Animations show the evolution of density and flow in simulations of a planet embedded in the envelope of a giant star, showing the interactions of the inspiralling planet with the gas in its vicinity.

The world's most elaborate cosmological simulation of the evolution of our universe was recently completed by astrophysicists. For the first time, a hydrodynamic cosmological simulation is large ...

A snapshot from a hydrodynamical simulation of a three-solar-mass star, which shows gravity waves generated by turbulent core convection propagating throughout the star's interior. Gravity waves in ...

When our sun exhausts the hydrogen fuel in its core some 5 billion years from now, it will expand to become a red giant, engulfing the inner planets. The dynamics and possible outcomes of planetary ...
