| dbo:abstract | Alastair Graham Walter Cameron (21. června 1925, Winnipeg, Manitoba, Kanada – 3. října 2005, Tucson, Arizona, USA) byl kanadský astrofyzik. K jeho nejznámější práci patří teorie nukleosyntézy, zejména vznik nestabilního technecia v jádru červených obrů a zánik původní atmosféry Země. Svou činností významně ovlivnil americký planetární výzkum. Alastair Cameron se narodil v roce 1925 v kanadském městě Winnipeg. Po studiu v Manitobě a Saskatchewanu emigroval v roce 1959 do USA, kde působil v Kalifornském technologickém institutu, Goddard Institute for Space Studies a . V roce 1973 se stal profesorem astronomie na Harvardu a zůstal zde 26 let. Mimoto byl v období 1976 až 1982 předsedou Space Science Board v Národní akademii věd USA.

(ar) Alastair G. W. (Graham Walter) Cameron (21 June 1925 – 3 October 2005) was an American-Canadian astrophysicist and space scientist who was an eminent staff member of the Astronomy department of Harvard University. He was one of the founders of the field of nuclear astrophysics, advanced the theory that the Moon was created by the giant impact of a Mars-sized object with the early Earth, and was an early adopter of computer technology in astrophysics. (en) Alastair Graham Walter Cameron (* 21. Juni 1925 Winnipeg, Manitoba, Kanada; † 3. Oktober 2005 in Tucson, Arizona, USA), war ein Astrophysiker. Zu seinen bekanntesten Arbeiten gehören Theorien über Nukleosynthese, insbesondere die Bildung des instabilen Elementes Technetium im Kern von Roten Riesen, sowie über das Verschwinden der ursprünglichen Atmosphäre der Erde. Der öffentliche Einsatz von Cameron beeinflusste den Kurs des US-Planeten-Forschungsprogramms über die letzten Jahrzehnte. Alastair Cameron wurde 1925 in der kanadischen Stadt Winnipeg geboren. Nach seiner Ausbildung in Manitoba und Saskatchewan emigrierte er 1959 in die USA, wo er Posten am California Institute of Technology, dem Goddard Institute for Space Studies und an der Yeshiva University in New York erhielt. Im Jahr 1973 wurde er Professor für Astronomie an der Harvard University und blieb dort 26 Jahre lang. Cameron war ferner von 1976 bis 1982 Vorsitzender des Space Science Board of the National Academy of Sciences. 1972 wurde er Fellow der American Physical Society, 1974 wurde er in die American Academy of Arts and Sciences gewählt, 1976 in die National Academy of Sciences. Cameron starb 2005 an Herzversagen.

L'astéroïde (2980) Cameron porte son nom. (fr) アルステア・キャメロン（Alastair Graham Walter Cameron、1925年6月21日 - 2005年10月3日）はカナダの天体物理学者である。 マニトバ州ウィニペグに生物学者の息子に生まれた。マニトバ大学、サスカチュワン大学で学んだ後、1959年にアメリカ合衆国に移り、カリフォルニア工科大学、ゴダード宇宙飛行センター、イェシーバー大学(Yeshiva University)で働いた。 1973年にハーヴァード大学の天文学の教授となった。1976年から1982年の間はアメリカ科学アカデミーの宇宙科学委員会の委員長を務めた。 小惑星(2904)Cameronに命名された。 (ja) Alastair Graham Walter Cameron (Winnipeg, 21 giugno 1925 – 3 ottobre 2005) è stato un fisico e astronomo canadese. Studiò all' e all'. Nel 1973 divenne insegnante di astronomia all'Università Harvard, della quale divenne nel 1999 Professore Emerito. Fu un pioniere della teoria della nucleosintesi stellare, la produzione degli elementi chimici all'interno delle stelle. Si occupò anche dei meccanismi di formazione del sistema solare. Avanzò l'ipotesi, oggi la più accredidata, che la Luna sia diventata un satellite della Terra in seguito all'impatto del nostro pianeta con un altro corpo di dimensioni paragonabili a Marte. Era un grande sostenitore della possibilità che la gran maggioranza delle stelle possieda un sistema planetario, sostenendo, diversamente da Otto Struve, che anche le stelle con alta velocità di rotazione possano avere sistemi planetari. Insieme a Frank Drake e Carl Sagan, è stato uno dei più convinti sostenitori del progetto SETI. Nel 1997 la American Astronomical Society gli assegnò il premio Henry Norris Russell Lectureship. Nel 1994 gli è stata assegnata la Medaglia Leonard . Una sua foto è visibile qui.

Foi membro do Departamento de Astronomia da Harvard University. Cameron, filho de um bioquímico canadense, nasceu em Winnipeg. Obteve o bacharelado na University of Manitoba e o doutorado na Universidade de Saskatchewan. Foi um dos pioneiros na teoria da nucleossíntese estelar – a produção de elementos químicos nas estrelas. Ele também foi o primeiro a propor que a formação da Lua resultou do impacto de um corpo do tamanho de Marte com a Terra primitiva (pt) |
