WY Antliae

Primary Facts on WY Antliae

WY Antliae's Alternative Names

HIP50289 is the reference name for the star in the Hipparcos Star Catalogue.

WY Antliae has alternative name(s) :- WY Ant, WY Ant.

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

Location of WY Antliae

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 WY Antliae, the location is 10h 16m 04.92 and -29° 43` 42.0 .

Physical Properties (Colour, Temperature) of WY Antliae

WY Antliae has a spectral type of A8.7. This means the star is a blue variable star. The star has a B-V Colour Index of 0.27 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 6,943 Kelvin. The star's Iron Abundance is -1.51 with an error value of 9.99 Fe/H with the Sun has a value of 1 to put it into context.

WY Antliae Apparent and Absolute Magnitudes

WY Antliae has an apparent magnitude of 10.95 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of 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.

Distance to WY Antliae

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.00 which gave the calculated distance to WY Antliae as -1 light years away from Earth or -1 parsecs. It would take a spaceship travelling at the speed of light, -1 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

Variable Type of WY Antliae

The star is a pulsating RR Lyrae type with a 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. WY Antliae brightness ranges from a magnitude of 11.353 to a magnitude of 10.401 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.6 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.
