No Binding. Condizione: Fine. Michael Mark Woolfson, "A Capture Theory, of the Origin of the Solar System" in Proceedings of the Royal Society of London, Series A, 1964 vol 282. The Woolfson appears on pp 485-505in the full bound volume of iv, 596pp. [++] Finely and newly rebound in cloth-backed marbled boards, with new endpapers. Fine copy. The binding and boards have been antiqued by the bookbinder so that the volume doesn't have the biblio-equivalent of that "new car smell". Really, though, the binder did a fabulous job with this.[++] The abstract of the Woolfson (1927-2021) paper is actually very concise and sums up the paper quite nicelynamely that a protostar or some such came into close proximity with what would become our Sun, but was ripped apart the remnants of which became our planets and then forming into our very own solar system. So:--"Abstract: A theory of the origin of the Solar System is described which involves the capture of material from a light diffuse star which passed close to the Sun. It is shown that planetary condensations could be formed and that these would take up orbits with radii having the required range of values." [++] "[Woolfson's] position in Manchester required that [he] teach a variety of courses, and this helped stimulate his interest in other areas of physics. An astronomy textbook discussed theories on the origin of the Solar System, none of which seemed completely satisfactory, so Michael designed a model that he christened the Capture theory. It invoked a mechanism for the formation of the Solar System involving a tidal interaction between a condensed Sun and a collapsing protostar with the capture of protostar material by the Sun. The hypothesis was tested by computer modeling and found to be plausible."Biographical Memoirs of the Fellows of the Royal Society, vol 71, December 2021.

1st Edition. HANDSOME FIRST EDITION OF MICHAEL WOOLFSON'S CAPTURE THEORY, PROPOSING THAT THE SOLAR SYSTEM FORMED THROUGH THE CAPTURE OF MATERIAL FROM A DIFFUSE STAR THAT PASSED CLOSE TO THE SUN. "In 1964, a capture theory of the origin of the solar system was put forward by Woolfson. It was proposed that the Sun could have captured planetary material from a light, diffuse star by tidal forces during an encounter, and it was shown that for some set of parameters the captured material could take up a range of orbits around the Sun with perihelia comparable to those observed in the solar system. "The condensation of planets from the captured material was investigated according to the theory of the formation of condensations in a gaseous filament, as given by Jeans (1919), and it was shown that the ejected filament may have been sufficiently dense to have given rise to planets" (Dormand, The Capture Theory and Planetary Condensation, Monthly Notices of the Royal Astronomical Society, Vol. 151, 1971, p. 307). CONDITION & DETAILS: London: The Royal Society. Complete volume. 4to. 9.75 by 7 inches (213 x 138mm). [4], 596, [4]. The volume is illustrated throughout with in-text figures and plates; the Woolfson paper has many in-text illustrations. Handsomely rebound; gilt lettered at the spine. The marbled paper boards were purposefully scuffed by the binder in order that the book, though rebound, appears somewhat aged. Solidly and very tightly bound. Bright and clean throughout. Fine condition.
