pleased to see binaries addressed

Awake now.

Grabbed the National Geographic magazine Special Edition Atlas of the Night Sky.

5:45 AM. Skimmed what I had read so far. Including the chapter Our Sun and Other Stars

Page 10.

Noted, in my morning haze, the infographics in the small table entitled "Multiple Star Systems." A simple binary with equal stars to a double-double, two pairs orbiting each other.

Oh. Oh ho!

They were talking about hierarchy structures! Yes, double star types, binary systems and their masses. Very cool. I was very pleased to see this here. On many levels.

Common question raised at star parties: are these stars related?
