	Gacrux (Site not responding. Last check: 2007-10-22)
		"Gacrux" is a prime example of such a star, its name deriving strictly from its Greek letter name, Gamma Crucis, the third-brightest star in the constellation Crux, the Southern Cross.
		Tied with Shaula in Scorpius for third-place in the second magnitude rank (1.63), Gacrux is (with Shaula) the 24th brightest star in the sky.
		Gacrux, however, is a cool red class M (M 3.5) giant star, one that shines nicely in contrast to the other three, blue, stars of the Cross.

	Gacrux / Gamma Crucis 2?
		For a time, observers believed that Gacrux had a faint, bluish white (A3 V) binary companion lying within two minutes of arc that is still designated in the SIMBAD Astronomical Database and the Yale Bright Star Catalogue, 1991 5th Revised Edition as Gamma Crucis B (HR 4764 or HD 108925).
		Gacrux is a cool red giant star of spectral and luminosity type M3.5 III (but was once thought to be a "bright giant" of luminosity type II).
		Gacrux has been found to be variable by a few tenths of a magnitude.

		Gacrux (γ Cru / γ Crucis / Gamma Crucis) is the third brightest star in constellation Crux (the Southern Cross) and the one of the brightest stars in the nighttime sky.
		Since Gamma Crucis is at roughly −60° declination, it is only visible south of the Tropic of Cancer and therefore didn't receive an ancient traditional name; "Gacrux" is simply a combination of the "Ga" in Gamma plus Crux.
		Gamma Crucis is a binary star, 120 light years distant from Earth.

		Gacrux is a relatively bright star with a magnitude of 2.
		The reported distance may be erroneous; it's been calculated from the visual and absolute magnitudes.
		The names Becrux and Gacrux for Beta and Gamma Crucis have a similar modern origin.

	Gacrux (Gamma Crucis)
		At first, Gacrux looks double, with a faint, nearly seventh magnitude A-type companion about 2' away, but this is just a line-of-sight coincidence.
		Though usually taken to be single, the fact that Gacrux is a mild barium star hints that its surface may have been contaminated by the stellar wind from a companion that evolved first and is now a dim white dwarf.
		Certainly, Gacrux is variable, by a few tenths of a magnitude.

		The crowning star of the Southern Cross is Gacrux or Gamma Crucis, 88 light years (27 parsecs) from Earth.
		This is a red giant star, indicating that it is reaching the end of its stellar lifespan.
		It is a binary (that is, it has an less luminous and smaller companion star), and is also variable - its brightness changes over time.

		The name hadar comes from the Arabic word for "ground", while the name agena comes from Latin words for "the knee".
		Hadar is also useful as a guide star, making an imaginary line with Rigil Kentaurus that passes within a few degrees of Gacrux, in the constellation Crux.
		Using Gacrux, a navigator can draw a line with Acrux to effectively determine south.

		As its star, a red giant over a hundred times the size of Sol, is well into its final years, Gacrux, too, is a world in a state of decline, cooling as the warmth of its primary fades more and more with each passing century.
		Since that day, the people of Gacrux became known for their remarkable loyalty to the Commonwealth, and were among the few Skye worlds not opposed to Steiner rule during the region's rebellious years.
		This attitude made Gacrux one of the strongholds of a Lyran supremacist movement - formerly a veterans association - called the Brotherhood of Cincinnatus, a group that achieved infamy during the mid-thirty-first century for a string of domestic terrorist attacks.

		In the year around 2477 BC, the star Gacrux at the top of the Southern Cross constellation reached the altitude of 26d 18m at it's daily crossing of the meridian line as seen from Giza.
		In/around the 2477 BC period, it happens that the RA of Gacrux is 9h10.77m or rounded off 9h 11m and if the current software were able to fully account for the proper motion of the star, may in fact be 9h 11m.
		When examining the full sky chart again, at the daily meridian passing of Gacrux with a RA of ~9h11m, it is perhaps of significance that both the alpha (Diadem) and beta stars of Coma are in a straight line also along the meridian above Crux and Virgo and have essentially the same RA of 9h10-9h11m.

		Gacrux, however, is a cool red class M (M 3) giant star, one that shines nicely in contrast to the other three, blue, stars of the Cross.
		And a true giant it is. From its rather nearby distance of 88 light years, and its temperature of 3,040 Kelvin (from which we can estimate the amount of invisible infrared radiation shining from its cool surface), we calculate a luminosity of 1500 Suns, which leads to a radius 113 solar.
		Perhaps one day it will appear to us as a full-blown pulsating variable like Mira in Cetus.

		APOD: 2004 July 8 - Southern Cross Star Colors: "In this case, the subject is one of the most famous constellations in the night sky, Crux, the Southern Cross.
		Actually a binary star system, Acrux is the alpha star of the compact Southern Cross and lies along a line pointing from Gacrux to the South Celestial Pole, off the lower right edge of the picture.
		Adding a separate short exposure to the end of the step-focussed trails to better show the positions of the stars themselves, astronomer Stefan Seip recorded this remarkable image last May in the dark night skies above Namibia.

		It is surrounded on three sides by the constellation Centaurus while to the south lies the Fly (Musca).
		With the lack of a significant pole star in the southern sky (Sigma Octantis is closest to the pole, but is so faint as to be useless for the purpose), two of the stars of Crux (Alpha and Gamma, Acrux and Gacrux respectively) are commonly used to mark south.
		Following the line defined by the two stars for approximately 4.5 times the distance between them leads to a point close to the Southern Celestial Pole.

		Though they use different names for the stars, they, in fact, use the rising and setting azimuth of the star Gacrux, as displayed in the table.
		This configuration is visible from latitudes up to 26N, after which it becomes too low to view the bottom of the Cross.
		As the Southern Cross continues to the west, and forms an angle of 45 degrees from the west, as shown in Figure 3, an azimuth of 205 degrees lies directly beneath Gacrux.

		Though Delta Crucis does not appear to have a proper name, its three brighter companions do: they are known as Acrux, Becrux and Gacrux, respectively.
		These are, without doubt, the three least inspired star names in the entire sky.
