During this phase, the sun makes a transition from burning hydrogen in the core to burning hydrogen around the core, which has been converted into helium by hydrogen burning. The energy production ...

Neutrinos generated through solar fusion reactions travel effortlessly through the sun's dense core. Each specific fusion ...

The line became known as the main sequence. Competing groups of astronomers came up with different ways to categorize main ...

the sun will enter the red giant phase. During this phase, it switches from burning hydrogen in the core to burning hydrogen ...

Evans found that the 4686 series and the Pickering series can be obtained in a helium spectrum showing no trace of the ordinary hydrogen lines. These series were observed a few years ago by Prof.

In a star like the Sun, four atoms of hydrogen eventually combine via fusion to make a heavier nucleus of helium. What makes fusion inside a star so useful is that the transformation of a light ...
