HIP 25527, HD36007

HIP 25527 is a blue to white main sequence dwarf star that can be located in the constellation of Columba. The description is based on the spectral class. HIP 25527 is not part of the constellation but is within the borders of the constellation.

The star can not be seen by the naked eye, you need a telescope to see it. The star has an estimated age of 2.20 Billion of Years but could be as young as 2.00 to 2.40 according to Hipparcos.

HIP 25527's Alternative Names

HIP25527 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD36007.

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

Location of HIP 25527

The location of the 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 star is compared to the celestial equator and is expressed in degrees. For HIP 25527, the location is 05h 27m 30.94 and -27° 16` 09.0 .

Radial Velocity and Proper Motion of HIP 25527

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 -12.75 ± 0.82 miliarcseconds/year towards the north and -5.65 ± 1.05 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 the Sun is 27.50 km/s with an error of about 0.40 km/s . When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever.

Physical Properties (Colour, Temperature, Age) of HIP 25527

HIP 25527 has a spectral type of F3V. This means the star is a blue to white main sequence dwarf star. The star has a B-V Colour Index of 0.44 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 6,545 Kelvin.

HIP 25527 Radius has been calculated as being 3.14 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 2,185,499.24.km. If you need the diameter of the star, you just need to multiple the radius by 2. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 2.51. 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 -0.16 with an error value of 0.08 Fe/H with the Sun has a value of 1 to put it into context.

The stars age according to Hipparcos data files put the star at an age of about 2.20 Billion years old but could be between 2.00 and 2.40 Billion years old. In comparison, the Sun's age is about 4.6 Billion Years Old.

HIP 25527 Apparent and Absolute Magnitudes

HIP 25527 has an apparent magnitude of 8.87 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 1.82 If you used the 2007 Parallax value, you would get an absolute magnitude of 2.31. 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 HIP 25527

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 3.89 which gave the calculated distance to HIP 25527 as 838.47 light years away from Earth or 257.07 parsecs. It would take a spaceship travelling at the speed of light, 838.47 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 4.87 which put HIP 25527 at a distance of 669.74 light years or 205.34 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.

Using the 2007 distance, the star is roughly 42,354,120.19 Astronomical Units from the Earth/Sun give or take a few. An Astronomical Unit is the distance between Earth and the Sun. The number of A.U. is the number of times that the star is from the Earth compared to the Sun.

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.
