Notes: Ward considered it to be a good test of a 4.5" refractor. From James Kaler's Star Notes: We [can] infer a size 50 times that of the Sun and a mass of around six times solar. Sadalsuud is brighter than its constellation-mate Sadalmelik only because it is 140 light years closer to us. Sadal Sund, Sadal Melik and Enif were born together as hot class B stars not dissimilar from the stars that make the Pleiades of Taurus, though clearly not in as tight a cluster or else they would still be bound together. Instead, they must have been born in a looser "association," rather like the stars that make much of Orion today, their motions of the past tens of millions of years separating them, but not so far that they are not easily in sight of one another. From Sadalsuud, Sadalmelik and Enif would both be "zero magnitude" stars. All three also seem to be moving more or less perpendicular to the plane of our Galaxy, an odd motion that implies they were somehow kicked away from their birthplace. With similar ages and masses, all are now probably fusing helium into carbon in their deep cores, and all will die rather soon as massive white dwarfs rather like Sirius B. - 13 - Zone 223 Observations: C8 at 206x.
