Adams, Walter Sydney (Adams, Walter Sydney) (1876-1956), American astronomer. Born December 20, 1876 in Antioch, Syria (now Antakya, Turkey). He graduated from Dartmouth College, then University of Chicago (1900), studied at Munich University and Columbia University. He taught astronomy at the University of Chicago, in 1901-1904 worked at Yerkes Observatory in 1904-1909 was an assistant astronomer at the observatory of Mount Wilson, in 1923-1946 - its director. Following the resignation of continued research in the Laboratory. Dzh.Heyla in Pasadena.
The focus of Adams was spectroscopy of stars and planets. In 1913-1916, together with A. Kolshyutterom he substantiated the spectral criteria of absolute values (ie. Undertook extensive research to determine radial velocities and spectroscopic parallaxes of stars, as well as their spectral classification. In 1925 at the request of A. Eddington performed a very complicated investigation of the spectrum of the white dwarf Sirius B with the aim of detecting the gravitational redshift of lines predicted by general relativity. In 1906-1908 determined the speed of rotation of the Sun, measured the Doppler shift of lines on the edge of the disc at different latitudes. In 1925-1934 identified the content of water vapor and oxygen in the atmosphere of Mars, discovered the carbon dioxide in the atmosphere of Venus, the presence of heavy elements (in particular, iron) in the interstellar gas.
Adams was awarded medals of various astronomical societies, was a member of many academies of sciences.
