As a result, its shape has been distorted into an oblate spheroid and the star’s diameter at the equator is 56% greater than its diameter at the poles. With an apparent magnitude of 0.9, it is one of the brightest astronomical objects in the sky.The Large Magellanic Cloud forms a pair with the Small Magellanic Cloud (SMC), another bright Milky Way satellite. Achernar, a hot class B (B3) dwarf, is the hottest of the top nine, rather handily beating out Rigel in Orion. This is common among rapidly rotating stars. Hoewel de bijbehorende ster kleiner is … 0.40 – 0.46), Cursa (Beta Eri, mag. Achernar is the only first-magnitude star not mentioned in Ptolemy’s Achernar remained unknown in the northern hemisphere until the age of discovery. 2.796), Acamar (Theta At the pole, the temperature may be above 20,000 K, while the equator is at or below 10,000 K. The average temperature of the star is about 15,000 K. The high polar temperatures are generating a fast polar wind that is ejecting matter from the star, creating a polar envelope of hot gas and plasma. It is circumpolar (it never sets) for observers south of latitude 33°S and can be seen throughout the year. The first star catalogue to include the star on the map of Eridanus is Johann Bayer’s Achernar is the brighter of the two stars in the constellation Eridanus selected for navigation. Achernar’s poles are inclined 65° to our line of sight. Its estimated luminosity is 3,150 times that of the Sun. Because they have a higher surface gravity, the poles also have a higher temperature and brightness. It lies in the same region in sky as the somewhat fainter For observers south of latitude 33°N, Achernar is easy to find, both because it is very bright and because it lies in the same area of the sky as two bright galaxies, the Large and Small Magellanic Clouds.Located in the constellations Dorado and Mensa, the Large Magellanic Cloud (LMC) is one of the closest galaxies to Earth and the fourth largest member of the Local Group, after the Andromeda Galaxy (M31), the Milky Way and the Triangulum Galaxy (M33).
The other one is Acamar, Theta Eridani. Notable uses include M. A. R. Barker’s The name Achernar (pronunciation: /ˈeɪkərnɑːr/) comes from the Arabic phrase The name was officially approved for Alpha Eridani A by the International Astronomical Union’s (IAU) Working Group on Star Names (WGSN) on June 30, 2016. Achernar B was given the spectral type A0V-A3V and its estimated mass is about twice that of the Sun. Circumstellar disks are common in Be stars, hot stars with hydrogen and neutral helium in their optical spectra, many of which have circumstellar material. The 58 navigational stars have special status in the field of celestial navigation because they are among the brightest and recognizable stars in the sky.Even if most northern observers will never see Achernar, many know the star from one of the many works of fiction in which it has been used or mentioned. Achernar Achernar (alpha Eridani) is de helderste ster in het sterrenbeeld Eridanus (Rivier Eridanus) en een van de helderste aan de hemel. 47 Tucanae, the second brightest globular cluster in the sky (after Omega Centauri) can be seen next to the Small Magellanic Cloud.Achernar can be used to find the south celestial pole, which lies roughly halfway between the star and the Southern Cross, formed by the bright stars The pole can also be located by drawing an imaginary equilateral triangle with Achernar and Sigma Octantis (Polaris Australis), the star that marks true south, is the closest visible star to the south celestial pole, but as it is not very bright (at mag. Around 3400 BCE, its declination was 82°40’, placing it within 7.5 degrees of the south celestial pole. De ster is een blauwe superreus en draait zo snel om haar as dat de diameter om de evenaar meer dan 50% groter is dan die om de polen gemeten. To observers south of latitude 20°N, the galaxy appears as a faint cloud.
