The Henry Draper Catalogue (HD) is an astronomical star catalogue published between 1918 and 1924, giving spectroscopic classifications for 225,300 stars; it was later expanded by the Henry Draper Extension (HDE), published between 1925 and 1936, which gave classifications for 46,850 more stars, and by the Henry Draper Extension Charts (HDEC), published from 1937 to 1949 in the form of charts ...
Lastly, the Cape Photographic Durchmusterung (450,000 stars, 1896), compiled at the Cape, South Africa, covers declinations −18 to −90. Astronomers preferentially use the HD designation (see next entry) of a star, as that catalogue also gives spectroscopic information, but as the Durchmusterungs cover more stars they occasionally fall back ...
Johnson came back with a new spending plan Thursday approved by Trump that had a two year suspension of the debt ceiling. That approach failed, despite the president-elect urging Republicans to ...
A first result of this work was the Draper Catalogue of Stellar Spectra, published in 1890. Williamina Fleming classified most of the spectra in this catalogue and was credited with classifying over 10,000 featured stars and discovering 10 novae and more than 200 variable stars. [53]
WASHINGTON (Reuters) -A group of 16 states led by California and environmental groups dropped a lawsuit filed in 2022 that sought to block the U.S. Postal Service's plan to buy mostly gas-powered ...
Israel wasted no time after Bashar al-Assad’s fall to bomb all the Syrian military assets it wanted to keep out of the rebels’ hands – striking nearly 500 targets, destroying the navy, and ...
Tide is a tool to identify peptides from tandem mass spectra. It is an independent re-implementation of the SEQUEST algorithm, which identifies peptides by comparing the observed spectra to a catalog of theoretical spectra derived in silico from a database of known proteins.
