  Hyades - LoveToKnow 1911   (Site not responding. Last check: 2007-10-20)
HYADES (" the rainy ones"), in Greek mythology, the daughters of Atlas and Aethra; their number varies between two and seven.
As a reward for having brought up Zeus at Dodona and taken care of the infant Dionysus Hyes, whom they conveyed to Ino (sister of his mother Semele) at Thebes when his life was threatened by Lycurgus, they were translated to heaven and placed among the stars (Hyginus, Poet.
Their name is derived from the fact that the rainy season commenced when they rose at the same time as the sun (May 7-21); the original conception of them is that of the fertilizing principle of moisture.

 Hyades (star cluster) - Wikipedia, the free encyclopedia
Its brightest stars form a "V" shape along with the red giant Aldebaran, the brightest star in the field of view, which is not part of the cluster.
The Hyades, at 151 light years from Earth, form the nearest star cluster (disregarding the Ursa Major Stream that includes neighboring stars such as Sirius).
The Hyades, in Greek mythology, were the five daughters of Atlas and half-sisters to the Pleiades.

 [No title]
Hyades is a quintessential argosy of abused thrash allusions.
Hyades even titled their 2004 demo: "No bullshit - just metal!" The main band photo centerfold in the CD booklet is clearly a re-enactment of Exodus - 'Fabulous disaster' artwork.
Hyades won't compromise their sound or style, they won't sell-out, and they are apathetic to anyone else's opinions of them.

 HYADES 1, Greek Mythology Link - www.maicar.com
The HYADES 1 were sisters of Hyas, or else his daughters, and when Hyas died while hunting, killed by a lion, a boar, or a Lybian lioness, they grieved his death exceedingly, and turned into the stars called Hyades which are in the constellation of Taurus.
Also the HYADES 1, who previously were the NYMPHS DODONIDES [see NYMPHS], are called nurses of Dionysus 2, and it is said that they, and not Hermes, delivered the god, when he still was a defenceless child, to Athamas 1's wife Ino, so that she and her husband should rear him.
At other times, the HYADES 1 are considered to be the MAENADS who were put to flight by Lycurgus 1, the King of the Edonians (Thrace) or of the island of Naxos, or of the Arabians, who was the first to oppose and expel Dionysus 2.

 Hyades
For the ancient Greeks, the Hyades were daughters of Pleione and Atlas, a giant who carried the heavens on his shoulders.
The Hyades had several sisters, such as the Pleiades and the Hesperides.
Because the Hyades appear during rainy seasons, the Greeks believed them to be messengers of spring rain showers and autumn storms.

 Hyades distance   (Site not responding. Last check: 2007-10-20)
The Hyades is an open cluster of about 100 stars in the constellation of Taurus.
On average the Hyades stars have a proper motion of 0.12 arcsec per year and a radial velocity of +40 km/s.
The proper motions (arrows) of stars in the Hyades converge to a point as the cluster streams pass the Sun.

 ASP: Editorial: The Border
Thus, the Hyades star cluster is a fundamental stepping stone in our path to deriving distances to stars and galaxies, and ultimately, to determining the size and age of the universe.
And to search for Hyades stars, it was possible for the first time to use directly measured, three-dimensional velocities of the stars by combining the stars' parallaxes, proper motions, and radial velocities (measured from the ground, see Hyades SideBar).
The "halo" stars originated with the rest of the Hyades stars when the cluster was born but have gradually moved away from the central regions and are no longer bound to the cluster.

 AllRefer.com - Hyades, in astronomy (Astronomy, General) - Encyclopedia
The Hyades is important as a fundamental calibration point in the distance scale of the universe.
Because it is one of the closest of the open clusters, measurements of parallaxes of its stars as well as the relationship between the apparent and absolute magnitudes of some of its member stars yield similar distance results.
In 1908 L. Boss discovered that the proper motions of all the Hyades stars were converging as an effect of perspective, and that their motions were really parallel.

 Hyades - Star Clusters - Digital Images of the Sky
The scattered group of stars in the central part of the image is the Open Star Cluster of the Hyades in the constellation of Taurus.
The Hyades, also called Melotte 25, can be seen easily by naked eye as a distinct V in the sky.
However you should be aware that the brightest star Aldebaran, which represents the red eye of the bull in myth, does physically not belong to the cluster population.

