July 7 clue

[itsmar...@gmail.com]

This object is a ring, with a jewel, containing a type G "barium" and a hot white dwarf binary star system.  Visible tonight.

I don't know if this one is easy or difficult.  I learned something interesting about it.

Guesser gets to post tomorrow's - but not until tomorrow.

We are a very few at this point on the list.  I will post

Abell 70?

The "jewel" in the ring is a background galaxy, and the barium-enhanced G-type star is the companion of the binary central star!

Can't fool experts!  Nice clarification too, you're more precise than Wikipedia (haha)!

Wait - are you saying the binary pair is actually a three star system?

It your post tomorrow.

No, I don't think the binary pair is a 3-star system. It is a white dwarf + the barium-enhanced sub-giant star. Actually, that is also what Wiki says!

Damn I wouldn’t have figured this out. I know nothing about the G-type and barium.

But yes, the diamond in the ring is a background galaxy.

I thought this was called “the Diamond Ring of Aquila” officially, but looks like it’s a nickname I made up for it. I like it enough to perpetuate it.
