Aldebaran, designated Alpha Tauri Tauri, abbreviated Alpha Tau, Tau, is an orange giant star located about 6. Sun in the zodiacconstellation of Taurus. It is the brightest star in its constellation and usually the fourteenth brightest star in the nighttime sky, though it varies slowly in brightness between magnitude 0. It is likely that Aldebaran hosts a planet several times the size of Jupiter. The planetary exploration probe Pioneer 1. NomenclatureeditAlpha Tauri is the stars Bayer designation. The name Aldebaran is Arabic al dabarn and means the Follower, presumably because it rises near and soon after the Pleiades. In 2. 01. 6, the International Astronomical Union organized a Working Group on Star Names WGSN1. The WGSNs first bulletin of July 2. WGSN which included Aldebaran for this star. It is now so entered in the IAU Catalog of Star Names. Names in other languageseditIn Persia it was known as Tascheter. In Brazilian Portuguese it was known as Aquele Que Segue or Olho do Tourocitation neededThe Romans called it Palilicium. In the Middle Ages it was sometimes called Cor Tauri the Heart of the BullTauruscitation needed. John Gower refers to it as Aldeboran. In Chinese it is known as Bxiw, the Fifth Star of the Net. In Hindu astronomy it is identified as the lunar mansion Rohini the red one and as one of the twenty seven daughters of Daksha and the wife of the god Chandra moon. MythologyeditThis easily seen and striking star in its suggestive asterism is a popular subject for ancient and modern myths. Mexican culture For the Seris of northwestern Mexico, this star provides light for the seven women giving birth Pleiades. It has three names Hant Caalajc Ippj, Queeto, and Azoj Yeen oo Caap star that goes ahead. The lunar month corresponding to October is called Queeto yaao Aldebarans path. Aboriginal culture in the Clarence River of northeastern New South Wales, this star is the Ancestor Karambal, who stole another mans wife. The womans husband tracked him down and burned the tree in which he was hiding. It is believed that he rose to the sky as smoke and became the star Aldebaran. Observation historyeditOn 1. March AD 5. 09, a lunar occultation of Aldebaran was observed in Athens, Greece. English astronomer Edmund Halley studied the timing of this event, and in 1. Aldebaran must have changed position since that time, moving several minutes of arc further to the north. This, as well as observations of the changing positions of stars Sirius and Arcturus, led to the discovery of proper motion. Based on present day observations, the position of Aldebaran has shifted 7 in the last 2. Moon. 2. 42. 5 Note that 5,0. Aldebaran. citation neededEnglish astronomer William Herschel discovered a faint companion to Aldebaran in 1. This star was shown to be itself a close double star by S. W. Burnham in 1. 88. Follow on measurements of proper motion showed that Herschels companion was diverging from Aldebaran, and hence they were not physically connected. However, the companion discovered by Burnham had almost exactly the same proper motion as Aldebaran, suggesting that the two formed a wide binary star system. Working at his private observatory in Tulse Hill, England, in 1. William Huggins performed the first studies of the spectrum of Aldebaran, where he was able to identify the lines of nine elements, including iron, sodium, calcium, and magnesium. In 1. 88. 6, Edward C. Pickering at the Harvard College Observatory used a photographic plate to capture fifty absorption lines in the spectrum of Aldebaran. This became part of the Draper Catalogue, published in 1. By 1. 88. 7, the photographic technique had improved to the point that it was possible to measure a stars radial velocity from the amount of Doppler shift in the spectrum. By this means, the recession velocity of Aldebaran was estimated as 3. Potsdam Observatory by Hermann C. Vogel and his assistant Julius Scheiner. Aldebaran was observed using an interferometer attached to the Hooker Telescope at the Mount Wilson Observatory in 1. Physical propertiesedit. Size comparison between Aldebaran and the Sun. Aldebaran is classified as a type K5 III star, which indicates it is an orange hued giant star that has evolved off the main sequence band of the HertzsprungRussell diagram after exhausting the hydrogen at its core. The collapse of the centre of the star into a degenerate helium core has ignited a shell of hydrogen outside the core and Aldebaran is now a red giant. This has caused it to expand to 4. Sun,1. 13. 1 equivalent to approximately 6. Measurements by the Hipparcos satellite and other sources put Aldebaran around 6. Stellar models predict it only has about 5.

It varies by about 0. With a near infrared. J bandmagnitude of 2. Betelgeuse 2. 9, R Doradus 2. Arcturus 2. 2 are brighter. The photosphere shows abundances of carbon, oxygen, and nitrogen that suggest the giant has gone through its first dredge up stagea normal step in the evolution of a star into a red giant during which material from deep within the star is brought up to the surface by convection. With its slow rotation, Aldebaran lacks a dynamo needed to generate a corona and hence is not a source of hard X ray emission. However, small scale magnetic fields may still be present in the lower atmosphere, resulting from convection turbulence near the surface. The measured strength of the magnetic field on Aldebaran is 0. G. 3. 2 Any resulting soft X ray emissions from this region may be attenuated by the chromosphere, although ultraviolet emission has been detected in the spectrum. The star is currently losing mass at a rate of 11. M yr1 with a velocity of 3. This stellar wind may be generated by the weak magnetic fields in the lower atmosphere. Beyond the chromosphere of Aldebaran is an extended molecular outer atmosphere MOLsphere where the temperature is cool enough for molecules of gas to form. This region lies between 1. K. The spectrum reveals lines of carbon monoxide, water, and titanium oxide. Past this radius, the modest outflow of the stellar wind itself declines in temperature to about 7,5. K at a distance of 1 Astronomical Unit AUthe distance of the Earth from the Sun. The wind continues to expand until it reaches the termination shock boundary with the hot, ionized interstellar medium that dominates the Local Bubble, forming a roughly spherical astrosphere with a radius of around 1,0. AU, centered on Aldebaran. Visibilityedit. Occultation of Aldebaran by the Moon. Aldebaran is one of the easiest stars to find in the night sky, partly due to its brightness and partly due to its spatial relation to one of the more noticeable asterisms in the sky. If one follows the three stars of Orions belt from left to right in the Northern Hemisphere or right to left in the Southern, the first bright star found by continuing that line is Aldebaran.
