Henry Draper Catalogue, the Glossary

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, which gave classifications for 86,933 more stars.^[1]

Annie Jump Cannon

Annie Jump Cannon (December 11, 1863 – April 13, 1941) was an American astronomer whose cataloging work was instrumental in the development of contemporary stellar classification.

Antonia Maury

Antonia Caetana de Paiva Pereira Maury (March 21, 1866 – January 8, 1952) was an American astronomer who was the first to detect and calculate the orbit of a spectroscopic binary.

Astronomical catalog

An astronomical catalog or catalogue is a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery.

Astronomy

Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos.

Carbon star

A carbon star (C-type star) is typically an asymptotic giant branch star, a luminous red giant, whose atmosphere contains more carbon than oxygen.

CD-ROM

A CD-ROM (compact disc read-only memory) is a type of read-only memory consisting of a pre-pressed optical compact disc that contains data computers can read—but not write or erase—CD-ROMs.

Centre de données astronomiques de Strasbourg

The Centre de Données astronomiques de Strasbourg (CDS; English translation: Strasbourg Astronomical Data Centre) is a data centre which collects and distributes astronomical information.

Durchmusterung

In astronomy, Durchmusterung or Bonner Durchmusterung (BD) is an astrometric star catalogue of the whole sky, published by the Bonn Observatory in Germany from 1859 to 1863, with an extension published in Bonn in 1886. Henry Draper Catalogue and Durchmusterung are astronomical catalogues of stars.

Peru

Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the south and west by the Pacific Ocean. Peru is a megadiverse country with habitats ranging from the arid plains of the Pacific coastal region in the west to the peaks of the Andes mountains extending from the north to the southeast of the country to the tropical Amazon basin rainforest in the east with the Amazon River.

Photographic magnitude

Photographic magnitude is a measure of the relative brightness of a star or other astronomical object as imaged on a photographic film emulsion with a camera attached to a telescope.

See Henry Draper Catalogue and Photographic magnitude

Right ascension

Right ascension (abbreviated RA; symbol) is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the (hour circle of the) point in question above the Earth.

Slitless spectroscopy

Slitless spectroscopy is spectroscopy done without a small slit to allow only light from a small region to be diffracted.

Southern Hemisphere

The Southern Hemisphere is the half (hemisphere) of Earth that is south of the Equator.

Spectral line

A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum.

Spectroscopy

Spectroscopy is the field of study that measures and interprets electromagnetic spectra.

Spectrum

A spectrum (spectra or spectrums) is a condition that is not limited to a specific set of values but can vary, without gaps, across a continuum.
