Absolute magnitude
In astronomy, absolute magnitude is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale.
See N Centauri and Absolute magnitude
Angular distance
Angular distance or angular separation is the measure of the angle between the orientation of two straight lines, rays, or vectors in three-dimensional space, or the central angle subtended by the radii through two points on a sphere.
See N Centauri and Angular distance
Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.
See N 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. N Centauri and b-type main-sequence star are b-type main-sequence stars.
See N Centauri and B-type main-sequence star
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 N Centauri and Binary star
Carl Ludwig Christian Rümker
Carl Ludwig Christian Rümker (28 May 1788 – 21 December 1862) was a German astronomer.

Centaurus
Centaurus is a bright constellation in the southern sky.
Constellation
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object.
See N Centauri and Constellation
F-type main-sequence star
An F-type main-sequence star (F V) is a main-sequence, hydrogen-fusing star of spectral type F and luminosity class V. These stars have from 1.0 to 1.4 times the mass of the Sun and surface temperatures between 6,000 and 7,600 K. N Centauri and f-type main-sequence star are f-type main-sequence stars.
See N Centauri and F-type main-sequence star
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.
Position angle
In astronomy, position angle (usually abbreviated PA) is the convention for measuring angles on the sky.
See N Centauri and Position angle
Radial velocity
The radial velocity or line-of-sight velocity of a target with respect to an observer is the rate of change of the vector displacement between the two points.
See N Centauri and Radial velocity
Scorpius–Centaurus association
The Scorpius–Centaurus association (sometimes called Sco–Cen or Sco OB2) is the nearest OB association to the Sun. N Centauri and Scorpius–Centaurus association are Centaurus.
See N Centauri and Scorpius–Centaurus association
Spectral line
A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum.
See N Centauri and Spectral line
Stellar classification
In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
See N Centauri and Stellar classification
Stellar parallax
Stellar parallax is the apparent shift of position (parallax) of any nearby star (or other object) against the background of distant stars.
See N Centauri and Stellar parallax
Sun
The Sun is the star at the center of the Solar System.
The Astronomical Journal
The Astronomical Journal (often abbreviated AJ in scientific papers and references) is a peer-reviewed monthly scientific journal owned by the American Astronomical Society (AAS) and currently published by IOP Publishing.
