It is also a strong infra-red emitter and is a Delta Scuti variable. It rotates at 70 kps. From James Kaler's Star Notes: Caph comies from an Arabic phrase meaning "the stained hand," which refers to an ancient cosmetic coloring by henna. Caph is a class F giant (or subgiant, a not-quite-giant) with a 6,700 Kelvin surface, about 900 Kelvin warmer than the Sun. It is not unusual in having a small stellar companion, about which little is known, that orbits it every 27 days. Though called a "giant," the star is really not all that large, only about four times as big as the Sun. The term really refers to the state of Caph's evolution, hydrogen fusion in its core having recently stopped. The star is not so much a physical giant but becoming one, the core now contracting, the star cooling and expanding (though no such changes could be seen in a human lifetime). Caph is thus quite unusual in that it is in a particularly rapid state of evolution, and is in a region of temperature and luminosity called the "Hertzsprung Gap" (after the famous Danish astronomer Ejnar Hertzsprung) in which we find few other stars. It will spend only about one percent of its few billion year lifetime in such a condition. With a mass of around double the Sun's, Caph once probably looked much like Summer's Altair. Of these "gap" stars, Caph has a particularly faint "corona," a halo of hot, magnetically heated gas that radiates X- rays (seen around the Sun during a total eclipse). Caph is also unusual in being a "Delta Scuti" type of variable star, in fact the brightest of the breed. Slightly unstable, and rapidly pulsating, a sort of low-mass - 11 - Zone 34 version of the famed "Cepheid variables," the star varies by about 6 percent in brightness over a 2.5 hour period.

Nachr. 2859 - referred to as "Swift VII" e.g. by Dreyer). J.L.E. Dreyer, in the IC catalog of 1895, describes it as "faint star involved in extremely faint and very large nebula." It was photographed by H.D. Curtis of Lick Observatory on October 8, 1915, but it remained to N.U. Mayall to reveal this object's extragalactic nature in 1935. Edwin Hubble was the first to consider it as a Local Group member in 1936. Nevertheless, this assumption could not be confirmed until the 1960s, when Morton S. Roberts (1962) and Gerard de Vaucouleurs and H. Ables (1965) determined its radial velocity and distance estimates. [Source: http://www.seds.org/messier/xtra/ngc/i0010.html] Observations: C8 at 104x.

Notes: 1781 (William Herschel): 56.2 @ 275. 19 measurements. Optical. The A star is an infra-red emitter. - 53 - Zone 34 From James Kaler's Star Notes: The name "Shedar" comes directly from the Arabic word for "breast," and describes the position of the star in the heart of the ancient Queen. At mid-second magnitude (2.23), and hard to distinguish in brightness from Caph (the Beta star), Shedar still properly received the Alpha designation from Bayer. Shedar is yet another cool (class K) orange giant star, of the kind that so heavily populates the outlines of the constellations. From its substantial distance of 229 light years (and still second magnitude in our sky) we calculate a large luminosity 855 times that of our Sun, the star more in the "bright giant" class. The luminosity, and a temperature of 4,530 Kelvin, lead to a notable size, 48 times that of the Sun. Shedar and Hamal in Aries are the only two stars in the sky whose "limb darkening" has been directly observed (by use of a sophisticated telescope that makes use of the interference properties of light). The apparent disks of all stars, including that of the Sun, are a bit dimmer at the edges than they are at the centers because our lines of sight at the edges do not penetrate as deeply. As a result, Shedar has a very accurately determined angular diameter of 0.00525 seconds of arc, leading to an improved radius 42 times that of the Sun. (The difference from the earlier radius probably involves errors in the temperature or in the estimate of the amount of invisible infrared radiation included in the luminosity, showing how much there is yet to learn). Shedar's chemical composition is close to solar, though the star seems notably deficient in particular elements such as zirconium and europium. The large luminosity suggests a fairly high mass, four to five times solar. Since high mass stars burn out fast, this dying giant, which has ceased core hydrogen fusion, is only 100 to 200 million years old, having begun life as a star much like Regulus in Leo. For all its seeming mundane character, Shedar has a curious history. Various nineteenth century astronomers claimed it could fade to mid-third magnitude. As a result, the star is still called "variable" in most listings. Since the advent of permanent photographic and electronic recording, however, Shedar has shone steadily. We have little idea of the long-term behavior of many stars, and it is worth keeping an eye on Cassiopeia's chair. Observations: C8 at 104x. Webb saw them as Y! and B.

