	Achernar (Alpha Eridani)
		Achernar is extremely flattened by its rapid spin.
		Achernar's high spin velocity of at least 250 km/s has led to it becoming a Be star.
		Achernar also shows small, regular light variations of a type that make it a Lambda Eridani star.

	USS Achernar (AKA-53) - Wikipedia, the free encyclopedia
		Achernar stopped at Eniwetok on 26 February, Kossol Roads on 4 March, and anchored in San Pedro Bay, Philippine Islands, from 15 March to 20 March, before arriving off Okinawa on 1 April to support the seizure of that key island.
		Achernar got underway again on 16 January 1946 and resumed operations between the west coast and various ports in the Far East and the Pacific.
		Achernar held shakedown in the Caribbean and spent the remainder of her career conducting various training exercises in the Virginia capes operating area.

	Achernar - Wikipedia, the free encyclopedia
		Achernar (α Eri / α Eridani / Alpha Eridani) is the brightest star in the constellation Eridanus and the ninth brightest star in the nighttime sky.
		Achernar is a bright supergiant star visible in the southern part of the night sky.
		Achernar spins so rapidly that its equatorial diameter is more than 50% greater than its polar diameter.

	Achernar / Alpha Eridani
		Achernar is a blue-white main sequence star of spectral and luminosity type B3 Vpe (Hiltner et al, 1969), that previously had been classed as bright as a subgiant.
		Achernar is also a member of a peculiar class of Lambda Eridani-type stars that show small but very regular periodic light variations (with a period of 1.26 days) that may be caused by actual complex pulsations or by rotation and dark "starspots" (Balona et al, 1987).
		Although Achernar is a massive star, it is still young enough to be fusing hydrogen into helium in its core and may be small enough to evolve off the sequence as a massive white dwarf like Sirius B.

		Achernar, however, is nowhere nearly as well known to northerners, as it is a deep southern star, visible only to those who live below 32 degrees north latitude, and easily noted only from the tropics and south.
		The name, from an Arabic phrase, means "the end of the river," as appropriate for the star that ends the southerly flow of Eridanus, the River, the celestial depiction of River Ocean, a meandering flow of mostly faint stars that originates with Cursa, on which Orion rests his foot.
		Achernar is also a member of a peculiar class of "Lambda Eridani" stars that show tiny but very regular periodic light variations that may be caused by actual complex pulsations or by rotation and dark "starspots." No one really knows.

	Flattest star ever seen
		Achernar is a star of the hot B-type, with a mass of 6 times that of the Sun.
		The angular size of Achernar''s elliptical profile as indicated in PR Photo 15b/03 is 0.00253 ± 0.00006 arcsec (major axis) and 0.00162 ± 0.00001 arcsec (minor axis) [4], respectively.
		The indicated ratio between the equatorial and polar radii of Achernar constitutes an unprecedented challenge for theoretical astrophysics, in particular concerning mass loss from the surface enhanced by the rapid rotation (the centrifugal effect) and also the distribution of internal angular momentum (the rotation velocity at different depths).

	Achernar Bcast Co v. FCC
		Achernar's primary contention is that the Commission failed to "consider all aspects of the problem," as required by rule 73.1030(a).
		Achernar maintains that the Commission's rigid protection of the zone defeats the rule's stated intent to provide a means of protecting NRAO's observations without impeding the development of broadcast services to the Quiet Zone since the denial of a license that would not damage NRAO directly impedes such development.
		Achernar claims that the FCC based its rejection of a sharing agreement on specific terms of the proposed agreement rather than considering the concept and allowing Achernar to remedy any specific objections by creating a different agreement.

		The apparent profile of Achernar (PR Photo 15b/03), based on about 20,000 VLTI interferograms (in the K-band at wavelength 2.2 =B5m) with a total integration time of over 20 hours, indicates a surprisingly high axial ratio of 1.56 =B1 0.05 [3].

		However, the astronomers monitored the star's emission for signs of such an envelope (an "equatorial disk") during the VLTI observations; there were no signs and they were therefore able to establish narrow limits on the possible influence of this effect on the apparent flatness of the star.

		Although not necessarily a religion of shamanism, the faithful of Achernar hold great respect for those who commune with spirits and the power to be found in drawing from the spirit world.
		While they recognize the inherent power of necromancy, Achernar's priests view most necromancers as infidels who do not show proper homage to their Lord, and consider it an affront when the dead are desecrated, disturbing their final rest.
		The Church of Achernar is very loosely organized, usually only drawing together to face a threat against the faith as a whole.

	SPACE.com -- The 10 Brightest Stars
		Achernar is derived from the Arabic phrase meaning "the end of the river," an appropriate name for a star that marks the southernmost flow of the constellation Eridanus, the River.
		However, Achernar is generally listed as the ninth brightest star in the sky because Betelgeuse is a variable whose magnitude can drop to less than 1.2, as was the case in 1927 and 1941.
		For Northern Hemisphere observers, Achernar rises in the southeast during the winter months and is visible only from latitudes south of 32 degrees north; those further north only see a portion of the constellation.

	[7.04] Models for the Rapidly Rotating Be Star Achernar (Site not responding. Last check: 2007-10-16)
		We present models for the Be star Achernar (\alpha Eridani), which recent interferometric observations have shown has a photospheric shape that is significantly distorted by the effects of rotation.
		For models with masses like those of main sequence stars of mid to early B spectral type, it is possible to reproduce Achernar's inferred equatorial and polar dimensions through a combination of rotational flattening/distension and suitable inclination of the rotation axis.
		However, while matching Achernar's apparent shape, these models are discrepant in other respects, being (on average) cooler and more rapidly rotating than observations indicate.
