HERSCHEL, WILLIAM - THE DYNAMICAL THEORY OF STARS AND NEBULAEBiblio.com

181142810London W. Bulmer and Co. 1811 a.1814. 4to. No wrappers as extracted from "Philosophical Transactions" Year 1811-Part II. 269-336 and 2 engraved plates showing the shapes of 42 nebulae and star-clusters. And 1814 - Part I. Pp. 248-84 a. 1 engraved plate. Both fine and clean. First appearance of two milestone papers in cosmology in which Herschel demonstrates the irregular distribution of the stars in space and "for the first time recognized that the clusters in and near the Milky Way really belonged to it and were not independent systems that happened to lie in the same direction as seen by us."Berry Short History of Astronomy p. 340."In 1811 and 1814 the papers offered he published a complete theory of a possible process wherby the shining fluid consisting a diffused nebula might gradually condense - the denser portions of it being centres of attraction - first into a denser nebula or compressed star cluster then into one or more nebulous stars lastly into a single star or group of stars. Every supposed stage in this process was abundantly illustrated from records of actual nebulae and clusters which he had observed."Berry."Illustrated with many examples at every stage these papers 1811 a. 1814 showed brilliantly how dynamic changes can be inferred from virtually static evidence; and Herschel concluded by characterizing the Milky Way in its present stage of dissolution as "this mysterious chronometer". DSB VI p. 333. A paper by Henry Kater attached: "Further Experiments on the Light of the Cassegrainian telescope compared with that of the Georgian". 1814. Pp. 231-247. unknown

180345133London Bulwer and Co. 1803 a. 1804. 4to. Without wrappers as extracted from "Philosophical Transactions of the Royal Society of London." Year 1803-Part II. Pp. 339-382 and 2 engraved plates. a. Year 1804-Part II. Pp. 353-384 a. 1 engraved plate. Light browning to a few margins. 2 plates with scattered brownspots otherwise clean and wide-margined. First appearance of these fundamental paper in cosmology and physics as they contains the FIRST OBSERVATIONAL DATA TO SUPPORT THAT NEWTON'S DYNAMICAL LAWS HOLDS OUTSIDE THE SOLAR SYSTEM. Herschel shows here that the circulating motions of double-stars were under gravitational forces. Until then the validity of the law of gravity was only established within the solar system. Now a century after the establishment of the law it was traced out in the motion of incredibly distant stars and the theory first truly earned its title of Universal. The exact proof of the mutual gravitation of the double-stars was only obtained five years after Herschel's death when the motions of the stars were more precisely dtermined.One of the most notable of Herschel's discoveries of double-stars binary stars. A first cataloque of such pairs was published early in 1782 and contained 269 of which 227 were new discoveries. "Twenty years after the publication of his first cataloque Herschel was of Michell's opinion - Michell had expressed the opinion that the odds in favour of a physical relation between the members of Herschel's newly discovered double stars were "beyond arithmetic" - but was able to support it by evidence of an entirely novel and much more direct character. A series of observations of Castor presented in two papers in the "Philosophical Transaction" in 1803 and 1804 the paperS offered which were fortunately supplemented by an observation of Bradley's in 1759 had shewn a progressive alteration in the direction of the line joining its two components of such a character as to leave no doubt that the two stars were revolving round one another; and there were five oher cases in which a similar motion was observed.it was shown that the double-star was really formed by a connected pair of stars near enough to influence one another's mortion."Berry in "A Short History of Astronomy" pp. 342-43. unknown
