fusion involves H fusing into He. Here, the H is escaping unfused & where does the O come from? the breath of god?

What is the dilemma there, the fusion process is not creating the oxygen, it is simply providing energy that is causing its ejection.

Quite a phenomena, though, I'll second that.

Most interesting.

4 x He could fuse to make 1 Oxygen atom, at least in theory.
http://en.wikipedia.org/wiki/Helium_fusion

Certainly Oxygen is one of the most common elements on Earth and on the Moon.  It is also interesting that it is common in comets.

In fact, Oxygen is listed as the 3rd most common element in the Milky Way.
http://en.wikipedia.org/wiki/Abundance_of_elements_on_Earth

What is interesting here is that the stellar wind is typically thought to contain ions.  I had always thought of + ions.  However, I suppose one would be much more likely to find Oxygen as a negative ion.

And, thus,   O2- + 2(H+) --> stellar rain.

Here is the National Geographic Article relating to this star.  It is interesting that nothing seems to actually identify the star.  Everything suggests a young star, but nothing indicates how big, or the stellar class.
