Paikauhale is the Hawaiian name for Tau Scorpii. (2007) computed a more accurate estimate of 568+75 −59 ligh… Paikauhale visual magnitude is 2.82. For Paikauhale, the location is 16h 35m 52.96 and -28° 12` 57.5 . This star is now referred to as Paikauhale and over time will no longer be associated with the name Al Niyat.

[3] It is radiating about 20,400[7] times the Sun's luminosity from its outer envelope at an effective temperature of 31,440 K.[9] This gives it the blue-white hue characteristic of B-type stars. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. 2 kilometers per second. 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. [17][18] In the Hawaiian dictionary by Pukuʻi & Elbert (1986), the word paikauhale [ˈpəiˈkəuˈhale] is defined as to go gadding about from house to house. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever. Compared to the Sun, Tau Scorpii is a massive OB star with 15 times the Sun's mass and more than six times the radius of the Sun. Scorpius-Centaurus OB association, Greenwich, United Kingdom [change] are

This star is a proper motion member of the Upper Scorpius subgroup of the All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. Distance, of course.

Mach 1 is the speed of sound, Mach 2 is twice the speed of sound. If you need the diameter of the star, you just need to multiple the radius by 2. Tau Scorpii (τ Sco, τ Scorpii), formally known as Paikauhale /ˌpaɪkaʊˈhɑːleɪ/, is a star in the southern zodiac constellation of Scorpius. Based on the star's spectral type of B0V , Paikauhale's colour and type is blue main sequence star. [5][7] Latitude: 51° 28’ 47” N Tau Scorpii is rotating relatively slo…

[14] The hard component of the X-ray spectrum from τ Sco as studied with XMM-Newton supports the presence of in-falling clumps of plasma in τ Sco.[14]. Longitude: 0° 00’ 00” E The value comes from the Hipparcos Extended Catalog.

Exoplanets. The star is moving -22.83 ± 0.40 milliarcseconds/year towards the north and -9.89 ± 0.53 milliarcseconds/year east if we saw them in the horizon. H-R diagram showing the position of Paikauhale. Paikauhale, also designated as τ Scorpii (tau Scorpii), is a hypergiant star in the constellation of Scorpius. the Hertzsprung–Russell diagram. The system consists of the red supergiant Alpha Scorpii A, formally named Antares, and a fainter blue-white main sequence star designated Alpha Scorpii B. Antares has an apparent magnitude that varies between 0.6 and 1.6, while the companion is considerably fainter at magnitude 5.5. Shaula, Lambda Scorpii (λ Sco), is a triple star system located at a distance of about 570 light years from Earth in the direction of the constellation Scorpius.With an apparent magnitude of 1.62, it is the second brightest star in Scorpius, fainter only than the red supergiant Antares.. Shaula is the 24th brightest star in …
situated south of the celestial equator, as such, it is more easily visible from the southern emisphere. has done some calculations as to how long it will take going at differing speeds. the credits section) taken in the red channel. An Astronomical Unit is the distance between Earth and the Sun. Over the energy range 0.8–1.2 keV, its X-ray luminosity is Lx = 1.8 × 1031 erg s−1 with a large Lx to Lbol of log Lx/Lbol = –6.53 from ASCA measurements. The location of the main sequence 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. [22] Consequently, the Chinese name for τ Scorpii itself is 心宿三 (Xīn Xiù sān), "the Third Star of Heart". 429.51 light years from the Sun and it is As such, the fossil-field theory was more likely. Kent, 1993, "Treasury of Hawaiian Words in One Hundred and One Categories", p.367), paikauhale is defined as Vagabond owning no home; house-to-house wanderer. Thank you!
Al Niyat is the upper of the two stars that flank Antares, the bright star in the heart of Scorpius (and whose Arabic name means just … Attribution. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Paikauhale estimated radius has been calculated as being 3.89 times bigger than the Sun. Simplified finder chart for Paikauhale - τ Scorpii (tau Scorpii). The New Horizons space probe is the fastest probe that we've sent into space at the time of writing.

