Minelauva, Delta Virginis, 43 Virginis, HD112300, HIP63090, HR4910

Minelauva (Delta Virginis) is a red pulsating star that can be located in the constellation of Virgo. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it.

Delta Virginis is the Bayer Classification for the star. The Id of the star in the Yale Bright Star Catalogue is HR4910. HIP63090 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD112300. The Id of the star in the Gould Star Catalogue is 95. Stars in the southern hemisphere are more likely to have a Gould Id than the northern hemisphere. For example, there are no Gould classified stars in Ursa Major.

Minelauva has alternative name(s), Auva , NSV 06026.

Location of Minelauva

The location of the star in the galaxy 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 star is compared to the celestial equator and is expressed in degrees. For Minelauva, the location is 12h 55m 36.48 and +03d 23` 51.4 .

Proper Motion of Minelauva

All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. In the case of a star, its the galactic centre. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Proper Motion details the movements of these stars and are measured in milliarcseconds. The star is moving -52.83 ± 0.14 miliarcseconds/year towards the north and -469.99 ± 0.22 miliarcseconds/year east if we saw them in the horizon. The Radial Velocity, that is the speed at which the star is moving away/towards us is -18.87000 km/s with an error of about 0.21 km/s .

Minelauva Luminosity

Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. The figure of 10.0000000 that I have given is based on the Spectral Types page that I have found on the Internet. You might find a different figure, one that may have been calculated rather than generalised that I have done. The figure is always the amount times the luminosity of the Sun. It is an imprecise figure because of a number of factors including but not limited to whether the star is a variable star and distance.

Physical Properties (Colour, Temperature, Radius) of Minelauva

Minelauva has a spectral type of M3III. This means the star is a red star. The star is 7386.00000000 Parsecs from the Galactic Centre or terms of Light Years is 24090.4245878400000000s. The star has a B-V Colour Index of 1.57 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 3,850 Kelvin.

Minelauva Radius has been calculated as being 27.29 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 18,987,682.77.km. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 26.79. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures. The star's Iron Abundance is -0.06 with an error value of 9.99 Fe/H with the Sun has a value of 1 to put it into context.

Minelauva Apparent and Absolute Magnitudes

Minelauva has an apparent magnitude of 3.39 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. If you used the 1997 Parallax value, you would get an absolute magnitude of -0.57 If you used the 2007 Parallax value, you would get an absolute magnitude of -0.53. 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 Minelauva

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 16.11 which gave the calculated distance to Minelauva as 202.46 light years away from Earth or 62.07 parsecs. It would take a spaceship travelling at the speed of light, 202.46 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

In 2007, Hipparcos data was revised with a new parallax of 16.44 which put Minelauva at a distance of 198.40 light years or 60.83 parsecs. It should not be taken as though the star is moving closer or further away from us. It is purely that the distance was recalculated.

The star's Galacto-Centric Distance is 7,386.00 Parsecs or 24,090.42 Light Years. The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*.

Variable Type of Minelauva

The star is a pulsating Semi-Regular Star which are giants or supergiants of intermediate and late spectral 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. Minelauva brightness ranges from a magnitude of 3.483 to a magnitude of 3.414 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.1 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.

Multi-Star System

The star has been identified as being a multi-star system, one in which there is at least one star in close orbit to another star or two or more stars orbiting a central point. The stars may be of equal mass, unequal mass where one star is stronger than the other or be in groups orbiting a central point which doesn't necessarily have to be a star. More information can be found on my dedicated multiple star systems page. The source of the info is Simbad. The file is dated 2000 so any differences between this and any other source will be down to the actual source from where the information came from.
