Spectrophysics
Spectrophysics covers those applications of spectroscopy that are directed at investigating the interactions or radiating atoms and molecules with their environment, with particular reference to the fields of astrophysics, plasma physics and atmospheric physics. Much of the material is normally found only in specialized texts.
Precision Spectroscopy in Astrophysics
High-accuracy Doppler shift measurements and high-precision spectroscopy are primary techniques in the search for exo-planets. Further extremely interesting applications include the analysis of QSO absorption lines to determine the variability of physical constants and the analysis of the isotopic ratios of absorption lines both in stars and in QSOs, and the determination of stellar oscillations through radial velocity measurements. Since the use of high-precision/resolution spectroscopy is closely connected to the ability to collect a large number of photons, the scientific domains using this technique benefit tremendously from the use of 8-meter class telescopes and will fully exploit the tremendous gain provided by future Extremely Large Telescopes (ELTs). IR high-resolution spectroscopy should soon approach the same accuracy regime achieved in the optical range. This volume comprehensively covers the astrophysical and technical aspects of high-precision spectroscopy with an outlook to future developments, and represents a useful reference work for researchers in those fields.
Astrophysical Lasers
Progress in modern radio astronomy led to the discovery of space masers in the microwave range, and it became a powerful tool for studies of interstellar star-forming molecular clouds. Progress in observational astronomy, particularly with ground-based huge telescopes and the space-based Hubble Space Telescope, has led to recent discoveries of space lasers in the optical range. These operate in gas condensations in the vicinity of the mysterious star Eta Carinae (one of the most luminous and massive stars of our Galaxy). Both maser and laser effects, first demonstrated under laboratory conditions, have now been discovered to occur under natural conditions in space too. This book describes consistently the elements of laser science, astrophysical plasmas, modern astronomical observation techniques, and the fundamentals and properties of astrophysical lasers. A book with such an interdisciplinary scope has not been available to date. The book will also be useful for a wider audience interested in modern developments of the natural sciences and technology.
Eta Carinae and Other Mysterious Stars
Annotation Observational data, laboratory measurements, and modeling efforts are reported in these papers from a conference on the massive star Eta Carinae and other stars with peculiar spectroscopic signatures. Organized in sections on the spectroscopy of Eta Carinae from X-rays to radio, questions from spectroscopy of other peculiar emission line stars, fluorescence and radiative processes, and spectra of Eta Carinae and Weigelt blobs BD, the papers deal with aspects of the field such as Raman scattering and symbiotic stars, the origin of strings in the outer regions in Eta Carinae, selective emission lines in O-type spectra, and cool star chromospheres and the sun.

Proceedings of the Twenty Sixth General Assembly Prague 2006
IAU Transactions XXVIB contains the Proceedings of the IAU XXVII General Assembly held in Prague, 14-25 August 2006, hosting a total of 2412 participants from 73 countries. The Assembly featured a rich scientific program, comprising 6 Symposia, 17 Joint Discussions and 7 Special Sessions. During the program about 650 papers were presented and more than 1550 posters displayed. The Proceedings of the 6 Symposia have been published in the Proceedings of the IAU Symposia Series, and the proceedings of the Joint Discussions and Special Sessions feature in IAU Highlights of Astronomy, 14. Together with those 7 volumes, these Transactions cover the entire General Assembly. In addition to the scientific program, the XXVI General Assembly hosted the regular Business Meetings of the EC, the 12 Divisions, 40 Commissions and 75 Working Groups. This volume records the organizational and administrative business of the XXVI General Assembly and the status of the IAU membership.
High Time Resolution Astrophysics
This is quite simply the first volume of its kind dedicated to the area of high time resolution astrophysics. High time resolution astrophysics (HTRA) is an important new window on the universe and a vital tool in understanding a range of phenomena from diverse objects and radiative processes. Underlining this science foundation, technological developments in both instrumentation and detectors are described.
High Resolution Infrared Spectroscopy in Astronomy
Two specialized new instruments for ESO's VLT, VISIR and CRIRES, spawned the idea for this workshop. CRIRES is a dedicated very high resolution infrared spectrograph; VISIR features a high resolution spectroscopic mode. Together, the instruments combine the sensitivity of an 8m-telescope with the now well-established reliability of VLT-facility instruments. High resolution here means that lines in cool stellar atmospheres and HII-regions can be resolved. The astrophysical topics discussed in this rather specialized workshop range from the inner solar system to active galactic nuclei. There are many possibilities for new discoveries with these instruments, but the unique capability, which bec...
Women At Imperial College; Past, Present And Future
This book is a celebration of women in science, technology, medicine and business at Imperial College London. It shows the inspirational role women played in the creation of the legacy of the College since its inception, and represents a guide to their achievements. Biographies and archive material provide an insight into their academic work and social lives, while first-hand information collected for individual cases gives a comprehensive overview of student and professional life in their diverse fields and subjects. Further careers as academics and businesswomen are also documented, demonstrating the importance of and wider social impact of women in the sciences.
