	Walter Sydney Adams Papers, American Philosophical Society
		An expert in stellar spectroscopy, Walter Sydney Adams (1876-1956) made important empirical contributions to the analysis of the physical conditions of stellar and planetary atmospheres, determining the distances to extragalactic objects, and understanding stellar evolution.
		An expert in stellar spectroscopy, Walter Sydney Adams was born of American missionary parents in the Syrian village of Kassab in 1876.
		In recognition of his efforts, Adams was elected to the American Philosophical Society in 1915, and was awarded the Gold Medal of the Royal Astronomical Society in 1917, and the Draper Medal of the National Academy of Sciences in 1918.

	Walter Sydney Adams - Wikipedia, the free encyclopedia
		Walter Sydney Adams (December 20, 1876 – May 11, 1956) was an American astronomer.
		He was born in Antioch, Syria to missionary parents, and was brought to the U.S. in 1885.
		The Adams crater on the Moon is jointly named after him, John Couch Adams and Charles Hitchcock Adams.

	Adams, Walter Sydney
		Adams was born near Antioch, Syria, and studied celestial mechanics at the University of Chicago.
		Adams was involved in a long-term project with other astronomers to determine the absolute magnitudes of stars; together, they found the value for 6,000 stars.
		Adams studied the atmosphere of Mars and Venus, reporting in 1932 the presence of carbon dioxide in the atmosphere of Venus and, in 1934, the occurrence of oxygen in concentrations of less than 0.1% on Mars.

		The Adams Prize, presented by the University of Cambridge, commemorates his prediction of the position of Neptune.
		Adams, who thought the query unessential, did not reply, and Airy for some months took no steps to verify by telescopic search the results of the young mathematician's investiation.
		Using a powerful and elaborate analysis, Adams ascertained that this cluster of meteors, which belongs to the solar system, traverses an elongated ellipse in 33 1/4 years, and is subject to definite perturbations from the larger planets, Jupiter, Saturn and Uranus.

	Adams, Walter Sidney (1876-1956)
		Adams served as director of Mount Wilson from 1923 to 1946.
		His spectroscopic studies of the Sun and stars led to the discovery, with Arnold Kohlschütter, of a spectroscopic method for finding stellar distances: they showed that the relative intensities of spectral lines could be used to determine absolute magnitudes of both giant and main sequence stars.
		Adams identified Sirius B as the first known white dwarf, and his measurement of its gravitational redshift was taken as confirming evidence for the general theory of relativity.

		Adams developed a technique for measuring the distance to stars called the 'method of spectroscopic parallaxes'.
		In 1915 Adams examined the companion star of Sirius and found that its surface is white-hot, making it the first white dwarf to be identified.
		Adams is best known for his important spectroscopic studies of the stars and planets.

		Due to Hale's illnesses, Adams was Acting Director for much of Hale's tenure, and he became the second Director of Mount Wilson from 1923 to 1946.
		Adams was hand-picked by Hale to take charge of stellar spectroscopy work at Yerkes and Mount Wilson and the younger astronomer showed tremendous loyalty to Hale and Hale's vision throughout his career.
		As Adams assumed the leadership role at Mount Wilson he concentrated on making the observatory a place where researchers worked with great freedom but maintain a high level of cooperation.

		Walter (Sydney) Adams was an American astronomer who is best known for his spectroscopic studies of sunspots, the rotation of the Sun, the velocities and distances of thousands of stars, and planetary atmospheres.
		He found (with Arnold Kohlschütter) that the relative intensities of stallar spectral lines depend on the absolute luminosities of the star, which in turn provides a spectroscopic method of determining stellar distances.By this method, he measured distances to hundreds of giant and main sequence stars.
		Adams identified Sirius B as the first white dwarf star known, and his measurement of its gravitational redshift was confirming evidence for the general theory of relativity.

	TIME.com: Moon Mirror -- Jan. 15, 1934 -- Page 1
		Adams wondered whether the lack of oxygen lines in his spectrum was due to interference by light from other gases in the Martian atmosphere.
		Adams last week told how he finessed this physical difficulty by using earthshine.
		Adams and Dunham found that the spectrum of earthshine showed three times as much oxygen as that of the moon's bright light.

	TIME.com: Farewell to Martians -- Feb. 10, 1941 -- Page 1
		Reason: Walter Sydney Adams, astute director of Mt. Wilson Observatory in California, said he had observed the Martian atmosphere for water-vapor content, found none or almost none—in any case (allowing for instrumental error) not more than 5% of the moisture in earth's air.
		This he did with the help of a phenomenon called the Doppler effect: when a source of light approaches earth, its spectrum lines are shifted to the right, and when it is receding they are shifted to the left.
		Years ago Dr. Adams found that the oxygen content of the Martian atmosphere must be less than 1 % of that in earth's air (TIME, Jan. 15, 1934).
