Alpha Peg (54 Peg; Markab; HD 218045; SAO 108378)
Position: 2305+1512
Mag : 2.49
Spectrum : B9.5 III Color : bW
Assumed distance: 140 light years
Assumed luminosity (suns): 205
Notes:
This star is an infra-red source and a spectroscopic binary. It rotates at 148 kps.
From James Kaler's Star Notes:
Markab epitomizes what seems almost to be a celestial joke, a comic opera of sorts in
which stars scramble their names and appear as different characters on the sky's stage.
Four stars make the Great Square of Pegasus, Markab (Alpha) at the southwestern corner,
Scheat (Beta) at the northwestern, Algenib (Gamma) and the southeastern, and Alpheratz
(Alpha Andromedae) at the northeastern, this last star linking the Winged Horse to
Andromeda. "Markab" comes from an Arabic phrase meaning "the horse's shoulder," but
in more recent times was mistakenly taken from what is now Scheat. But Scheat's name
("the shin" was mistakenly taken from "Skat," the Delta star in Aquarius. Continuing the
confusion, Algenib's name was taken from Mirfak (the Alpha Star in Perseus), whose
alternative name is also Algenib. Not to be outdone, "Alpheratz" may have come from an
original name for Scheat. The Greek letter system is not much better. As a linking star,
Alpheratz— Alpha Andromedae— is also Delta Pegasi. Moreover, Mirfak, the Alpha
star, just barely second magnitude (2.49), is only third brightest in the constellation, and
is exceeded by both the Beta star (Scheat), by of all things, Epsilon (Enif), as well as by
the Delta star (Alpheratz of Andromeda). There will be a quiz on all this next Tuesday.
Markab itself is much clearer. It is a relatively hot (class B, though at the cool end)
giant, appearing not much different from (though visually fainter than) Regulus in Leo.
The star's temperature (10,500 Kelvin) yields a radius 4.3 times solar. Just a hair over
three solar masses, and still spinning fairly rapidly (its rotation period under 1.5 days),
Markab has just begun to die. If hydrogen fusion has not already ceased in its core, it is
very close. The star is in a sense clinging to its lifeline on the hydrogen-fusing normal
"main sequence" of stars and is about to leap into the abyss, in which it will quickly
expand, slow its rotation, and become a much cooler orange giant (perhaps someday
looking like Kornephoros in Hercules). It will then brighten to many times its current
luminosity to die finally as a massive white dwarf like Sirius-B. Some stars are
remarkable for their chemical compositions, others for their multiplicity, yet others for
strange variability. Though there is some evidence from Markab's motion for a small
stellar companion, the star is famed for none of these. It is in fact noted for its very
normality, behaving quite like it should. Such normalcy is extremely important in stellar
-9-
Zone 153
astronomy, as it provides a bedrock standard against which to measure the odder
members of the stellar zoo. Of the 100 publications in which Markab has been mentioned
in the past 15 years, nearly all use it as such a base.
