[22] The discovery was made by analysing variations in the star's radial velocity (measured by observing the Doppler shift of the star's spectral lines) as a result of being pulled around by the planet's gravity. In the equatorial coordinate system, the right ascension coordinates of these borders lie between 16h 36.1m and 18h 10.4m , while the declination coordinates are between −45.49° and −67.69°. system, as has the system's entry in the Extrasolar Planets Encyclopaedia. Mu Arae (2,415 words) case mismatch in snippet view article find links to article Mu Arae (μ Arae, abbreviated Mu Ara, μ Ara), often designated HD 160691, officially named Cervantes /sɜːrˈvæntiːz/ sur-VAN-teez, is a main sequence G-type [2] The G3 part means the star is similar to the Sun (a G2V star). [20] Close to Beta Arae is Gamma Arae, a blue-hued supergiant of spectral type B1Ib. Ib supergiant stars", "First direct detection of a Keplerian rotating disk around the Be star α Arae using AMBER/VLTI", "Precise radial velocity measurements of G and K giants. Ara (Latin: "The Altar") is a southern constellation situated between Scorpius and Triangulum Australe. [25] Alternatively it may have formed in the inner regions of the Mu Arae system as a rocky "super-Earth". [35] Mu Arae (Cervantes[36]) is a sunlike star that hosts four planets. With 1.12 times the mass of the Sun, it has an outer envelope that has expanded to 40 times the Sun's radius. MOTNK x Mu Arae Song 2,694 Views. In the early days of printing, a 1482 woodcut of Gaius Julius Hyginus's classic Poeticon Astronomicon depicts the altar as surrounded by demons. [27] Were it not dimmer by intervening interstellar dust, it would be significantly brighter at magnitude 2.11. [11] Since the parameters of the outermost planet were poorly constrained before the introduction of the 4-planet model of the system, this results in a different order of designations for the planets in the Mu Arae system. Education is of great importance in socialization. In 2006, two teams, one led by Krzysztof Goździewski and the other by Francesco Pepe independently announced four-planet models for the radial velocity measurements of the star, with a new planet (Mu Arae d) in a near-circular orbit lasting approximately 311 days. Further observations revealed the presence of a second object in the system (now designated as Mu Arae e), which was published in 2004. Eng.) [12] The official constellation boundaries, as set by Belgian astronomer Eugène Delporte in 1930,[c] are defined by a polygon of twelve segments. II. Its four known exoplanets were named Quijote, Dulcinea, Rocinante and Sancho, after Cervantes’ characters. Miguel de Cervantes Saavedra (1547–1616) was a famous Spanish writer and author of El Ingenioso Hidalgo Don Quixote de la Mancha. The established convention for extrasolar planets is that the planets receive designations consisting of the star's name followed by lower-case Roman letters starting from "b", in order of discovery. [26], Delta Arae is a blue-white main sequence star of spectral type B8Vn and magnitude 3.6, 198 ± 4 light-years from Earth. Mu Arae c, the innermost, was the first hot Neptune discovered. The radius of the star is 36% greater than that of the Sun and it is 90% more luminous. The Milky Way crosses the northwestern part of Ara. The Castle of Knowledge by Robert Record of 1556 lists the constellation stating that "Under the Scorpions tayle, standeth the Altar. Seven star systems are known to host planets. Bradt, H.V.D., and McClintock, J.E., Annu. [11] Its position in the Southern Celestial Hemisphere means that the whole constellation is visible to observers south of 22°N. انتخاب باز یا بسته بودن الگو. ";[7] a decade later a translation of a fairly recent mainly astrological work by Marcellus Palingenius of 1565, by Barnabe Googe states "Here mayst thou both the Altar, and the myghty Cup beholde."[8].
