  What's Up - Constellations (Apr)
Pollux is a solitary star, located some 35 light years from us, and is a typical aging orange giant star which has swollen in it's final years to span eleven times the diameter of our sun.
Interestingly, Pollux is located at almost the same distance from us as the familiar Arcturus now visible in the east; Pollux appears fainter to us as Arcturus is of twice the actual light output, a rare chance to compare stars of a similar type at an equal distance.
An eighth magnitude star in the telescopic field with Zeta is merely aligned by accident; the stars are in fact nowhere near one another in distance.

 systemic - Pollux
Pollux is about 1.9 times more massive than the Sun, and is already coming to the end of its life.
Higher mass stars also tend to be fast rotaters, which further smears out the lines, and they are often subject to pulsations which can mimic the radial velocity signature of an orbiting planet.
The atmosphere of the star then regains the wealth of spectral lines that can be used to make accurate radial velocity measurments, and hence detect planetary companions.

Both the stars in the circle and the Black Hills contain time in their mirrors of each other, but not in the same way.
Old Baldy, a bare place in the Hills marks the center of the ceremonial geography -- but there is no star or constellation to mark the starry circle's center in the sky, the correspondence is 2 different kinds of empty places.
As can be seen from the Lakota book's re-vivification of Lakota star knowledge (which took many years of work by native scholars), attacks on Native religion were really attacks on entire lifeways, since religion wasn't something separate, all forms of knowledge were at risk, and all methods of preservation had to be clandestine.
