At minimum, Mira is fainter than the Sun and one of the coolest stars known (surface temperature of about 1,900o K); at maximum, it is 1,500 times brighter. It weighs in a 15.7 solar masses. The light curve is on page 631 of Burnham's "Celestial Handbook". The variability of this star was discovered in 1596 by the Dutch astronomer David Fabricus, although he thought it was a nova and hence did not see its recurrence a year or so later. Bayer included it in his star chart of 1603. Since at the time of the discovery of its variability (around 1638), no other variable stars were known, it was given the name Mira (meaning "wonderful"). Long period variables are fairly common. They tend to have large fluctuations in magnitude (5 to 6 is common, 10 has been observed in some cases), and the periods are long (60 days up to 700 days or more). The periods are slightly irregular. All known LPV’s (as they are called) are red giants, usually of spectral class M, and are in late stages of evolution, having just left the Main Sequence. Internally, Mira is probably starting to burn helium in its core, with hydrogen being burned just outside the core. Mira actually has a tiny variable companion lying about 0.5 seconds away, but I doubt if you’ll ever spot it with an 8" telescope. Robert Aitken (using the 36" Lick refractor) barely glimpsed it in 1923! If astronomers can work out the orbital elements of this little companion, they would have an important scale with which to "weigh" Mira and thus establish another important parameter in the study of stellar evolution. The companion is a white dwarf some 3,300 times denser than the Sun. -8- Zone 158 So try to picture this in your mind— for millions of years, two stars orbited one another, both of them several times more massive than the Sun. The more massive star evolved faster and left the Main Sequence millions of years ago, flashed through its red giant phase and evolved slowly into a white dwarf. Meanwhile, its scorched survivor (Mira) also aged and, in our day, leaves the Main Sequence to follow its mate in the protracted death dance of a large star. There is a 9.3m optical companion at 121+” @ 71o. Mira lends its name to a whole class of long period variables (stars with periods of 80 to 1,000 days or so), in which the magnitude fluctuates from 2.5 up to 10 magnitudes (visually— the infra-red and bolometric magnitude changes are smaller). They are numerous and all have irregular light curves. 90% of them are Me stars and the rest are carbon stars and zirconium stars. All pulsate and most have evidence of shock waves in their atmospheres. This pair may be optical. Mark Reid and Joshua Goldston (of the Harvard-Smithsonian Center for Astrophysics) have a theory that goes against common sense— at first. They propose that Mira is dimmest when it is largest, and that the dimming is caused by the formation of titanium oxide in its vast outer envelope as it swells. TiO is fairly opaque to visible light (it is often used in sunscreens!). In the Reid-Goldston model, the stellar envelope that lies above the TiO layer is so dim that it contributes little visible light to Mira's image. AB 1923: 0.9 @ 132. 66 measurements.

From James Kaler's Star Notes: Mira is the brightest of the red class M "long period variables," thousands of which are now known. Our star varies from about third magnitude (though sometimes it can reach second) way down to tenth, 40 or so times fainter than the human eye can see alone, and then back again over a 330 day period. As a result it is sometimes a part of its constellation, sometimes not. Mira, with a temperature just above 2,000 degrees Kelvin, is one of the coolest stars in the sky. The star is approaching the last stages of its life. Long ago, the hydrogen fusion that powered its core ran out, and then the by- product of that fusion, helium, fused to carbon and oxygen, and now the helium has also run out. The result of these internal changes is a hugely distended, very luminous star that is double the size of the orbit of Mars. Hubble Space Telescope observations show that the star is so unstable that it is not even round. The light variations are caused by pulsation, changes in size that also affect the star's temperature. Mira's great size and instability promote a wind that will soon blow away its outer envelope, the inner nuclear burning portions condensing into a burnt-out "white dwarf," a tiny star the size of Earth, the rest of the star lost to interstellar space. These long period variables help enrich the interstellar gases, out of which new stars condense, with chemical elements formed in -9- Zone 158 their nuclear cauldrons. Most of the carbon in the Universe seems to have come from them. Mira has a white dwarf companion to which all these events have already happened. Many billions of years from now, the same will happen to our Sun. Observations: C8 at 104x. C11 at 115x. Model (where the Sun is a baseball): Diameter: A = 125 feet.

Mechain on October 29. It is 100,000 light years in diameter and is a Seyfert galaxy with a nucleus that is 40,000 light years in diameter. It is also a little unusual in that it boasts of three spiral arms. Recent photos with the repaired Hubble Space Telescope shows a double cone erupting from the core, a possible tell-tale signature of a black hole at the core. M77 has a mass of 100 billion suns and is 80,000 light years in diameter. It was one of two galaxies in which large redshifts were first detected by Vesto Slipher (1913; the other galaxy was M104, the "Sombrero"). It is a Seyfert galaxy. Seyfert galaxies emit intense and variable ultraviolet radiation from tiny, brilliant nuclei, and may be linked evolutionally to quasars. In fact, in the heart of M77, moving gas clouds of about 10 million solar masses have been clocked at over 360 miles per second velocity! Other Messier Seyferts include M82 and M87. Observations: C8 at 65x. Small nucleus with a bright halo; round. It takes high power well. An 11m star is on the E edge. It runs NE-SW and you'll find averted vision a help.
