Book Description
'Computational History' derives history from data and nowadays, therefore, relies on the technologies of the digital humanities. 'Computational History of Science' addresses questions of history by evaluating historical data, e.g. for tracing back copying traditions and conclude on transfer and transformation of data and knowledge. The term 'Applied Historical Astronomy', in contrast, tries to address questions of contemporary science by evaluating historical data in comparison with most recent data. This opens new possibilities, e.g. in the search for stellar transients among historical data. In the contribution by Hoffmann & Vogt we will focus on the stellar transients among all the topics mentioned above. Philipp Protte discusses the accuracy of magnitudes and positions in ancient star catalogues, Andreas Schrimpf & Frank Verbunt present an analysis of an early modern star catalogue. Victor Reijs analyses the visibility of celestial objects for naked-eye observers, and Björn Kunzmann showcases some important variable stars in the history of astronomy. Rene Hudec presents astronomical photographic archives as a valuable data source for modern astrophysics. José M. Vaquero discusses the studies on solar observations made during the last four centuries. More technical are the contributions of Georg Zotti on Stellarium and Karsten Markus-Schnabel on data-mining and data-processing technologies. Ido Yavetz & Luca Beisel are developing a digital tool of computational history of science for the simulation of pre-modern astronomical models. Gerd Graßhoff focuses more on the application of computational history with regard to Kepler's Astronomia Nova while Tim Karberg presents an analysis of the astronomical orientation of buildings in the North Sudan.

Book Description
Cool evolved stars are among the brightest point sources in the infrared sky, and contribute significantly to the interstellar dust of galaxies. They are in a short-lived but important stage of stellar evolution, characterized by pulsations, dust formation, and the production of expanding circumstellar shells. This conference highlighted the physics of evolved cool stars in relation to their stage of evolution, atmospheric structure and dynamics, stellar winds, and associated dust formation. The conference was held at the Millennium Centre near the campus of East Tennessee State University in Johnson City, Tennessee, in July 2007. It brought together astronomers, both professional and amateur, who are working on different aspects of cool star research. These included dust theorists, numerical modelers, and experts in observations at different wavelengths. The result of the meeting was a more complete picture of these stars, which is summarized in this volume. Several recent developments motivated the need for this conference. Current hydrodynamic models of evolved stars are now able to reproduce the optical/UV spectra of such stars. However, simultaneous modeling of the infrared spectrum has proven difficult. Also, adding dust to such modeling is problematic because of the complicated physics of dust formation, destruction, and emission in these dynamic environments. Furthermore, the exact evolutionary relationship between the various types of cool evolved stars still is uncertain. The perceptive reader will discover a number of provocative research directions embedded in the many fine contributions herein.

Book Description
A portrait of trailblazing astronomer Henrietta Leavitt and an illustrated exploration of the power of attention in scientific observation, artistic creation, and the making of meaning. Our galaxy, the Milky Way, has a diameter of about 100,000 light years—a figure we can calculate because of the work of Henrietta Leavitt (1868–1921), who spent decades studying glass plate photographs of the night sky. Visual artist and researcher Anna Von Mertens’s Attention Is Discovery is a fascinating portrait of this remarkable woman who laid the foundation for modern cosmology, as well as an exploration of the power of looking and its revelatory role at the center of scientific discovery. Ushering us into the scientific community of women who worked alongside Leavitt, now known as the Harvard Computers, Von Mertens describes the inventive methodologies Leavitt devised to negotiate the era’s emerging photographic technology. Interspersed with Von Mertens’s meticulously researched and lyrically written essays are collaborations with art historian Jennifer L. Roberts, cosmologist Wendy Freedman, astrophysicist João Alves, and novelist Rebecca Dinerstein Knight. Alongside Leavitt’s process, evident in her astronomical logbooks and ink notations on the glass plates, Von Mertens includes details of the hand-stitched quilts and graphite drawings she made in response to Leavitt’s legacy. Photographs made by Jennifer L. Roberts using a macro lens amplify the material richness of these artworks and archives. This interweaving of text and image engages and rewards the reader’s own close attention. Highlighting ways that subtle, repeated actions build meaning—whether skilled, technical observation, the crafting of an object, or the mundane tasks that construct our exquisite lives—Von Mertens’s pairing of close looking with close reading creates a layered portrait of Henrietta Leavitt that acknowledges the significance of her discovery and the richness of its inheritance.

Book Description
Explore the eighteenth-century Indian astronomical observatories called the Jantar Mantars, massive, stunning structures built to observe and understand the heavens Between 1724 and 1730, Maharaja Sawai Jai Singh II of Jaipur constructed five astronomical observatories, called Jantar Mantars, in northern India. The four remaining observatories are an extraordinary fusion of architecture and science, combining elements of astronomy, astrology, and geometry into forms of remarkable beauty. The observatories’ large scale and striking geometric forms have captivated the attention of architects, artists, scientists, and historians worldwide, yet their purpose and use remain largely unknown to the public. In this book, Barry Perlus’s visually driven exploration brings readers to the Jantar Mantars and creates an immersive experience. Panoramas plunge the viewer into a breathtaking 360-degree space, while pages of explanatory illustrations describe the observatories and the workings of their many instruments. The book provides the experience of visiting the sites, the historical context of the Jantar Mantars, and an understanding of their scientific and architectural innovations.

Book Description
Au verso de la couverture : "The international Hinode mission was launched from Japan on 23 September 2006. The spacecraft carries a suite of instruments that permit observations of the Sun and its atmosphere with unprecedented resolution and precision. During its first two years of operation, Hinode has enabled numerous breakthroughs in our understanding of magnetic fields within the solar atmosphere and their relationship to the energetic solar phenomena that affect the Earth's space environment. Some of those breakthroughs were presented at the First Hinode Science Meeting held in Dublin, Ireland, in August 2007 (ASPCS Volume 397). By the time the Second Hinode Science Meeting was held in Boulder, Colorado, 29 September-3 October 2008, researchers had been able to subject Hinode data to in-depth, quantitative analyses and to make comparisons with detailed numerical and analytic models of solar phenomena. This volume presents brief summaries of work presented at the Second Hinode Science Meeting"

Book Description
Recording the proceedings of the IAU XXVI General Assembly, this volume of the IAU Highlights of Astronomy covers virtually all aspects of modern astrophysics as discussed by 2400 participants from 73 countries. Notably, the common aspects of astrophysical phenomena known to exist in widely differing interstellar environments is thoroughly examined, providing fertile cross correlation from one specialisation to another. This text highlights the importance of the triennial IAU General Assemblies in bringing together the work of observers and theoreticians in widely different fields, but working towards a common goal: understanding the physics of the Universe. Together with the Proceedings of the IAU Symposia 235-240, this volume examines all of the astrophysics presented at the General Assembly.
