Book Description
This timely volume provides the first comprehensive review and synthesis of current understanding of magnetic fields in the Sun and similar stars. Magnetic activity results in a wealth of phenomena - including starspots, non-radiatively heated outer atmospheres, activity cycles, deceleration of rotation rates, and even, in close binaries, stellar cannibalism - all of which are covered clearly and authoritatively. This book brings together for the first time recent results in solar studies and stellar studies. The result is an illuminating new view of stellar magnetic activity. Key topics include radiative transfer, convective simulations, dynamo theory, outer-atmospheric heating, stellar winds and angular momentum loss. Researchers are provided with a state-of-the-art review of this exciting field, and the pedagogical style and introductory material make the book an ideal and welcome introduction for graduate students.

Book Description
This volume is a collection of research articles on the subject of solar flares and flares on other cool stars, which are currently extensively studied using new ground- and space-based instruments, together with highly sophisticated numerical simulations. The collection memorializes the work of a pioneer in the study of solar physics, Professor Zdenek Švestka (1925 Prague – 2013 Bunschoten), a leading expert in the field of solar flares and the co-founder and Editor-in-Chief of the journal Solar Physics. The book contains many contributions to the conference “Solar and Stellar Flares: Observations, simulations and synergies”, held in Prague during 23 – 27 June 2014, organised in honor and memory of Professor Švestka. Originally published as Topical Issue of Solar Physics, Vol. 290, Issue 12, 2015.

Book Description
concert at Dinkelspiel Auditorium 'An Evening of Songs and Arias' hosted by Dr Kip Cranna of San Francisco Opera, produced and directed by Elizabeth Tucker, and featuring soprano Ellie Holt Murray, mezzo-soprano Marsha Sims; tenor Richard Walker, and baritone David Taft Kekuewa, with piano accompaniment by Mark Haffner, staff coach for San Francisco Opera. Two scientific themes clearly emerged from this conference: (1) the key to progress in flare research lies in a multispectral approach with as much temporal resolution as the photon fluxes allow; and (2) the key to understanding the physics lies in a dynamic interaction between solar and stellar investigations and investigators. During the eight sessions solar and stellar topics were balanced and intermixed in 33 invited and oral presentations. We are particularly pleased that these proceedings will be the springboard to publication of solar-stellar articles in the journal Solar Physics. In addition, 115 very exciting posters were also displayed and a companion volume containing many of these is available as a publication of the Catania Astrophysical Observatory. We dedicate this book to the Solar Maximum Mission and to the Flare Star Consor tium. To all our solar-stellar friends and colleagues: 'Thank you!' BERNHARD M.

Book Description
The Sun as a Guide to Stellar Physics illustrates the significance of the Sun in understanding stars through an examination of the discoveries and insights gained from solar physics research. Ranging from theories to modeling and from numerical simulations to instrumentation and data processing, the book provides an overview of what we 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 book strengthens the solar–stellar connection and summarizes what we know about the Sun for the stellar, space, and geophysics 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
Recent advances in observations and modelling of solar and stellar flares have opened up new perspectives for understanding the fundamental physical mechanisms of magnetic energy storage and release, particle acceleration, and their radiative and dynamical processes. New interest in this topic is stimulated by Kepler observations and the discovery of superflares on solar-type stars, which raises questions about the possibility of such flares on the Sun, and the potential effects of superflares on terrestrial and extraterrestrial planets, including their impact on the origin and evolution of life. IAU Symposium 320 discusses the recent advances in observations and theories of solar and stellar flares, focusing on the understanding of their phenomenological and physical aspects, as well as consequences for terrestrial planets and exoplanets. This volume will be useful to researchers of all levels working in this fascinating and rapidly developing field of astronomy.

Book Description
Kepler observations revealed that many sun-like stars produce flares that are much greater strength in terms of total luminosity visual wavelengths compared to solar flares. It is well known that energy released in solar flares is stored in the magnetic field structures which are anchored to sun through sunspots. Powerful flares that are produced at locations of greater energy storage that often manifest in more light output. As such, relation between the sunspot area and flare productivity have been observed since long. Since the flares occur at the locations of flux emergence, it is possible to relate the fluctuation in spot area with flare productivity. Assuming that the stellar flares occur due to similar processes as solar flares, we have investigated superflares data that are taken from the Kepler catalog in order to find relationship between the flare frequencies with spot activity. We measured the flare frequencies by counting the number of flares produced by the star during an observing quarter. The amplitude of the light curve is estimated by computing the contrast, which is due to the passage of star spot on stellar disk. Larger mean contrast would be produced by bigger star-spots, which is a measure of surface magnetic field. The standard deviation of mean contrast is used as a measure of fluctuating field resulting from flux emergence. We examine the relationship between the amplitude of the light curve and its change with the flare frequency. Our results show that the flare frequency of a star increase with the contrast of the light curve observed with Kepler instrument. This shows that the large stellar flares are produced at the locations of greater magnetic field reserve. Dependence of flux emergence in flare frequency is less obvious. In the second part of our research, we investigated Kepler IDs pre- flare dips. We observed ten stellar flares with pre- flare dip on Kepler device. We found that the flare amplitude increase with the pre- flare dip flux, however, this is not a reliable result as relativity we do not have enough data.
