The Catalog of Components of Double and Multiple Stars, or CCDM, is an astrometric star catalogue of double and multiple stars. It was made by Jean Dommanget and Omer Nys at the Royal Observatory of Belgium in order to provide an input catalogue of stars for the Hipparcos mission. The published first edition of the catalog, released in 1994, has entries for 74,861 components of 34,031 double and multiple stars; the second edition, in 2002, has been expanded to provide entries for 105,838 components of 49,325 double and multiple stars. The catalog lists positions, magnitudes, spectral types, and proper motions for each component.
Famous quotes containing the words components, double, multiple and/or stars:
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
“I grew up confidently expecting to have a profession and earn my own living, and also confidently expecting to be married and have children. It was fifty-fifty with me. I was just as passionately determined to have children as I was to have a career. And my mother was the triumphant answer to all doubts as to the success of this double role. From my earliest memory she had more than half supported the family and yet she was supremely a mother.”
—Crystal Eastman (1881–1928)
“... the generation of the 20’s was truly secular in that it still knew its theology and its varieties of religious experience. We are post-secular, inventing new faiths, without any sense of organizing truths. The truths we accept are so multiple that honesty becomes little more than a strategy by which you manage your tendencies toward duplicity.”
—Ann Douglas (b. 1942)
“The day in his hotness,
The strife with the palm;
The night in her silence,
The stars in their calm . . .”
—Matthew Arnold (1822–1888)
