Aldebaran, Alpha Tauri, also known as the Eye of Taurus, is an orange giant star located at a distance of 65 light years from Earth. The winding progression groupings of the chief can be considered and the pair have a truly extraordinary float of 51.4 days. The star expands, but at the same time its surface temperature is relatively cooler. These are the two brightest predictable celestial objects after the Sun; think photo opportunity. The primary star is a blue-white dwarf and the companion is a white subgiant. The Hyades are a star cluster located in Taurus constellation and the nearest open cluster of stars to the solar system. It is regarded as a red clump giant that burns helium at its core. The position of ε Tauri in the Taurus constellation. Read More »Aldebaran. Orbital Distance. She possibly has a child, in which she orbits, he is afraid of her, for she is dying, and growing a lot. Sunday, April 26 Now the Moon hangs left of Venus for skywatchers in North America.

The system included eight planets and was the namesake for the Eta Serpentis sector, which it was located in. Hop 1.8 degrees west and slightly to the north for an incredibly unusual variable star – T Tauri. The planet orbits Epsilon Tauri every 1.6 years in a somewhat eccentric orbit. [1 Epsilon Tauri (ε Tauri, abbreviated Epsilon Tau, ε Tau), formally named Ain /ˈeɪn/, is an orange giant star located approximately 45 parsecs (147 light-years) from the Sun in the constellation of Taurus. Control. Epsilon Tauri is a giant orange star 147 light years from Earth, it is part of the Hyades cluster, in which it lives in it 625 million years, it is beginning to die, becoming exhausted in the fuel. In the RGB stage, the star is fusing Hydrogen in an outer shell and Helium in its core. Le mot epsilon peut renvoyer à : Epsilon, lettre grecque ; Epsilon Euskadi, une équipe de course automobile ; Ouragan Epsilon, un… …   Wikipédia en Français, Ε Tauri — Epsilon Tauri Pour les articles homonymes, voir Ain. The brightest stars in the Hyades cluster form a V shape that marks the head of the celestial bull. The temperature was calculated using information from Morgans @ Uni.edu. Epsilon Tauri b is a "super-Jupiter", an exoplanet that has a radius and mass larger than that of the gas giants Jupiter and Saturn. It has an 11th magnitude companion 182 arcseconds from the primary. Epsilon Tauri Four was barely M-class. Epsilon Tau b är en exoplanet som kretsar runt Ain (Epsilon Tauri) på omkring 144 ljusårs avstånd i stjärnbilden Oxen.. Epsilon Tau b kretsar på ett medelavstånd av 1,9 AU och gör ett varv runt stjärnan på ungefär 594 dygn.Planeten är troligtvis en "het Jupiter", med en massa på 7,34 gånger Jupiters. Also catalogued as Collinder 50 or Melotte 25, the cluster has an apparent magnitude of 0.5 and lies at a distance of 153 light years, or 47 parsecs, from Earth. Our journey will start by identifying Aldeberan (Alpha Tauri) and move northwest to bright Epsilon. The Moon's dark limb will occult Epsilon Tauri in the Hyades, magnitude 3.5, for eastern Canada and the northernmost eastern US. Even so, it is way more cooler, as it has a temperature of only 3.900 K, while the Sun is at 5,778 K. Its name is translated to "the follower," as it keeps close to the … In 2007 a massive extrasolar planet was reported orbiting the star. The star varies slowly in brightness between magnitude 0.75 and 0.95. At the time of the discovery it was the only known planet in an open cluster. An LTE analysis indicates that slightly higher turbulent broadening in epsilon Tau can account for the observed differences in line-width. It rotates very slowly, with a projected rotational velocity of 3.5 km/s, taking 520 days to complete a rotation. It has an 11th magnitude companion 182 arcseconds from the primary. http://webviz.u-strasbg.fr/viz-bin/VizieR-5?-out.add=.