Takeshi Oka (岡 武史, Oka Takeshi, born 1932), FRS FRSC, is a Japanese-American chemist and astronomer specializing in the field of galactic astronomy, known as the pioneer of astrochemistry and the discoverer of extraterrestrial trihydrogen cation (H+
3).[3]
He is now R.A. Milliken Distinguished Service Emeritus Professor, Departments of Astronomy and Astrophysics, Chemistry; Enrico Fermi Institute; and the College of University of Chicago.[4]
Education
Oka was born in Tokyo, Japan, on 1932. He received his BS and PhD degree in 1955 and 1960, respectively, from the University of Tokyo.[2]
Career
In 1963, Oka working as a postdoctoral fellow with Harry Kroto at Gerhard Herzberg's laboratory,[5] National Research Council of Canada. Among them, Kroto and Herzberg have won the Nobel Prize in Chemistry, furthermore, the Nobel laureate Robert Curl was also Oka's colleague.[6]
From 1960 to 1963, Oka appointed a fellow at JSPS, the University of Tokyo. Afterward, he was successively worked at Herzberg Institute of Astrophysics (1963-1981), and the University of Chicago (1981-).[2]
In 1980, Oka discovered the infrared spectrum of H+
3, and revealed that "molecular clouds" are the birthplace of stars and that the chemical evolution of the clouds is a crucial step in star formation.[3]
Currently, Oka group's studies specializing in the field of the quantum mechanics and dynamics of fundamental molecular ions and their behavior in astronomical objects.[2]
Honors and awards[2]
Oka was on the list of ChemBank's prediction for the 2015 Nobel Prize in Chemistry.[7]
