Apparent magnitude

The apparent magnitude of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth.

Binary star

A binary star is a star system consisting of two stars orbiting around their common barycenter.

Centaurus

Centaurus is a bright constellation in the southern sky.

Constellation

A constellation is a group of stars that are considered to form imaginary outlines or meaningful patterns on the celestial sphere, typically representing animals, mythological people or gods, mythological creatures, or manufactured devices.

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.Tables VII and VIII.

Giant star

A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature.

Light-year

The light-year is a unit of length used to express astronomical distances and measures about 9.5 trillion kilometres or 5.9 trillion miles.

Minute and second of arc

A minute of arc, arcminute (arcmin), arc minute, or minute arc is a unit of angular measurement equal to of one degree.

Nuclear fusion

In nuclear physics, nuclear fusion is a reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles (neutrons or protons).

Orbital eccentricity

The orbital eccentricity of an astronomical object is a parameter that determines the amount by which its orbit around another body deviates from a perfect circle.

Orbital period

The orbital period is the time a given astronomical object takes to complete one orbit around another object, and applies in astronomy usually to planets or asteroids orbiting the Sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars.

Radial velocity

The radial velocity of an object with respect to a given point is the rate of change of the distance between the object and the point.

Solar core

The core of the Sun is considered to extend from the center to about 0.2 to 0.25 of solar radius.

South African Astronomical Observatory

South African Astronomical Observatory (SAAO) is the national centre for optical and infrared astronomy in South Africa.

Stellar classification

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

New!!: 1 Centauri and Stellar classification · See more »

Stellar evolution

Stellar evolution is the process by which a star changes over the course of time.

Stellar parallax

Stellar parallax is the apparent shift of position of any nearby star (or other object) against the background of distant objects.
