Location of S Volantis

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 S Volantis, the location is 07h 29m 45.57 and -73° 22` 44.1 .

Physical Properties of S Volantis

S Volantis Temperature and Colour

Based on the star's spectral type of M4e , S Volantis's colour and type is red variable star. The star has a B-V Colour Index of 1.5 which means the star's temperature is about 4,014 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu.

S Volantis Apparent and Absolute Magnitudes

S Volantis has an apparent magnitude of 10.37 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 S Volantis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -0.23000 which gave the calculated distance to S Volantis as -14181.01 light years away from Earth or -4347.83 parsecs. If you want that in miles, it is about -83,364,845,203,370,505.25, based on 1 Ly = 5,878,625,373,183.61 miles.

Variable Type of S Volantis

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. S Volantis brightness ranges from a magnitude of 12.432 to a magnitude of 8.761 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 393.8 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.
