From James Kaler's Star Notes:
Its distance of 175 light years allows us to calculate a true luminosity that to the eye
would be 400 times that of the Sun. With a temperature of 4,000 degrees Kelvin, the term
"giant" is apt, as the star is some 40 times larger than the Sun. Placed at the solar
position, Alphard would extend halfway to the orbit of Mercury. As such the star is in
league with several others that include both Arcturus and Aldebaran, which are more
prominent because they are closer to us even though Alphard is actually a bit more
luminous (making it a so-called "bright giant.").
Alphard also distinguishes itself by being a mild form of "barium star," in which
barium and other elements that are formed by the slow capture of neutrons are enhanced.
Barium stars are thought to be doubles. When Alphard was young, it had a more massive
companion that died first, and in the process contaminated it with the by-products of
nuclear fusion that had been shovelled to the top. The companion has now died as a dim
white dwarf, and the star that that had been contaminated is now itself dying, presenting
us with evidence for what once happened.
Observations:
C8 at 104x.

Class: (R)SA(rs)0/a
Dimensions: 3' x 2'
Magnitude : 11.6

Observations:
C8 at 104x. It is a very faint and diffuse glow that yielded no details to my Kansas
City light-polluted attempts. A 13m star lies very close to the nucleus. It is 26 min E of a
4.8m 26 Hya and 19 min S of 8.3m SAO 155113.
