Only a few decades after the formulation of the concepts of a continuous solar corpuscular radiation by Ludwig Bierman and a solar wind by Eugene Parker, heliospheric physics has evolved into an important branch of astrophysical research. Numerous spacecraft missions have increased the knowledge about the heliosphere tremendously. Now, at the beginning of a new millenium it seems possible, by newly developed propulasion technologies to send a spacecraft beyond the boundaries of the heliosphere. Such an Interstellar Proce will start the in-situ exploration of interstellar space and, thus, can be considered as the first true astrophysical spacecraft. The year 2000 appeared to be a highly welcome occassion to review the achievements since the last COSPAR Colloquia 11 years ago, to summarize the present developments and to give new impulse for future activities in heliospheric research.
