Apparent magnitude

Apparent magnitude is a measure of the brightness of a star or other astronomical object.

See H Centauri and Apparent magnitude

B-type main-sequence star

A B-type main-sequence star (B V) is a main-sequence (hydrogen-burning) star of spectral type B and luminosity class V. These stars have from 2 to 16 times the mass of the Sun and surface temperatures between 10,000 and 30,000 K. B-type stars are extremely luminous and blue. H Centauri and b-type main-sequence star are b-type main-sequence stars.

See H Centauri and B-type main-sequence star

Bayer designation

A Bayer designation is a stellar designation in which a specific star is identified by a Greek or Latin letter followed by the genitive form of its parent constellation's Latin name.

See H Centauri and Bayer designation

Binary star

A binary star or binary star system is a system of two stars that are gravitationally bound to and in orbit around each other.

See H Centauri and Binary star

Boss General Catalogue

Boss General Catalogue (GC, sometimes General Catalogue) is an astronomical catalogue containing 33,342 stars.

See H Centauri and Boss General Catalogue

Bright Star Catalogue

The Bright Star Catalogue, also known as the Yale Catalogue of Bright Stars, Yale Bright Star Catalogue, or just YBS, is a star catalogue that lists all stars of stellar magnitude 6.5 or brighter, which is roughly every star visible to the naked eye from Earth. H Centauri and bright Star Catalogue are bright Star Catalogue objects.

See H Centauri and Bright Star Catalogue

Cape Photographic Catalogue

The Cape Photographic Catalogue (CPC) is a star catalogue containing 68,467 stars in the Southern Hemisphere whose declinations are either between −30° and −40° or between −52° and −90°.

See H Centauri and Cape Photographic Catalogue

Centaurus

Centaurus is a bright constellation in the southern sky.

See H Centauri and Centaurus

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.

See H Centauri and Durchmusterung

General Catalogue of Stellar Radial Velocities

The General Catalogue of Stellar Radial Velocities is a star catalogue which lists radial velocities for 15,107 stars.

See H Centauri and General Catalogue of Stellar Radial Velocities

Guide Star Catalog

The Guide Star Catalog (GSC), also known as the Hubble Space Telescope, Guide Catalog (HSTGC), is a star catalog compiled to support the Hubble Space Telescope with targeting off-axis stars.

See H Centauri and Guide Star Catalog

Henry Draper Catalogue

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. H Centauri and Henry Draper Catalogue are Henry Draper Catalogue objects.

See H Centauri and Henry Draper Catalogue

Hipparcos

Hipparcos was a scientific satellite of the European Space Agency (ESA), launched in 1989 and operated until 1993.

See H Centauri and Hipparcos

Light curve

In astronomy, a light curve is a graph of the light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the y-axis and with time on the x-axis.

See H Centauri and Light curve

Light-year

A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi.

See H Centauri and Light-year

Orbital inclination

Orbital inclination measures the tilt of an object's orbit around a celestial body.

See H Centauri and Orbital inclination

Orbital period

The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object.

See H Centauri and Orbital period

Parallax

Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight and is measured by the angle or half-angle of inclination between those two lines.

See H Centauri and Parallax

Parsec

The parsec (symbol: pc) is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to or (AU), i.e..

See H Centauri and Parsec

PPM Star Catalogue

The PPM Star Catalogue (Positions and Proper Motions Star Catalogue) is the successor of the SAO Catalogue.

See H Centauri and PPM Star Catalogue

Rotating ellipsoidal variable

Rotating ellipsoidal variables are a class of close binary variable star systems whose components are ellipsoidal. H Centauri and Rotating ellipsoidal variable are Rotating ellipsoidal variables.

See H Centauri and Rotating ellipsoidal variable

Scorpius–Centaurus association

The Scorpius–Centaurus association (sometimes called Sco–Cen or Sco OB2) is the nearest OB association to the Sun. H Centauri and Scorpius–Centaurus association are Centaurus.

See H Centauri and Scorpius–Centaurus association

Smithsonian Astrophysical Observatory Star Catalog

The Smithsonian Astrophysical Observatory Star Catalog is an astrometric star catalogue, created by Smithsonian Institution, a research institute.

See H Centauri and Smithsonian Astrophysical Observatory Star Catalog

Solar radius

Solar radius is a unit of distance used to express the size of stars in astronomy relative to the Sun.

See H Centauri and Solar radius

Star system

A star system or stellar system is a small number of stars that orbit each other, bound by gravitational attraction.

See H Centauri and Star system

Stellar classification

In astronomy, stellar classification is the classification of stars based on their spectral characteristics.

See H Centauri and Stellar classification

Transiting Exoplanet Survey Satellite

Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission.

See H Centauri and Transiting Exoplanet Survey Satellite

Variable-star designation

In astronomy, a variable-star designation is a unique identifier given to variable stars. H Centauri and variable-star designation are objects with variable star designations.
