Download or read book Infrared Observations of the Outer Solar Corona written by Robert M. MacQueen and published by . This book was released on 1968 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2.2 microns wavelength outer solar corona has been observed in two experiments: first, employing a ground-based telescope during the 93 second totality of the eclipse of 12 November 1966; and second, employing a balloon package with an infrared coronagraph, flown to an altitude of 28 km, during a 5.25 hour period, on 9 January 1967. The design and evaluation of the balloon-borne coronagraph is discussed, and the various origins of stray light investigated. The flight coronagraph was found to introduce a stray radiance of less than 3 x 10 to the -12th power B sub dot, where B sub dot is the radiance of the mean solar disk at 2.2 microns. During eclipse the corona was observed from 2 to 6 solar radii in the ecliptic plane, and at a single point perpendicular to the ecliptic, at 5 solar radii. Balloon observations covered the range 3.7 to 10 solar radii, at position angles from 20 degrees north to 40 degrees south of the ecliptic, on the east limb of the sun. Features attributed to the vaporization of interplanetary material were observed at 3.5, 4, 8.7 and 9.2 solar radii, the former two during the period of totality, and the latter three during the balloon observations.

Book excerpt: This volume presents the latest research results on solar prominences, including new developments on e.g. chirality, fine structure, magnetism, diagnostic tools and relevant solar plasma physics. In 1875 solar prominences, as seen out of the solar limb, were described by P.A. Secchi in his book Le Soleil as "gigantic pink or peach-flower coloured flames". The development of spectroscopy, coronagraphy and polarimetry brought tremendous observational advances in the twentieth century. The authors present and discuss exciting new challenges (resulting from observations made by space and ground-based telescopes in the 1990s and the first decade of the 21st century) concerning the diagnostics of prominences, their formation, their life time and their eruption along with their impact in the heliosphere (including the Earth). The book starts with a general introduction of the prominence “object” with some historical background on observations and instrumentation. In the next chapter, the various forms of prominences are described with a thorough attempt of classification. Their thermodynamic (and velocity) properties are then derived with emphasis on the methods (and their limits) used. This goes from the simplest optically thin case to the heavy radiative treatment of plasmas out of local thermodynamic equilibrium. The following chapters are devoted to the magnetic field measurements and indirect derivation. A new branch of diagnostic tools, the seismology, is presented along with some MHD basics. This allows to better understand the propagation of waves, the energy and force equilibria. Both small-scale and large-scale studies and their relationship are presented. The importance of the newly discovered cavities is stressed in the context of prominence destabilization. The issues of prominence formation and eruption, their connection with flares and Coronal Mass Ejections and their impact on the Earth are addressed on the basis of the latest results. Finally, an exciting new area of research is unveiled with the newly discovered evidence of similar manifestations in the Universe and their possible impact on the habitability of exoplanets. References to the basic physics (where necessary) are provided and the proposed web sites addresses will allow the reader to load exciting movies. The book is aimed at advanced students in astrophysics, post-graduates, solar physicists and more generally astrophysicists. Amateurs will enjoy the many new images which go with the text.