It is also a strong source of infra-red and has a shell surrounding it which is fed by high-velocity mass ejection that varies over time. Not only that, but it is also a spectroscopic binary and an x-ray star and the x-rays appear to originate in super hot flares (100 million Kelvins) on its surface (it may, in fact, be a whole new type of x-ray star; a type sometimes called a nova-like variable). The AB stars are at least 70 AU apart. It is a member of the Cas-Tau OB1 Association. From James Kaler's Star Notes: It has a 25,000 Kelvin (hot class B) surface and a small bit of absorption by the dust of interstellar space that makes the star appear a bit fainter than it would were space clear. Gamma Cassiopeiae is more, however, than just another luminous star, even more than one that is apparently approaching the end of its hydrogen-fusing life. First, it is also unpredictably variable. In 1937, the star brightened almost to first magnitude, and it has been as faint as third. Perhaps its lack of a proper name tells us of ancient faintness. Then, in 1866 the father of the study of stellar spectra, Father Angelo Secchi, discovered that the star radiated light in specific colors associated with hydrogen. Gamma Cas thus has the distinction of being the first known "Be star," the "e" standing for "emission." Be stars are fairly common and weird. All rotate with enormous speed, Gamma Cas spinning at least 300 kilometers per second at its equator, 150 times the solar rate. The rotation and high luminosity conspire to drive mass from the star into a surrounding disk that radiates the "emissions," mass loss apparently related to the brightness variations. Gamma Cas also radiates X-rays, though no one is quite sure why, theories including the transfer of lost mass to a compact companion and magnetic effects similar to those found on the Sun. If any star deserves a name, surely this one does. Observations: C8 at 206x. A diffraction mask helps! Scale model (in which the Sun is the size of a baseball): Diameter: A = 18.0 inches.

Faint and indistinct. The triple Bu 1 lies at the center. With a filter, you may be able to spot a dark lane that cuts into it on the S side. Steve Coe points out that this gives this nebula a "PacMan or Giant Comma shape." It is a most fitting description when you see photos of this nebula. - 85 - Zone 34 Zone 33 Mini-Catalog Double Stars Star Designation Position Rating Map Alpha Cas 0041+5632 1E 6 Eta Cas 0049+5749 1E 9 OSS 254 0001+6021 2E 2 STF 10 0015+6250 2E 1 Espin 1710 0059+5943 2E 8 Argelander 47 0003+5958 3E 2 h1930 0004+6050 3E 2 Espin 1865 0013+6150 3E 1 Espin 2 0031+5648 3E 6 STF 43 0037+6031 3E 5 Courtot 2 0055+5619 3E 9 Argelander 3 0057+6020 3E 8 h1928 0003+6053 4E 2 STF 3057 0005+5831 4E 2 h3241 0008+5722 4E 2 Argelander 1 0009+5937 4E 2 h1003 0011+5755 4E 2 h1010 0016+6006 4E 2 LDS 6088 0020+6046 4E 2 Milburn 277 0027+6430 4E 4 Espin 3 0035+5636 4E 6 Component A B A B A B a b Aa Bb A B A B A B A B A B C A B A B A B A B A B C A B A B A B A B A B A B A B A B - 86 - Specifications Mag Sep from A 2.24 — 8.83 65.5 + 3.46 — 7.24 12.7 + 7.04 — 8.33 58.0 9.49 13.07 155.8+ 133.88.00 — 8.50 18.7 + 8.46 — 9.70 6.4 + 9.28 — 10.07 10.3 + 10.62 — 10.55 10.9 = 9.72 — 9.70 25.0 + 10.44 BC: 4.2 + 8.91 — 10.40 6.4 + 8.41 — 9.01 4.8 + 7.18 — 9.83 62.0 8.33 — 9.19 20.7 10.56 — 10.99 15.3 + 14.00 20.0 6.61 — 9.42 3.5 9.11 — 9.61 15.0 = 9.58 — 9.69 25.5 + 9.35 — 12.50 11.4 + 10.06 — 10.96 20.2 + 9.38 — 10.42 47.6 + 9.99 — 10.40 6.8 = 8.58 — 10.34 5.0 - PA from A — 282 + — 317 -!!
