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.

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.

Bortle scale
The Bortle scale is a nine-level numeric scale that measures the night sky's brightness of a particular location.

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

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.

Epoch (astronomy)
In astronomy, an epoch is a moment in time used as a reference point for some time-varying astronomical quantity, such as the celestial coordinates or elliptical orbital elements of a celestial body, because these are subject to perturbations and vary with time.

International Celestial Reference System
The International Celestial Reference System (ICRS) is the current standard celestial reference system adopted by the International Astronomical Union (IAU).

Latinisation of names
Latinisation or Latinization is the practice of rendering a non-Latin name (or word) in a Latin style.

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.

Photometry (astronomy)
Photometry is a technique of astronomy concerned with measuring the flux, or intensity of an astronomical object's electromagnetic radiation.

Sextans
Sextans is a minor equatorial constellation which was introduced in 1687 by Johannes Hevelius.

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

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.
New!!: Beta Sextantis and Stellar parallax · See more »
Stellar rotation
Stellar rotation is the angular motion of a star about its axis.
New!!: Beta Sextantis and Stellar rotation · See more »
Subgiant
A subgiant is a star that is brighter than a normal main-sequence star of the same spectral class, but not as bright as true giant stars.
New!!: Beta Sextantis and Subgiant · See more »
Variable star
A variable star is a star whose brightness as seen from Earth (its apparent magnitude) fluctuates.
