  • Variable Star
    Variable star A variable star is a star whose brightness as seen from Earth (its apparent magnitude) fluctuates. This variation may be caused by a change in emitted light or by something partly blocking the light, so variable stars are classified as either: Intrinsic variables, whose luminosity actually changes; for example, because the star periodically swells and shrinks. Extrinsic variables, whose apparent changes in brightness are due to changes in the amount of their light that can reach Earth; for example, because the star has an orbiting companion that sometimes Trifid Nebula contains Cepheid variable stars eclipses it. Many, possibly most, stars have at least some variation in luminosity: the energy output of our Sun, for example, varies by about 0.1% over an 11-year solar cycle.[1] Contents Discovery Detecting variability Variable star observations Interpretation of observations Nomenclature Classification Intrinsic variable stars Pulsating variable stars Eruptive variable stars Cataclysmic or explosive variable stars Extrinsic variable stars Rotating variable stars Eclipsing binaries Planetary transits See also References External links Discovery An ancient Egyptian calendar of lucky and unlucky days composed some 3,200 years ago may be the oldest preserved historical document of the discovery of a variable star, the eclipsing binary Algol.[2][3][4] Of the modern astronomers, the first variable star was identified in 1638 when Johannes Holwarda noticed that Omicron Ceti (later named Mira) pulsated in a cycle taking 11 months; the star had previously been described as a nova by David Fabricius in 1596. This discovery, combined with supernovae observed in 1572 and 1604, proved that the starry sky was not eternally invariable as Aristotle and other ancient philosophers had taught.

In the intervening years the Journal has undergone a variety of changes. In 1970 the National Newsletter was published along with the Journal, being bound with the regular pages of the Journal. In 1978 the National Newsletter was physically separated but still included with the Journal, and in 1989 it became simply the Newsletter/Bulletin and in 1991 the Bulletin. That continued until the eventual merger of the two publications into the new Journal in 1997.

  • Observing Variable Stars with Binoculars
    OBSERVING VARIABLE STARS - -WITH BINOCULARS by K.E.,Chilton,F.R.A.S. A Centennial Observatory Publication. public price 50¢ Price to RASC Members 35¢ Introduction This booklet is not intended to be a technical treatise on variable stars. Nor is it for the serious amateur astronomer whose instruments and capabilities carry him far beyond what is to follow. Rather, I intend this to be read and used by the beginner, equipped only with hie eyes and a pair of binoculars. The information contained herein has been gathered from many sources, including my own experience. I da not pretend, however, to be an expert on variable star observing. I write this only as a guide to those who follow, so that they may avoid some of the pitfalls involved in variable star observing.Hopefully, this booklet will enable the beginner to make a start, make a few observations, and progress into more serious work. My own equipment, aside from the telescopes housed in the observatory, consists of a pair of 7x50 binoculars, which I use to observe many of the stars mentioned herein. The only other equip- ment needed is a wrist watch, a flashlight, a comfortable lawn chair, some warm clothing, a pencil, this booklet, and the desire to learn and see something different! I wish the reader good fortune and clear skies for his debut in the field of variable star observing with binoculars. K.E.Chilton Chapter 1 Why Observe Variable Stars? Have you ever stood in the quiet solitude by a northern lake on a moonless summer night while an orchestra of crickets played their favourite symphony and myriads of stare reflected off the calm water ? Have you ever lain on your back, gazing up at the seemingly countless points of light and wondered if shepherds,long ago, had done the same ? If you watch those stars for hours and hours, you may never see a change, and if you watch them for years and years, you may be almost certain that the stars looked the same to those ancient shepherds as they do to you now.

  • The COLOUR of CREATION Observing and Astrophotography Targets “At a Glance” Guide
    The COLOUR of CREATION observing and astrophotography targets “at a glance” guide. (Naked eye, binoculars, small and “monster” scopes) Dear fellow amateur astronomer. Please note - this is a work in progress – compiled from several sources - and undoubtedly WILL contain inaccuracies. It would therefor be HIGHLY appreciated if readers would be so kind as to forward ANY corrections and/ or additions (as the document is still obviously incomplete) to: [email protected]. The document will be updated/ revised/ expanded* on a regular basis, replacing the existing document on the ASSA Pretoria website, as well as on the website: coloursofcreation.co.za . This is by no means intended to be a complete nor an exhaustive listing, but rather an “at a glance guide” (2nd column), that will hopefully assist in choosing or eliminating certain objects in a specific constellation for further research, to determine suitability for observation or astrophotography.