 Hyades   (Site not responding. Last check: 2007-10-20)
The Hyades, a cluster of stars 150 light years away that makes the head of Taurus, the Bull, appears to surround the bright star Aldebaran (toward lower left), which makes the Bull's glaring eye.
Aldebaran, however, is not a part of the cluster and is less than half the Hyades' distance away.

 Metallian.com - Hyades
Thrash metal band Hyades was formed in 1996 with drummer Omar Cerlotti, but it wasn’t until 1999 that the group issued the Princess Of The Rain demo.
That band was Hatework and this is Hyades, a quartet drawing influences from Tankard, Anthrax Testament, DRI and Pantera.
With an album title that is obviously a knock on Guns N Roses’ Use Your Illusion, Hyades’ thrashing bears a lot of resemblance to Tankard especially where the vocals of Marco Colombo is concerned.

 Hyades
Its age is put at 660 million years old, which, taken together with its motion through space, suggests it has a common origin with the Praesepe cluster.
Although the bright red giant Aldebaran (Alpha Tauri) lies almost along the same line of sight as the Hyades, it is not a member of the cluster and lies much closer to us (about 60 light-years away).
Although visible to the naked eye and therefore known prehistorically, the Hyades appears to have been first cataloged by Hodierna in 1654.

 Distance to the Hyades Star Cluster
To find the distance to the Hyades star cluster using the convergent point method; to recognize the uncertainties in using this method; to summarize the significant results obtained by the Hipparchos satellite and what these results mean for the distance scale of the Universe.
Most distance determinations used for the Hyades have either been based upon the convergent point method or have been judged according to their agreement or disagreement with it.
The Hipparcos results for the Hyades are truly remarkable and have spawned a number of papers on various topics.

The Hyades cluster is just to the west of ruddy Aldebaran, the eye of Taurus the bull, though Aldebaran itself is not a real member of this cluster.
In Greek mythology, the Hyades were the daughters of Atlas and Aethra, and the Pleiades, daughters of Atlas and Pleione.
So the Hyades are older than the Pleiades: about four hundred million years old, compared with a "mere" hundred million for the Pleiades.

 Eclipse Project Hyades to Implement
Eclipse project Hyades announced today its commitment to release an open-source implementation of the UML 2 Test Profile specification (U2TP), which was submitted to the Object Management Group (OMG) on March 3, 2003.
Hyades is committed to implementing the U2TP which is expected to be formally adopted by the OMG later in 2003.
Mike Norman, Hyades project lead and CEO of Scapa Technologies, commented, “The implementation of the U2TP standard in the Eclipse framework offers the Automated Software Quality community an opportunity to move from poorly-integrated, proprietary testing and tracing solutions to a set of interoperable tools based around open standards inside a universal tools platform.

The brightest members of Hyades are visible to the naked eye, in the constellation Taurus.
The distance to the centre of the Hyades cluster is 151 light-years (46.34 parsecs) with an uncertainty of less than one light-year (0.27 parsec).
The cluster has done well to survive so long.The individual stars of the Hyades are bound together by the gravity of the cluster as a whole, and their collective and individual motions are also plotted by Hipparcos.

 The Hyades, Mel 25
At a distance of only about 150 light years, the Hyades form the nearest open cluster to us, disregarding the Ursa Major cluster which appears as spread individual stars.
The common motion of the Hyades and a number of more stars (the Taurus or Hyades stream) and thus their physical connection was first demonstrated by Lewis Boss in 1908, according to Burnham.
The brightest star in the field of the Hyades, bright red giant star Aldebaran (Alpha Tauri), visible on the right hand side of our image, is not a member of the cluster and situated much closer to us (about 60 light years, a factor 2.5 closer than the Hyades).

 The Hyades
This ROSAT PSPC image shows more than 100 X-ray sources in the central region of the Hyades cluster, a nearby open star cluster about 45 parsecs (150 light-years) from the sun.
The Hyades cluster is about 600 million years old; its member stars are quite young when compared to the 4.5 billion years age of the Sun.
The entire cluster is distributed across more than 900 square degrees of the sky so this image only covers a small fraction of the Hyades.

 Hyades
In Greek mythology, two different groups of people were referred to as the Hyades ("the rainy ones").
Their brother was accidentally killed in a hunting accident and the Hyades died from their grief.
The Greeks believed that the rising and setting of the Hyades stars were always attended with rain, hence the association of the Hyades (sisters of Hyas) and the Hyades (daughters of ocean) with the constellation of the Hyades (rainy ones) and called also 'huo pluo'/'pluvius' (the rain bringer).
