A photoionization-confined shell—a dense, shocked layer separating the neutral inner wind from the ionized outer wind—forms closer to the star. We identify this with the recently discovered ...

Researchers at East China Normal University and Queen's University Belfast recently built on the RABBITT technique to distinctly measure individual contributions in photoionization. Their paper ...

Haiyang Li from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has discovered a new competition mechanism in vacuum ultraviolet photoionization of ...
