with such an origin. Helium burning produces18O from14N, which dominates the CNO isotopes in material that had undergone hydrogen burning via the CNO cycle. As a consequence, the H/C zone in pre-SNII massive stars (seeFigure 9), which experienced partial helium burning, has a high18O ...
I am on a tall mountain top with no trees looking up at the perfectly clear and calm sky right now. It is midnight. I can now see approximately half the stars in the sky. These near perfect seeing conditions make it so that I can see stars to magnitude 6 with my 20/20 vision. Nu...
calculations show that the entire core is ignited in a quick burst of fusion called ahelium flash. (More massive stars also ignite helium but more gradually and not with a flash.) As soon as the temperature at the center of the star becomes high enough to start the triple-alpha process...
Most stars travel the galaxy with companions or in clusters. But not all stars do that; our Sun, for example, moves through the galaxy without a stellar companion. When you look at a star (or any object in space) you are seeing how it looked in the past. The Sun appears as it was...
that more evident than in the gleaming moon cities of Awai Sashai, where the privileged, socially elite live close to the stars, far from those who walk the city streets. It’s a place where an under city cabaret dancer and a daemon prince could never hope to meet. That is, until LS...

In practice, the kinds of baselines surveyors use for measuring distances on Earth are completely useless when we try to gauge distances in space. The farther away an astronomical object lies, the longer the baseline has to be to give us a reasonable chance of making a measurement. Unfortunatel...
