Available in PDF, EPUB and Kindle. Book excerpt: The role of the negative hydrogen ion, in the energy balance of the deep chromosphere is reassessed and quantitatively evaluated. We find that in quiet Sun conditions the negative hydrogen ion (H) is a heating agent, absorbing more photospheric radiation than it reradiates. We further propose that during flares a flux of UV radiation produces over ionization of the deep chromosphere (principally by ionizing neutral silicon) and that the increased electron density so produced causes an increase in the H + e yields H association rate and so an increased H abundance. The resulting increased absorption of photospheric radiation by the H ions produces heating compatible with observations. (Author).

Download or read book Flare Observations in the IRIS Era: What Have We Learned, and What’s Next? written by Vanessa Polito and published by Frontiers Media SA. This book was released on 2023-12-27 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its launch in 2013, IRIS has observed more than 10 X-class, over 100 M-class and more than 600 C-class flares at unprecedented spatial and temporal resolution. Thanks to the rich diagnostics that cover the physical conditions of the solar atmosphere from the photosphere to the hottest parts of the flaring corona, IRIS observations have provided exciting new results and constraints on flare heating models, significantly expanding our knowledge of how flares are triggered, and how the non-thermal energy is released, propagates downward from the corona, and is deposited in the low atmosphere. At the same time, the new discoveries provided by IRIS have raised new unresolved questions and new challenges for theoretical models. For instance, current hydrodynamic models still cannot fully explain many features observed by IRIS during both the impulsive and gradual phases such as the dynamics of the evaporative/condensation flows, the large line broadenings, and the puzzling complex and broad chromospheric lines. In addition, important questions remain regarding the details of the energy propagation and dissipation in flares, the importance of Alfvén waves vs electron-beam and thermal conduction heating, and the effects from large-scale reconfiguration of the magnetic field during flares.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The COSPAR Colloquium on Solar-Terrestrial Magnetic Activity and Space Environment (STMASE) was held in the National Astronomy Observatories of Chinese Academy of Sciences (NAOC) in Beijing, China in September 10-12, 2001. The meeting was focused on five areas of the solar-terrestrial magnetic activity and space environment studies, including study on solar surface magnetism; solar magnetic activity, dynamical response of the heliosphere; space weather prediction; and space environment exploration and monitoring. A hot topic of space research, CMEs, which are widely believed to be the most important phenomenon of the space environment, is discussed in many papers. Other papers show results of observational and theoretical studies toward better understanding of the complicated image of the magnetic coupling between the Sun and the Earth, although little is still known little its physical background. Space weather prediction, which is very important for a modern society expanding into out-space, is another hot topic of space research. However, a long way is still to go to predict exactly when and where a disaster will happen in the space. In that sense, there is much to do for space environment exploration and monitoring. The manuscripts submitted to this Monograph are divided into the following parts: (1) solar surface magnetism, (2) solar magnetic activity, (3) dynamical response of the heliosphere, (4) space environment exploration and monitoring; and (5) space weather prediction. Papers presented in this meeting but not submitted to this Monograph are listed by title as unpublished papers at the end of this book.