The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Celestial coordinates for the J2000 equinox as well as galactic coordinates of Paikauhale are provided in the following table: The simplified sky map below shows the position of Paikauhale in the sky: Location: Greenwich, United Kingdom [change] Paikauhale visual magnitude is 2.82. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days). The figure is derived at by using the formula from SDSS rather than peer reviewed papers. If you want that in miles, it is about 2,526,221,681,618,192.73, based on 1 Ly = 5,878,625,373,183.61 miles. Double stars are common. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet. The name Alniyat was given to Sigma Scorpii. Proper Motion details the movements of these stars and are measured in milliarcseconds. It is purely that the distance was recalculated. Paikauhale is distant is the number of times that the star is from the Earth compared to the Sun. In the case of a star, its the galactic centre. The indigenous Boorong people of northwestern Victoria saw this star (together with σ Sco) as wives of Djuit (Antares). This system has a combined apparent visual magnitude of +2.88, making it one of the brighter members of the constellation. Based upon parallax measurements made during the Hipparcos mission, the distance to Sigma Scorpii is roughly 696 light-years (214 parsecs). U.G. The apparent visual magnitude of Tau Scorpii is +2.8,[2] while parallax measurements yield a distance estimate of roughly 470 light-years (150 parsecs) from Earth. Thanks to its high brightness, Paikauhale is clearly visible when observed from locations with dark skyes,

The area of sky represented in the image is 0.5x0.5 degrees (30x30 arcmins). The red arrow shows the motion of Paikauhale during the next. You can decline to give a name which if that is the case, the comment will be attributed to a random star. Timezone: Europe/London. [21], In Chinese, 心宿 (Xīn Xiù), meaning Heart, refers to an asterism consisting of τ Scorpii, σ Scorpii and Antares.

[15] Tau Scorpii is rotating relatively slowly with a period of 41 days. [20] Scientists had previously determined that Tau Scorpii is a blue straggler, which are produced by the merging of two stars. -0.008 arcsec per year in Right Ascension and -0.022 arcsec per year in Declination and the associated displacement The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it. [1], Compared to the Sun, Tau Scorpii is a massive OB star with 15[6] times the Sun's mass and more than six times the radius of the Sun. In another Hawaiian dictionary (H.W. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. [13] As yet there is no evidence of a companion in orbit around τ Sco. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between between 10,000 and 25,000K based on the notes from Harvard University. As yet there is no evidence of a companion in orbit around τ Sco. The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 1.70000 km/s with an error of about 0.90 km/s .

Zdanlivá hviezdna veľkos ť Tau Scorpii je +2,8, zatiaľ čo merania paralaxy poskytujú odhad vzdialenosti približne 470 svetelných rokov od Zeme. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 7.59000 which gave the calculated distance to Paikauhale as 429.73 light years away from Earth or 131.75 parsecs. Information regarding Metallicity and/or Mass is from the E.U. It is radiating about 20,400 times the Sun's luminosity from its outer envelope at an effective temperature of 31,440 K. This gives it the blue-white hue characteristic of B-type stars.

North et al. Observations with the ROSAT space telescope showed it has a higher energy (harder) X-ray spectrum than is usual for B0 V stars. AL NIYAT (Sigma Scorpii). Paikauhale, also designated as τ Scorpii (tau Scorpii), In 2016, the IAU organized a Working Group on Star Names (WGSN)[19] to catalog and standardize proper names for stars.

the nearest such co-moving association of massive stars to the Sun. [10], The spectrum of this star shows triply ionized oxygen (O IV) that is being generated by X-rays and the Auger ionization effect. Based on the spectral type (B0V) of the star, the star's colour is blue . Your guide to the Solar System and the night sky. All messages will be reviewed before being displayed. The items in red are values that I've calculated so they could well be wrong. [14] It is a magnetic star whose surface magnetic field was mapped by means of Zeeman–Doppler imaging. If the R.A. is positive then its eastwards. ROSAT measurements showed a log Lx/Lbol ≃ –5.93 for the range 0.1–2.4 keV.