Book excerpt: Multi-wavelength observations from various solar missions have revealed the dynamic nature of the solar corona. The work presented in this thesis represents a contribution towards understanding some of the physical mechanisms that drive the activity observed in the corona and out into the heliosphere. In particular, the role of reconnection in active region (AR) outflows and AR-coronal hole (CH) interactions using observations of the associated plasma flow signatures and their relationship to the underlying magnetic field topology is examined. Persistent outflows discovered by Hinode EUV Imaging Spectrometer (EIS) occur at the boundary of all ARs over monopolar magnetic regions. It is demonstrated that the outflows originate from specific locations of the magnetic topology where field lines display strong gradients of magnetic connectivity, namely quasi-separatrix layers (QSLs). Magnetic reconnection at QSLs is shown to be a viable mechanism for driving AR outflows which are likely sources of the slow solar wind. Observational signatures and consequences of interchange reconnection (IR) are identified and analyzed in a number of solar configurations. Jet light curves of several emission lines show a post-jet enhancement in cooler coronal lines which has not been previously observed. In the case of emerging flux near a CH, it is shown that closed loops forming between the AR and CH leads to the retreat of the CH and a dimming of the corona in the vicinity of the like-polarity region. A filament eruption and coronal mass ejection (CME) from an AR inside a CH are observed from the solar disk into the heliosphere. An anemone structure of the erupting AR and the passage in-situ of an interplanetary CME (ICME) with open magnetic topology are interpreted to be a direct result of IR. Plasma flows resulting from the interaction between an AR embedded in a CH observed by Hinode EIS are investigated. Velocity profiles of hotter coronal lines reveal intensification in outflow velocities prior to a CME. The AR's plasma flows are compared with 3D magnetohydrodynamic (MHD) numerical simulations which show that expansion of AR loops drives outflows along the neighboring CH field. The intensification of outflows observed prior to the CME is likely to result from the expansion of a flux rope containing a filament further compressing the neighboring CH field.

Available in PDF, EPUB and Kindle. Book excerpt: The book presents a broad and in-depth overview of recent achievements and the current state of research in magnetohydrodynamic (MHD) oscillatory and wave phenomena in the coronae of the Sun and stars. Major progress in coronal wave studies has been achieved thanks to the combination of high-precision multi-wavelength observations with spaceborne and ground-based facilities, elaborated theory of the interaction of MHD waves with plasma non-uniformities, state-of-the-art numerical simulations, and novel data analysis techniques. It has allowed the research community to reach a new look at the role played by MHD wave processes in the enigmatic phenomena of coronal plasma heating and wind acceleration as well as powerful energy releases such as flares and coronal mass ejections. In addition, the waves are intensively used as natural probes in the remote diagnostics of the coronal plasma parameters and physical processes operating in solar and stellar coronae via the method of MHD seismology. Individual chapters cover recent cutting-edge results obtained on the analysis and theoretical modelling of several most intensively studied coronal MHD wave phenomena, namely, kink and sausage oscillations of coronal loops and other field-aligned plasma structures, plus running and standing slow magnetoacoustic waves. A dedicated chapter assesses the reliability of proposed theoretical mechanisms for heating of the coronal plasma by MHD waves. Another chapter summarizes the current state of our understanding of the physical mechanisms and observational properties of quasi-periodic pulsations in solar flares, considers their analogy with similar processes detected in stellar flares, and thus establishes solid ground for the further exploitation of the solar-stellar analogy. An important discussion of novel data analysis techniques designed recently for MHD seismology applications is presented in a devoted chapter. The direction of future advances in the designated research areas are discussed. The book is a spin-off from the Topical Collection "Oscillatory Processes in Solar and Stellar Coronae" of the journal Space Science Reviews.

This book was released on 2013-03-09 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar Physics publishes up to two Topical Issues per year that focus on areas of especially vigorous and active research. The present Topical Issue contains papers of recent results on the solar corona, as well as on the transition region and low solar wind. The majority of these papers, which were all refereed in accordance with the standards of Solar Physics, were presented in August 1999 at a workshop held in Monterey, California. The authors were offered the opportunity to present relevant parts of their contributions on an accompanying CD ROM of this Topical Issue. The Sun's magnetic field is responsible for the spectacularly dynamic and intri cate phenomenon that we call the corona. The past decade has seen an enormous increase in our understanding of this part of the solar outer atmosphere, both as a result of observations and because of rapid advances in numerical studies. The Yohkoh satellite has observed the Sun now for over eight years, producing spectac ular sequences of images that convey the complexity of the corona. The imaging and spectroscopic instruments on SOHO have added information on the cooler part of the corona. And since April of 1998 TRACE has given us very high resolution images of the 1-2 MK corona, at cadences that allow detailed observations of field oscillations, loop evolution, mass ejecta, etc.
