Hyron spin wheel

from Wikipedia, the free encyclopedia

Hyron Spinrad (born February 17, 1934 in New York City , † December 7, 2015 ) was an American astronomer .

Spinrad studied at the University of California, Berkeley , where he received his PhD in 1961, on star populations in galaxy nuclei. He was then a Senior Scientist at the Jet Propulsion Laboratory before becoming Assistant Professor in 1964 and Professor of Astronomy at Berkeley in 1968.

Spinrad studied the atmosphere of planets in the solar system at the Jet Propulsion Laboratory, and in 1963 discovered water vapor in the Martian atmosphere and determined its carbon dioxide content.

In the 1970s he researched galaxies from the third Cambridge catalog of radio sources with high redshifts and was the first to discover galaxies with redshift z> 1 in 1975. He also found that there were ( ) considerably more (factor ) radio galaxies then than today.

In 1986 he received the Dannie Heineman Prize for Astrophysics . In 1991 an asteroid was named after him: (3207) spin wheel . He had been a member of the National Academy of Sciences since 1988 .
