James B. Pollack (July 9, 1938 – June 13, 1994) was an American astrophysicist who worked for NASA's Ames Research Center. Pollack was born on 9 July 1938, and was brought up in Woodmere, Long Island by a Jewish family that was in the women's garment business. He was a high school valedictorian and graduated from Princeton University in 1960. He then received his master's in nuclear physics at University of California, Berkeley in 1962 and his Ph.D from Harvard in 1965, where he was a student of Carl Sagan.〔Davidson, Keay (1999). ''Carl Sagan A Life'', John Wiley & Sons ISBN 0-471-39536-6 (This book is dedicated to Pollack)〕 He was openly gay. Dorion Sagan told how his father came to the defense of Pollack's lover in a problem with obtaining treatment at the university health service emergency room.〔Keay Davidson, Carl Sagan ''Carl Sagan : a life'', 1999, p. 245-246〕 Pollack specialized in atmospheric science,〔(【引用サイトリンク】 title=James B. Pollack, NASA Ames Hall of Fame )〕 especially the atmospheres of Mars and Venus. He investigated the possibility of terraforming Mars, the extinction of the dinosaurs and the possibility of nuclear winter since the 1980s with Christopher McKay and Sagan.〔(【引用サイトリンク】 title=Pale Blue Dot )〕 The work of Pollack et al. (1996) on the formation of giant planets ("core accretion paradigm") is seen today as the standard model.〔(【引用サイトリンク】 title=Core Accretion Model )〕 He explored the weather on Mars using data from the Mariner 9 spacecraft and the Viking mission. On this he based ground-breaking computer simulations of winds, storms, and the general climate on that planet. An overview of Pollack's scientific vita is given in the memorial talk "James B. Pollack: A Pioneer in Stardust to Planetesimals Research" 〔(【引用サイトリンク】 title=James B. Pollack: A Pioneer in Stardust to Planetesimals Research )〕 held at an Astronomical Society of the Pacific 1996 symposium. He was a recipient of the Gerard P. Kuiper Prize in 1989 for outstanding lifetime achievement in the field of planetary science. Pollack died in 1994 from a rare form of spinal cancer, at age 55. A crater on Mars was named in his honor. == External links == * (Short biography ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「James B. Pollack」の詳細全文を読む スポンサード リンク
