WebbTheoretical astrophysics covers as wide a range of topics as observational astronomy. Star - and planet-formation models indicate that stars and planets are born from dense, cold clouds of gas and dust, which we describe by modeling the way matter collapses under its own gravity when compressed. Today, researchers model star and planet ...
