Cataclysmic Cosmic Events and How to Observe Them

This book is about observing dramatic cosmic events. You might think that the observation of gamma ray bursts, cataclysmic variable star outbursts, distant supernovae, and active galactic nuclei are beyond the range of amateurs - but this is not the case.

In the Victorian era or for non-British readers, the mid-to-late nineteenth century amateur astronomy tended to center on Solar System objects. The Moon and planets, as well as bright comets, were the key objects of interest. The brighter variable stars were monitored, but photography was in its infancy and digital imaging lay a century in the future. Today, at the start of the twenty-first century, amateurs are better equipped than any professionals of the mid-twentieth century, let alone the nineteenth. An amateur equipped with a 30-cm telescope and a CCD camera can easily image objects below magnitude 20 and, from very dark sites, 22 or 23. Such limits would have been within the realm of the 100- and 200-inch reflectors on Mount Wilson and Mount Palomar in the 1950s, but no other observatories. However, even those telescopes took hours to reach such limits, and then the photographic plates had to be developed, fixed, and examined by eye. In the modern era digital images can be obtained in minutes and analyzed 'on the fly' while more images are being downloaded. Developments can be e-mailed to other interested amateurs in real time, during an observing session, so that when a cataclysmic event takes place amateurs worldwide know about it. As recently as the 1980s, even professional astronomers could only dream of such instantaneous communication and proc- sing ability.

Introduces some of the most bizarre and exciting events in the universe Discusses the events themselves, and what we know of their physics Enables backyard astronomers to observe these events and take part in cutting-edge science Explains, in a clear style, how to contribute results to professional astronomers

Klappentext

ASTRONOMERS' OBSERVING GUIDES provide up-to-date information for amateur astronomers who want to know all about what it is they are observing. This is the basis of the first part of the book. The second part details observing techniques for practical astronomers, working with a range of different instruments.

This book invites you to observe the most spectacular, high-energy events taking place in the cosmos. Even though these events may occur hundreds, thousands, millions or even billions of light-years away, you can witness them using the naked eye, binoculars, or telescopes. The book covers cataclysmic variable stars (CV's), novae and dwarf novae, recurrent novae, solar flares, flare stars and prominences as well as the more distant supernovae, hypernovae, blazars, quasars, and gamma ray bursters. There are also sections on photometry, equipment, and software as well as many valuable observing tips based on the author's own experience viewing these events.

For the amateur astronomer who is ready to leave the confines of the Solar System and look out into deep space, this book offers a variety of exciting challenges and suggestions enabling you to contribute real scientific data on high energy outbursts and cataclysmic cosmic events with just your backyard telescope and a bit of know-how.
