Why Do Stars Emit X Rays?
DOI: 10.1063/1.881079
The Sun was the first observed x‐ray star. In 1948 rocket‐borne instruments, carried out of the terrestrial atmosphere for only a few minutes at a time, detected solar x rays. Then in April 1960 instruments recorded the first x‐ray photograph of the Sun.
