Hosszú leírás:

You are holding in your hands, dear Reader, your passport to an exciting cosmic adventure – exploring the universe of double and multiple stars! These are the sky’s tinted jewels and waltzing couples, and they are waiting patiently in the darkness of night to dazzle and delight you. This is actually two books in one. The ?rst part surveys the current state of knowledge about double stars – how they are born, evolve and interact, their signi?cance in the cosmic scheme of things,and the valuable insights they provide into such fundamental matters as stellar masses and the ultimate fate of stars.The more we know about these fascinating objects, the more enjoyment we will ul- mately derive from actually viewing them ?rsthand with binoculars and telescopes from our gardens or backyards or ?elds.As Charles Edward Barns stated in his long out-of-print classic 1001 Celestial Wonders, Let me learn all that is known of them, Love them for the joy of loving. For,as a traveler in far countries Brings back only what he takes, So shall the scope of my foreknowledge Measure the depth of their pro?t and charm to me.

Double & Multiple Stars, and How to Observe Them is written specially for practical amateur astronomers who not only want to observe, but want to know and understand the details of exactly what they are looking at. It is a mine of information for all levels of amateur observers, from the beginner to the experienced.

The concept of the book – and of the series – is to present an up-to-date detailed description of the objects, their physics and their evolution (part one); and then (part two) to consider how to observe and record them successfully. Increasing light pollution throughout the world does not affect the viewing of double and multiple stars. More and more amateur astronomers are therefore turning to this interesting – and scientifically useful – area.

It will also be bought by those who are not practical astronomers but simply want to find out more about these unusual star systems.
