Algol variable
Algol variables or Algol-type binaries are a class of eclipsing binary stars that are similar to the prototype member of this class, β Persei (Beta Persei, Algol). W Crucis and Algol variable are Algol variables.
See W Crucis and Algol variable
Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.
See W Crucis and Apparent magnitude
Astronomy & Astrophysics
Astronomy & Astrophysics (A&A) is a monthly peer-reviewed scientific journal covering theoretical, observational, and instrumental astronomy and astrophysics.
See W Crucis and Astronomy & Astrophysics
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.
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 W Crucis and Constellation
Crux
Crux is a constellation of the southern sky that is centred on four bright stars in a cross-shaped asterism commonly known as the Southern Cross.
Hipparcos
Hipparcos was a scientific satellite of the European Space Agency (ESA), launched in 1989 and operated until 1993.
International Astronomical Union
The International Astronomical Union (IAU; Union astronomique internationale, UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation.
See W Crucis and International Astronomical Union
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.
Main sequence
In astronomy, the main sequence is a classification of stars which appear on plots of stellar color versus brightness as a continuous and distinctive band.
See W Crucis and Main sequence
O'Connell effect
The O'Connell effect is an asymmetry in the photometric light curve of certain close eclipsing binary stars.
See W Crucis and O'Connell effect
Roche lobe
In astronomy, the Roche lobe is the region around a star in a binary system within which orbiting material is gravitationally bound to that star.
Spectral line
A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum.
See W Crucis and Spectral line
Supergiant
Supergiants are among the most massive and most luminous stars.
Yellow supergiant
A yellow supergiant (YSG) is a star, generally of spectral type F or G, having a supergiant luminosity class (e.g. Ia or Ib). W Crucis and yellow supergiant are g-type supergiants.
See W Crucis and Yellow supergiant
