Reference Star
Alpha Ari (Hamal; Arabic for the whole constellation; HD 12929; SAO 75151)
Position: 0207+2328
Mag : 2.00
Spectrum : K2 III Color : Y
Assumed distance: 66 light years
Assumed luminosity (suns): 90
Notes:
Star A is a spectroscopic binary and an infra-red emitter.
From James Kaler's Star Notes:
The vernal equinox, the point, where the solar path crosses the celestial equator, is in
Pisces south of the west edge of the Great Square of Pegasus. Over 2,000 years ago,
however, it was in Aries, having shifted westward into Pisces because of precession, the
26,000 year wobble of the Earth's axis.
True to form, Bayer called Hamal the Alpha star and the second brightest (Sheratan)
Beta, but then quite broke down as the third brightest (Flamsteed 46) has no Greek letter
at all.
Hamal is a warmish class K orange giant star. At a distance of 66 light years, it shines
(allowing for infrared radiation) 90 times more brightly than our Sun. From this figure
and an accurate temperature of 4,590 Kelvin, the star is calculated to be 15.0 times the
solar diameter. Hamal is characterized mostly be being so very normal, at least as far as a
dying giant about twice the solar mass can be. Very little about it is unusual except for a
mild deficiency in metals compared with the Sun. That in itself makes it rather valuable
as a comparison for other stars.
It has the honor of having (along with Shedar, Alpha Cassiopeiae) the most
accurately-measured angular diameter, 0.00680 seconds of arc (a penny 60 kilometers
away), from which we find another value for true diameter of 14.7 solar, beautifully in
accord with that found from temperature and luminosity. This precise measurement
allowed the detection of Hamal's "limb darkening." As a gaseous sphere, the Sun is
slightly darker at the edge (its "limb") than at the center, the result of our not looking as
deeply into the solar gases. Similar limb darkening can be detected in the members of
eclipsing stars as they get in front of each other. Hamal is one of the select few single
stars for which limb darkening has been seen, showing that we are not far from observing
features on the surfaces of at least some of our stellar neighbors.

different distances (640 and 98 light years).
B is actually double, with a 11.5m companion at 0.5 @ 110 (1979).
A also has a 13.5m companion at 4.2 @ 328 (1930).
