FP Velorum Facts

FP Velorum's Alternative Names

HIP48499 is the reference name for the star in the Hipparcos Star Catalogue.

FP Velorum has alternative name(s) :- , FP Vel.

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

Location of FP Velorum

The location of the Carbon 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 FP Velorum, the location is 09h 53m 25.96 and -52° 30` 33.8 .

Physical Properties (Colour, Temperature) of FP Velorum

FP Velorum Colour and Temperature

FP Velorum has a spectral type of C. This means the star is a carbon red Carbon star. The star has a B-V Colour Index of 2.1 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 1,181 Kelvin.

FP Velorum Apparent and Absolute Magnitudes

FP Velorum has an apparent magnitude of 10.51 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 FP Velorum

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -1.70 which gave the calculated distance to FP Velorum as 0 light years away from Earth or 0 parsecs. If you want that in miles, it is 0.

Variable Type of FP Velorum

The star is a pulsating Slow Irregular 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. FP Velorum brightness ranges from a magnitude of 10.717 to a magnitude of 10.464 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.2 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.
