The following is a list of stars with resolved images, that is, stars whose images have been resolved beyond a point source. Aside from the Sun , observed from Earth , stars are exceedingly small in apparent size, requiring the use of special high-resolution equipment and techniques to image.
Enneagram, a nine-pointed star polygon; Decagram, a ten-pointed star polygon; Hendecagram, an eleven-pointed star polygon; Dodecagram, a twelve-pointed star polygon; Magic star, a star polygon in which numbers can be placed at each of the vertices and intersections, such that the four numbers on each line sum to the same "magic" constant
A-type stars are among the more common naked eye stars, and are white or bluish-white. They have strong hydrogen lines, at a maximum by A0, and also lines of ionized metals (Fe II, Mg II, Si II) at a maximum at A5. The presence of Ca II lines is notably strengthening by this point.
Canes Venatici (/ ˈ k eɪ n iː z v ɪ ˈ n æ t ɪ s aɪ / KAY-neez vin-AT-iss-eye) is one of the 88 constellations designated by the International Astronomical Union (IAU). It is a small northern constellation that was created by Johannes Hevelius in the 17th century.
The star-effect may be also caused by the inclusions of hematite. In black star sapphire hematite needles formed parallel to the faces of the second order prism produce asterism. Some star sapphires from Thailand contain both hematite and rutile needles forming a 12-ray star. [3] Star-stones were formerly regarded with much superstition. [1]
At the centre of the Cat's Eye Nebula is a dying Wolf Rayet star, the sort of which can be seen in the Webb Telescope's image of WR 124. The Cat's Eye Nebula's central star shines at magnitude +11.4. Hubble Space Telescope images show a sort of dart board pattern of concentric rings emanating outwards from the centre.
Stars tend to fall only into certain regions of the diagram. The most prominent is the diagonal, going from the upper-left (hot and bright) to the lower-right (cooler and less bright), called the main sequence. In the lower-left is where white dwarfs are found, and above the main sequence are the subgiants, giants and supergiants.
According to traditional Chinese and Japanese face reading, the eye is composed of two parts, the yin (black, iris and pupil) and the yang (white, sclera).The visibility of the sclera beneath the iris is said to represent physical imbalance in the body, and is claimed to be present in alcoholics, drug addicts, and people who over-consume sugar or grain.
