BE Centauri

BE Centauri Facts

BE Centauri's Alternative Names

HIP73533 is the reference name for the star in the Hipparcos Star Catalogue.

BE Centauri has alternative name(s) :- BE Cen, BE Cen.

More details on objects' alternative names can be found at Star Names .

Location of BE Centauri

The location of the variable star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For BE Centauri, the location is 15h 01m 46.23 and -30° 14` 40.3 .

Physical Properties (Colour, Temperature) of BE Centauri

BE Centauri has a spectral type of Me. This means the star is a red variable star. The star has a B-V Colour Index of 1.5 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 4,014 Kelvin.

BE Centauri Apparent and Absolute Magnitudes

BE Centauri has an apparent magnitude of 12.39 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.

Variable Type of BE Centauri

The star is a pulsating Omicron Ceti variable type which means that its size changes over time. The Variable Type is usually named after the first star of that type to be spotted. BE Centauri brightness ranges from a magnitude of 12.828 to a magnitude of 9.666 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 198.8 days (variability).

Source of Information

The source of the information if it has a Hip I.D. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Hipparcos was a E.S.A. satellite operation launched in 1989 for four years. The items in red are values that I've calculated so they could well be wrong. Information regarding Metallicity and/or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
