The apparent magnitude of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth.
Auriga is one of the 88 modern constellations; it was among the 48 constellations listed by the 2nd-century astronomer Ptolemy.
A binary star is a star system consisting of two stars orbiting around their common barycenter.
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.
Gamma Doradus variables are variable stars which display variations in luminosity due to non-radial pulsations of their surface.
Hipparcos was a scientific satellite of the European Space Agency (ESA), launched in 1989 and operated until 1993.
A red dwarf (or M dwarf) is a small and relatively cool star on the main sequence, of M spectral type.
Sky & Telescope (S&T) is a monthly American magazine covering all aspects of amateur astronomy, including the following.
A star is type of astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.
Stellar parallax is the apparent shift of position of any nearby star (or other object) against the background of distant objects.
Variable stars are designated using a variation on the Bayer designation format of an identifying label (as described below) combined with the Latin genitive of the name of the constellation in which the star lies.
