Book excerpt: Observational data are given on the infrared irradiance from stars. These data and certain criteria, postulated herein, enable a prediction of the number of stars that yield spectral irradiances (to 22 microns) which equal or exceed indicated levels. Establishment of credible growth rates of the number of stars with stellar magnitude, in the infrared, constitutes the critical element of the prediction technique. The prediction is speculative. It should be closer to reality, however, than current predictions based on spectral extrapolation from the visual components of the radiation of stars. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Optics is reborn. There is fresh new vitality in applying old techniques to new prob lems and fully exploring novel phenomena. Lasers, holography, stellar navigation, nonlinear phenomena, and remote sensing are subjects of the seventies, and their further development will increase our understanding of nature and the development of technology. This Series is devoted to provid ing ideas and data to nourish the growth of these scientific and engineering en deavors' for we feel strongly that science and engineering flourish best when they grow together. Some of the volumes in the Series will be devoted to the optical properties of materials, theories of the detailed mechanisms of absorption, reflection, and nonlinea r phenomena, and electro-optical coefficients. The understanding of such things leads to further engineering applications. Companions to such theoretical books will be compendia of property data; the triad is completed by monographs on the use of the materials in op tical and electro-optical systems. Laser materials, lasers, and laser sys tems form one of the groups which will comprise the full set of ready-reference material for the entire field. The Series will be intentionally international, including a fair sampling of Russian work. There are important benefits to be obtained in the alternate approaches often taken by our Soviet and other foreign colleagues (just as they can gain from studying ours).

Available in PDF, EPUB and Kindle. Book excerpt: A sweeping tour of the infrared universe as seen through the eyes of NASA’s Spitzer Space Telescope Astronomers have been studying the heavens for thousands of years, but until recently much of the cosmos has been invisible to the human eye. Launched in 2003, the Spitzer Space Telescope has brought the infrared universe into focus as never before. Michael Werner and Peter Eisenhardt are among the scientists who worked for decades to bring this historic mission to life. Here is their inside story of how Spitzer continues to carry out cutting-edge infrared astronomy to help answer fundamental questions that have intrigued humankind since time immemorial: Where did we come from? How did the universe evolve? Are we alone? In this panoramic book, Werner and Eisenhardt take readers on a breathtaking guided tour of the cosmos in the infrared, beginning in our solar system and venturing ever outward toward the distant origins of the expanding universe. They explain how astronomers use the infrared to observe celestial bodies that are too cold or too far away for their light to be seen by the eye, to conduct deep surveys of galaxies as they appeared at the dawn of time, and to peer through dense cosmic clouds that obscure major events in the life cycles of planets, stars, and galaxies. Featuring many of Spitzer’s spectacular images, More Things in the Heavens provides a thrilling look at how infrared astronomy is aiding the search for exoplanets and extraterrestrial life, and transforming our understanding of the history and evolution of our universe.

Download or read book Infrared Astronomy written by G. Setti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a series of lectures presented at the 4th Course of the International School of Astrophysics, held in Erice (Sicily) from July 9 - July 20, 1977 at the "E. Majorana" Centre for Scientific Culture. The course was fully supported by a grant from the NATO Advanced Study Institute Programme. It was attended by 82 participants from 15 countries. Even though the infrared portion of the electromagnetic spectrum covers an extensive interval from the red region of the optical spectrum (10,000 A) to the microwave radio region (1 mm), its role in astronomy has been minimal until the last two decades. Until very recently, the only objects observed were the sun, the moon and the planets. A primary reason for this late development was the lack of sensitive detectors and the necessary cryogenic technology that must accompany their use. Recent progress in this technology has been paralleled by an ever increasing interest of astronomers in infrared observations, leading to a number of ex tremely important results in different branches of astronomy. This becomes evident when one realizes that in many astrophysical conditions most of the energy is found to be channeled into the infrared portion of the electromagnetic spectrum. Stars were detected that yield most of their radiation in the infrared; these objects present a new view of stellar evolution, both in the birth and death stages.
Download or read book Spectral Irradiance Calibration in the Infrared XVI Improved Accuracy in the Infrared Spectra of the Secondary and Tertiary Standard Calibration Stars written by and published by . This book was released on 2006 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have increased the spectral resolution and accuracy of the absolute infrared spectral flux for a subset of stellar standards created by Cohen and his collaborators in previous papers in this series. We combined the moderate-resolution spectroscopy obtained on infrared standard stars by the Short Wavelength Spectrometer on the Infrared Space Observatory with high-quality photometry that is tied to our recent absolute calibration from the Midcourse Space Experiment. New spectra were created for 33 stars, 9 of which are Cohen et al. secondary standards and another 20 of which are tertiary standards for which Cohen adopted spectral templates. The effective temperatures and angular diameters for the stars are derived from the absolute spectra and compare favorably with independent measures of these quantities in the literature. The present spectra display systematic differences with those of Cohen and colleagues in that they have 4%-7% lower fluxes in the 1-4 micrometer spectral region. Our spectra remove the A-K star calibration bias recently noted in the calibration of the Spitzer Space Telescope camera.

Download or read book Near Infrared Photometry of Late Type Stars written by Russell G. Walker and published by . This book was released on 1968 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A multi-band photoelectric photometer for making observations in the U, B, V, and infrared bands W(1.06 microns) X(1.13 microns), Y(1.63 microns) and Z(2.21 microns) was constructed and applied to both stellar and planetary observations. The results of photometry obtained for 61 stars are presented. The observations at lambda = 1.63 microns are shown to exhibit an excess flux due to a minimum in the H opacity in accordance with the predictions of model atmosphere studies. Bolometric corrections are derived for stars of late spectral type from integration of the observed absolute spectral irradiance curve. A simple photometric method for measuring stellar diameters is proposed based upon the absolute irradiance observed at 2.21 microns and the 2.21 microns flux at the surface of the star calculated from model atmospheres. Angular diameters derived by this technique are consistent with interferometric results and, when combined with the bolometric corrections, effective temperatures are found. (Author).

Download or read book Infrared Astronomy Seeing the Heat written by David L. Clements and published by CRC Press. This book was released on 2014-11-21 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncover the Secrets of the Universe Hidden at Wavelengths beyond Our Optical Gaze William Herschel’s discovery of infrared light in 1800 led to the development of astronomy at wavelengths other than the optical. Infrared Astronomy – Seeing the Heat: from William Herschel to the Herschel Space Observatory explores the work in astronomy that relies on observations in the infrared. Author David L. Clements, a distinguished academic and science fiction writer, delves into how the universe works, from the planets in our own Solar System to the universe as a whole. The book first presents the major telescopes in the world of observational infrared astronomy, explains how infrared light is detected through various kinds of telescopes, and describes practical problems that send infrared astronomers to the tops of mountains and their telescopes into orbit and beyond. Much of the book focuses on what infrared astronomers find in their observations. You’ll discover what infrared astronomy reveals about the planets, moons, and other bodies that constitute our Solar System; star formation and stellar evolution; the processes that shape galaxies; and dark energy and dark matter. Infrared astronomy has revolutionized our understanding of the universe and has become essential in studying cosmology. Accessible to amateur astronomers, this book presents an overview of the science and technology associated with infrared astronomy. With color figures, it shows you how infrared astronomy provides insights into the workings of the universe that are unavailable at other wavelengths.
