Notes: AB 1830: 19.4 @ 208. 37 measurements. This is an optical pair. Star A is a spectroscopic binary (30 year orbit) and a Cepheid with a 3.9698 day period. It is 10 times as massive as the Sun and was found to be a binary by William Herschel in 1779. AC 1884: 43.3 @ 88. 5 measurements. AD 1884: 82.7 @ 172. 2 measurements. Polaris is a member of the Pleiades Group. From James Kaler's Star Notes: Because of a 26,000 year wobble in the Earth's axis, the pole of the sky is slowly moving closer to Polaris, and then, around the year 2100, will start to pull away. Thousands of years from now, Polaris will be well off the pole, other stars someday taking its place. The star is actually an evolved class F yellow supergiant. Hydrogen fusion has stopped in the star's core, and it is now passing through a phase of instability wherein it pulsates over a period of about four days, almost invisibly changing its brightness as the brightest "Cepheid" variable star in the sky. The prototype of this kind of star, Delta Cephei, though fainter, is a much more obvious variable, its changes easily seen with the naked eye. Cepheids are paramount distance indicators in astronomy, as their true brightnesses are revealed by their periods of oscillation. Polaris is particularly interesting as the pulsations have nearly, but not quite, ceased. Just as a violin string has a -2- Zone 1 "fundamental" tone that gives its pitch, it also vibrates in higher-frequency overtones. Comparison with other Cepheids shows that Polaris is pulsating not with its natural fundamental period, but in its first overtone. The star may be in the process of evolving into its fundamental period of 5.7 days to become a more-normal Cepheid with a greater variation. Observations: C8 at 104x. Some observers report yO and B.
