I saw a report showing that there is a greater liklihood for planets around low metallicity red dwarfs, as opposed to the higher ones. But, they were quick to point out that this was from a very small sample of red dwarfs.

Let's see.... To discover a zero metallicity red dwarf would tell me one thing for sure....someone has got a fantastic telescope! Envy².

Bludgeoning further....

Pop III stars are Texas stars -- "The stars at night, are big and bright, thump-thump-thump-thump, deep in the heart of Texas" --, so, perhaps, they belch little reds during some sort of nascent T-Tauri phase.

Surely others here know more of the Pop III cosmology to know this answer before I Google it.

Pop III and their supposed properties is a good place to start further exploration.

As for telescopes: Let's say the star was found in the local universe (with a small "u")

I recall a red dwarf in our galaxy's halo that had very low metalicity, but not zero. I hope someone knows it. It is logical it would be local since it is observable.

Of course - I just wanted to make clear that I wasn't referring to some hypothetical main seq RD in galaxy far, far away, but, sort of, right here.

Yes zero - not almost zero - is the point. I wouldn't mind miniscule amounts of Lithium, though I am not that wouldn't get destroyed pretty soon.

Any more hints required?

O.K., I'll wait until tomorrow for solutions or requests for hints. After that I'll solve. Since George is the only one who made an effort to solve this, I suggest the next question come from him.

O.K., sorry that this wasn't fun.

The paper is in Science 317, pp.1527-1530.

Such a star would tell us about the temperature of Dark Matter: Clumping would be different in a warm DM Universe, and it would allow for the formation of small first generation (= zero metallicity) stars, whereas cold DM models call for a first generation of stars that were supermassive and are thus long since gone.

I guess it's your turn, George.

:blush:

That's amazing.

It's us that flopped. Try another one, Arneb.

Fascinating! Glad to see that it was worth the wait.

I was pretty much stumped by the question. The only thing I could think of was age - and George was shot down when he guessed that!

Yes, I found the story absolutely thrilling, too. I had hoped that there would have been some article on the Net or in some magzine (as it was in my case) that someone would have read or heard about. Admittedly, the original article's abstract (I don't have access to the full text) doesn't mention small pop III/zero metallicity stars directly; it deals more with subtle differences in large scale structure formation that the difference between CDM and WDM would create.
However, the possibility of the formation of small pop III stars seems to be a relatively straightforward conclusion from modelling the physics of plausible "warm" Dark matter candidate particles.

I'll think of something for a new round. I'll be back after the next commercial...

Thanks for staying through the commercial *burp*

Here is my subsitute question, again harvested form my current stack of astronomy magazines.

Small rectangular affair, fits in a hand. Costs a bit more than $ 100. It is operated with standard batteries. You hold it up without support of a tripod. Push a button. Beep. Done.

What is it, and which important astronomical parameter did you just measure?

It's a microwave disgronifyer. It measures the microwaves coming from gov. satellites and tells you if you need to wear your tin foil hat.

That would be measuring "sky brightness".

Congratulations, and thanks, eveyone, for bearing with me for so long.

On to you, Dave

Oh, great! I never expected to answer your last query so quickly so I'll need some time to come up with a worthy question.

Let's try another 20 Questions quiz. Name the astronomical object that I have in mind and its classification.

And, of course, comes the traditional start-off question...

Is it bigger than an astronomical bread box (1 cu. lyr.)? [It beats, "Is it animal, vegetable, or mineral?".]
