Book Description
Solar flares are very complex electromagnetic phenomena of a cataclysmic nature. Particles are accelerated to very high velocities and a variety of physical processes happen inside and outside flares. These processes can be studied by a large number of techniques from Earth and from space. The aim is to discover the physics behind solar flares. This goal is complicated because information about the flare mechanism can be obtained only in an indirect way by studying the secondary effects. This book provides three stages in the solution of the solar flare problem. Chapter one describes the connection between observational data and theoretical concepts, where it is stressed that next to investigating flares, the related non-stationary large-scale phenomena must be studied as well. The second chapter deals with secondary physical processes, in particular the study of high-temperature plasma dynamics during impulsive heating. The last chapter presents a model built on the knowledge of the two previous chapters and it constructs a theory of non-neutral turbulent current sheets. The author believes that this model will help to solve the problem of solar flares. For solar physicists, plasma physicists, high-energy particle physicists.

Book Description
There is a force out there that could destroy our world in minutes. . . . Solar flares—brief bursts of radiation from our sun—have always existed and have never been particularly dangerous. Nature hasn’t changed. But we have. By making our world so dependent on electricity delivered by huge, unprotected power grids we have inadvertently placed humanity at terrible risk. As bestselling author Whitley Strieber explores in this urgent new work, a powerful solar flare could demolish our electrical delivery system, wiping away centuries of civilization in minutes and drastically changing our world. Such a scenario is altogether plausible—and it is the single most dangerous single thing that could happen to our civilization, more dangerous than the most massive earthquake or volcano, more dangerous than climate change, more dangerous even than nuclear war. What is worse, solar flares of a now-dangerous intensity are not all that uncommon; and not only that, our electrical and electronic infrastructure is becoming so extensive, and thus so fragile, that smaller and smaller solar flares can pose more and more serious hazards. Due to the astonishing unwillingness of power companies to cooperate, good programs that would make us safer, and that are supported by both political parties, have been routinely prevented from being enacted. In Solar Flares: What You Need to Know, Strieber reveals the dangers behind solar flares, tracks the disastrous damage they could cause, surveys what they would do to our world in the here-and-now, and explains what nations and individuals must do to prepare for them.

Book Description
Sudden Ionospheric Disturbances resulting from an interaction of the Solar Flare radiation with the constituents of the upper atmosphere constitute one of the three major aspects of ground level monitoring of solar flares -the other two being optical observations of flares, and the observations of solar bursts in radio wavelengths. SIDs, therefore, form a major part of flare monitoring programme in many observatories. Unlike the other two, however, the ionospheric effects of flares provide one major additional source of interest - the reaction of the ionospheric plasma to an impulsive ionization. The high atmosphere provides a low pressure laboratory without walls in which a host of reactions occur between electrons, ions and neutral particles. The resulting products and their distributions may bear no resemblance to those of the primary neutral constituents or their direct ionization products. The variations with the time of the day, with season and with solar activity that form the bulk of the ionospheric measurements are too slow to allow any insight into the nature of these ionospheric reactions whose lifetimes are often very short. The relaxation time of the ionospheric ionization is only a few minutes or fraction of a minute in the lower ionosphere and in the E-region and is about 30 min to an hour at 300 km. The flares provide a sudden short impulse comparable to these time scales.

Book Description
"The world has been plunged into darkness and society as we know it has launched into chaos. Jake Clifford was just a regular guy - a man trying to achieve greatness in his career and a father doing his best to be the man his daughter deserved. That is, until a solar flare makes contact with Earth, wiping out all electricity and modern technology with one fatal blow. Now, Jake must adapt to this new world hoping to one day be reunited with his daughter who was states away when the lights went out." --

Book Description
This book provides results of analysis of typical solar events, statistical analysis, the diagnostics of energetic electrons and magnetic field, as well as the global behavior of solar flaring loops such as their contraction and expansion. It pays particular attention to analyzing solar flare loops with microwave, hard X-ray, optical and EUV emissions, as well as the theories of their radiation, and electron acceleration/transport. The results concerning influence of the pitch-angle anisotropy of non-thermal electrons on their microwave and hard X-ray emissions, new spectral behaviors in X-ray and microwave bands, and results related to the contraction of flaring loops, are widely discussed in the literature of solar physics. The book is useful for graduate students and researchers in solar and space physics.

Book Description
The Sun as a Guide to Stellar Physics illustrates the significance of the Sun in understanding stars through anexamination of the discoveries and insights gained from solar physics research. Ranging from theories to modelingand from numerical simulations to instrumentation and data processing, the book provides an overview of whatwe currently understand and how the Sun can be a model for gaining further knowledge about stellar physics.Providing both updates on recent developments in solar physics and applications to stellar physics, this bookstrengthens the solar–stellar connection and summarizes what we know about the Sun for the stellar, space, andgeophysics communities. - Applies observations, theoretical understanding, modeling capabilities and physical processes first revealed by the sun to the study of stellar physics - Illustrates how studies of Proxima Solaris have led to progress in space science, stellar physics and related fields - Uses characteristics of solar phenomena as a guide for understanding the physics of stars

Book Description
It seemed like just another normal day for the story's main character, Jake Clifford. Little did he, or any one else, know that an x-class Solar Flare was heading straight for Earth. This looks like it will be the last "normal" day Jake and his friends will have in a long, long time.