&-source=I/311/hip2&recno=20836, "Directly Determined Linear Radii and Effective Temperatures of Exoplanet Host Stars", http://www.iop.org/EJ/abstract/0004-637X/694/2/1085/, "A Planetary Companion to the Hyades Giant ε Tauri", http://www.iop.org/EJ/article/0004-637X/661/1/527/21184.html, http://www.frostydrew.org/observatory/columns/essays/starnames.htm. These K0 III stars, with L(X) ~ 10^30 erg/s, are an order of magnitude brighter in X-rays than the typical Hyades corona, and 30-50 times brighter than the remaining Hyades giants, delta and epsilon Tauri. Ain - ε Tauri (epsilon Tauri) Ain, also designated as ε Tauri (epsilon Tauri), is a double giant star in the constellation of Taurus. [3] Given its large mass, this star was formerly a member of spectral type A that has now evolved off the main sequence into the giant phase. Allowing for a bit of infrared radiation leads to a luminosity 74 times that of the Sun, which with temperature gives a radius of 11.6 solar and a mass of 2.6 Suns. The plot is based upon averages of all observations received within one day, and lines connecting the observations have been added as a visual aid. ] As a member of the Hyades cluster, Epsilon Tauri's age is well constrained at 625 million years. Her son was the first extrasolar planet to be discovered in a cluster, Hyades. Temperature of Ain 4719K. 0.8 AU. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between between 3,500 and 5,000K based on the notes from Harvard University. An extrasolar planet (designated Epsilon Tauri b, later named Amateru) is believed to be orbiting the star. Epsilon Tauri (ε Tau, ε Tauri) is an orange giant star, spectral type of K0 III, located approximately 147 light-years [1] away from the Sun in the constellation of Taurus.It is a member of the Hyades open cluster.It has the traditional names Ain (Arabic عين), or Oculus Borealis, both of which mean "eye".. Auf Grund seiner hohen Masse wird angenommen, dass es sich um einen Gasplaneten handelt. Eta Serpentis is a star system, a type K orange star in the space of the galaxy's Alpha Quadrant. As most open clusters dissolve before they reach a billion years in age, the Hyades are expected to lose members and mass over the next few hundred million years until they are reduced to about a dozen star systems, which will eventually dissipate, too. Epsilon Tauri (ε Tau, ε Tauri) is an orange giant star, spectral type of K0 III, located approximately 147 light-years [1] away from the Sun in the constellation of Taurus.It is a member of the Hyades open cluster.It has the traditional names Ain (Arabic عين), or Oculus Borealis, both of which mean "eye"..

The star has a B-V Colour Index of -0.08 which means the star's temperature is about 11,099 Kelvin. It has the traditional names Ain (Arabic عين), or Oculus Borealis, both of which mean "eye". The star bore the regular name Ain (Arabic نيع for "eye") and was given the name Oculus Boreus (Latin for "Northern eye") by John Flamsteed. Thuban is a specific lined spectroscopic same. Since Epsilon Tauri lies near the plane of the ecliptic, it is sometimes occulted by the Moon and (very rarely) by planets. The red dot in the diagram below shows where Ain is situated in the Hertzsprung–Russell diagram. With an effective temperature of 12,258 K, the star is 2,030 times more luminous than the Sun, but most of its output is … Coordinates: 04h 28m 37.0s, +19° 10′ 49″, Epsilon Tauri b — ist ein Exoplanet, der den Roten Riesen Epsilon Tauri alle 594,9 Tage umkreist. Study of two particularly temperature sensitive features confirms earlier observations that the effective temperature of epsilon Tau is less than that of gamma Tau and determines the temperature difference to be 80 +/- 20 K. 31 °C. After the RGB stage the Horizontal Branch is 3844. With a surface temperature of 3,900 K, it shines with a luminosity 439 times that of the Sun, with a lot of its energy output being in the invisible infrared. Also catalogued as Collinder 50 or Melotte 25, the cluster has an apparent magnitude of 0.5 and lies at a distance of 153 light years, or 47 parsecs, from Earth.
