Lasers and star models

Astronomy was long time just observational science, observing celestial bodies. Now is possible to model and study some celestial objects. Critical is understanding of behaviour hydrogen, the most common element,  and another elements  under extreme conditions, like inside of stars, planets or interstelar clouds. Extreme conditions could be created by powerfull lasers,such studies are conducted for example by Gianluca Gregori’s Research Group at the University of Oxford.
