Content: " A concise and accessible introduction to exoplanets that explains the cutting-edge science behind recent discoveries For centuries, people have speculated about the possibility of planets orbiting distant stars, but only since the 1990s has technology allowed astronomers to detect them. At this point, more than five thousand such exoplanets have been identified, with the pace of discovery accelerating after the launch of NASA's Transiting Exoplanet Survey Satellite and the Webb Space Telescope. In The Little Book of Exoplanets , Princeton astrophysicist Joshua Winn offers a brief and engaging introduction to the search for exoplanets and the cutting-edge science behind recent findings. In doing so, he chronicles the dawn of a new age of discovery8212 one that has rapidly transformed astronomy and our broader understanding of the universe. Scientists now know that many Sun-like stars host their own systems of planets, some of which may resemble our solar system and include planets similar to the Earth. But, Winn tells us, the most remarkable discoveries so far have been of planets with unexpected and decidedly un-Earth-like properties, which have upended what we thought we knew about the origins of planetary systems. Winn provides an inside view of the sophisticated detective work astronomers perform as they find and study exoplanets and describes the surprising8212 sometimes downright bizarre8212 planets and systems they have found. He explains how these discoveries are revolutionizing astronomy, and he explores the current status and possible future of the search for another Earth. Finally, drawing on his own and other scientists' work, he considers how the discovery of exoplanets and their faraway solar systems changes our perspectives on the universe and our place in it. "

Rezension(3): "〈a href=http://www.publishersweekly.com target=blank〉〈img src=https://images.contentreserve.com/pw_logo.png alt=Publisher's Weekly border=0 /〉〈/a〉: May 8, 2023 In this spellbinding survey, Winn ( Photonic Crystals ), an astrophysics professor at Princeton University, proves more than up to the task of making astrophysics accessible and enjoyable for lay readers. Providing a fascinating overview of exoplanets, or planets outside our solar system, he explains that there are real-life planets that orbit two suns the way that Luke Skywalker’s home planet does in Star Wars , and that “puffball planets” have densities “comparable... to Styrofoam.” Winn highlights the strategies astronomers use to study distant cosmic bodies, describing how a planet’s mass and orbit orientation can be deduced from studying how much a star’s light dims when the planet passes in between the star and Earth, which causes an often barely perceptible eclipse. Other methods involve inferring cosmic bodies’ movements by measuring variations in the frequency of light and radio waves, as well as studying the ways in which a planet’s atmosphere absorbs and refracts starlight on its way to Earth. There’s plenty here to spark the curiosity of armchair astronomers (“It’s always raining iron” on WASP-76b, a planet twice the size of Jupiter), and plentiful diagrams help clarify the inventive methods of studying exoplanets. This inspires wonder at the eccentricities of the universe. Illus."

Content: Since it was first published in 1995, Photonic Crystals has remained the definitive text for both undergraduates and researchers on photonic band-gap materials and their use in controlling the propagation of light. This newly expanded and revised edition covers the latest developments in the field, providing the most up-to-date, concise, and comprehensive book available on these novel materials and their applications. Starting from Maxwell's equations and Fourier analysis, the authors develop the theoretical tools of photonics using principles of linear algebra and symmetry, emphasizing analogies with traditional solid-state physics and quantum theory. They then investigate the unique phenomena that take place within photonic crystals at defect sites and surfaces, from one to three dimensions. This new edition includes entirely new chapters describing important hybrid structures that use band gaps or periodicity only in some directions: periodic waveguides, photonic-crystal slabs, and photonic-crystal fibers. The authors demonstrate how the capabilities of photonic crystals to localize light can be put to work in devices such as filters and splitters. A new appendix provides an overview of computational methods for electromagnetism. Existing chapters have been considerably updated and expanded to include many new three-dimensional photonic crystals, an extensive tutorial on device design using temporal coupled-mode theory, discussions of diffraction and refraction at crystal interfaces, and more. Richly illustrated and accessibly written, Photonic Crystals is an indispensable resource for students and researchers. Extensively revised and expanded Features improved graphics throughout Includes new chapters on photonic-crystal fibers and combined index-and band-gap-guiding Provides an introduction to coupled-mode theory as a powerful tool for device design Covers many new topics, including omnidirectional reflection, anomalous refraction and diffraction, computational photonics, and much more.
