Astronomical systems

Ebook "Schaum's outline of Theory and problems of Astronomy" is to serve as a supplement to a basic astronomy text. Much of the material here is abbreviated, and students should use this book as a guide to the key concepts in modern astronomy, but not as an all-inclusive resource. Topics covered range from planetary astronomy to cosmology, in the modern context. The first chapter covers most of the phsyics required to obtain a basic understanding of astronomical phenomena.

Ebook "Observational astrophysics (Third edition)" focuses on fundamental and sometimes practical limitations on the ultimate performance that an astronomical system may reach, rather than presenting particular systems in detail. Avoiding particulars, it covers the whole of the electromagnetic spectrum, and provides an introduction to the new forms of astronomy becoming possible with gravitational waves and neutrinos. It also treats numerical aspects of observational astrophysics: signal processing, astronomical databases and virtual observatories.

An attempt has been made in these pages to trace the evolution of intellectual thought in the progress of astronomical discovery, and, by recognising the different points of view of the different ages, to give due credit even to the ancients. No one can expect, in a history of astronomy of limited size, to find a treatise on "practical" or on "theoretical astronomy," nor a complete "descriptive astronomy," and still less a book on "speculative astronomy.

The Observatory carries out front-line astronomical research in three key areas of astrophysics, namely: Solar-System Science, Solar Physics, and Stellar and Galactic Astrophysics. Solar-System research en- compasses the dynamical structure, evolution and origin of objects in the inner and outer solar system and comparative planetology and meteor physics.

Discovering what lies behind a hill or beyond a neighborhood can be as simple as taking a short walk. But curiosity and the urge to make new dis- coveries usually require people to undertake journeys much more adven- turesome than a short walk, and scientists oft en study realms far removed from everyday observation—sometimes even beyond the present means of travel or vision.

A multitude of measurement units exist within astronomy, some of which are unique to the subject, causing discrepancies that are particularly apparent when astronomers collaborate with other disciplines in science and engineering. The International System of Units (SI) is based on a set of seven fundamental units from which other units may be derived. However, many astronomers are reluctant to drop their old and familiar systems. This handbook demonstrates the ease with which transformations from old units to SI units may be made.

Four hundred years ago, the Universe changed. Or, at least, our perception of it did, thanks to Galileo Galilei’s scrutiny of the night sky with a telescope. Within a couple of years, his observations of the Moon, phases of Venus and satellites of Jupiter shattered the old Ptolemaic model of our Solar System. To the church’s dismay, Earth assumed its rightful place as one of several planets orbiting the Sun (see page 28). Marking Galileo’s anniversary, the International Year of Astronomy seeks to remind us of the humbling nature of gazing at the heavens.

Astronomers have studied the heavens for more than two millennia, but in the twentieth century, humankind ventured off planet Earth into the dark vacuum void of space, forever changing our perspective of our home planet and on our relationship to the universe in which we reside. Our explorations of space—the final frontier in our niche in this solar system—first with satellites, then robotic probes, and finally with humans, have given rise to an extensive space industry that has a major influence on the economy and on our lives. In 1998, U.S.

Humans have been exploring their world for thousands of years. People love to discover and learn about new places. Some of today's explorers are making exciting new discoveries in space. Many objects are found in the universe. These include asteroids, planets, moons, comets, and stars. Astronomers are scientists who study the objects in space. People who travel to space to learn about it are called astronauts.

In 140 A.D. a Greek astronomer named Ptolemy wrote that the Earth was the center of the universe. He thought all the stars, the Sun, and the Moon revolved around it. This made sense because that is how things looked in the sky from Earth. We call Ptolemy’s theory the geocentric view. It is derived from geo (Earth) and centric (center). Astronomers believed the geocentric view for 1,500 years until 1543. The Heliocentric View About 500 years ago, Copernicus found that the Earth and other planets revolve around the Sun. His theory was published in1543.

We present the proceedings from the workshop entitled Scientific Detectors for Astronomy 2005, a weeklong meeting held in Taormina, Sicily during 19-25 June 2005. This was the sixth workshop of this series, and the fourth with hardcover proceedings. By all measures, this workshop surpassed the previous meetings. The primary purpose of any technical meeting is the exchange of scientific and engineering information.

This book is dedicated to the memory of Gisèle Mersch whose life ended prematurely in June 2002. Back in the 1970s, when few people were using them, Gisèle introduced me to the arcane secrets of then advanced multivariate statistical methodologies. I was already involved in more classical statistical studies undertaken at Paris Observatory with Jean Jung: developing and applying maximumlikelihood algorithms to stellar photometric and kinematic data in order to derive absolute luminosities, distances and velocities in the solar neighborhood....
